RPSC RAS Prelims 2025 Question Paper with Answers & Explanations

Explanation

The Golden Quadrilateral is a flagship highway project of the National Highways Authority of India connecting four major metropolitan cities: Delhi, Mumbai, Chennai, and Kolkata. The four segments and their approximate lengths are as follows. Segment A (Delhi to Mumbai) covers approximately 1,419 km via NH-48. Segment B (Mumbai to Chennai) covers approximately 1,290 km via NH-44. Segment C (Chennai to Kolkata) covers approximately 1,684 km via NH-16. Segment D (Kolkata to Delhi) covers approximately 1,453 km via NH-19. Arranging these segments from longest to shortest gives Chennai-Kolkata (C) at 1,684 km, followed by Kolkata-Delhi (D) at 1,453 km, then Delhi-Mumbai (A) at 1,419 km, and finally Mumbai-Chennai (B) at 1,290 km, yielding the sequence C, D, A, B.

Explanation

The Rajasthan Semi-Arid Plain, also known as the Rajasthan Bangar, is divided into four distinct physiographic sub-regions: the Luni Basin (Godwar Region), the Shekhawati Region, the Nagaur Uplands, and the Ghaggar Plain. The Luni Basin and Shekhawati region are integral parts of this transitional zone between the Aravalli Range and the Marusthali. The Ghaggar Plain is formed by the seasonal Ghaggar river and is primarily spread across the northern districts of Hanumangarh and Ganganagar. The Nagaur Uplands, situated between the Luni Basin and the Shekhawati region, are characterized by an average elevation of 300 to 500 meters and are notable for their internal drainage systems and the presence of numerous saline lakes such as Didwana, Kuchaman, and Sambhar, which are formed by the accumulation of salts in topographic depressions.

Explanation

The average rainfall in Rajasthan during the southwest monsoon follows a distinct spatial gradient, increasing from the northwest and west toward the east and southeast. Jalor is located in the semi-arid region of western Rajasthan and receives relatively lower rainfall, typically averaging between 400 mm and 500 mm. Moving eastward, Jaipur is situated in the semi-arid to sub-humid eastern plains where the average rainfall increases to approximately 550 mm to 650 mm. Kota lies further southeast in the humid Hadoti region, which is one of the high-rainfall zones of the state, receiving an average of 750 mm to 850 mm. This progression from the arid/semi-arid west to the humid southeast confirms that the sequence of Jalor, Jaipur, and Kota represents a correct ascending order of monsoon precipitation.

Explanation

Kaiga Generating Station is located in the state of Karnataka, specifically in the Uttara Kannada district on the banks of the Kali River. It consists of four indigenous pressurized heavy water reactors operated by the Nuclear Power Corporation of India Limited. Since the plant is situated in Karnataka and not in Tamil Nadu, this pairing is factually incorrect.

Explanation

Alfisols are the predominant soil order found in the semi-arid and sub-humid regions of eastern Rajasthan, covering districts such as Jaipur, Dausa, Alwar, Bharatpur, and Sawai Madhopur. These soils are characterized by a clay-enriched sub-surface horizon known as an argillic horizon and possess a high base saturation, making them naturally fertile and suitable for various crops. They typically form in areas with moderate rainfall where the climate allows for the leaching of some minerals while retaining significant amounts of calcium, magnesium, and potassium. In the eastern plains of Rajasthan, these soils are often associated with alluvial deposits and support intensive agriculture due to their favorable texture and moisture-holding capacity.

Explanation

According to the final estimates of the Ministry of Agriculture and Farmers Welfare for 2021-22, India produced 11.562 million tonnes of bajra. Rajasthan production for the same year stood at 4.507 million tonnes. The state percentage contribution to the national total is calculated using the formula:

Percentage Contribution = (Rajasthan Production)/(All India Production) × 100

Percentage Contribution = 4.507/11.562 × 100 = 38.98

Rajasthan is the leading state in bajra production in India, as the crop is highly drought-tolerant and thrives in the low-rainfall regions and sandy soils characteristic of the state. This contribution reflects Rajasthan status as the top producer, consistently providing more than one-third of the country total pearl millet output.

Explanation

The MedTech Medical Devices Park is a specialized industrial zone established by the Rajasthan Industrial Development and Investment Corporation (RIICO) at Boranada in Jodhpur. This dedicated park was developed to facilitate the manufacturing of medical equipment, surgical instruments, and diagnostic devices within Rajasthan. By providing specialized infrastructure, common facility centers, and testing laboratories, the project aims to attract investment in the healthcare manufacturing sector and reduce the country's reliance on imported medical technology. The choice of Boranada as the site leverages Jodhpur's existing industrial ecosystem and strategic connectivity, fostering a hub for innovation and production in the medical technology field.

Explanation

Khadin is a traditional indigenous water harvesting system designed for arid and semi-arid regions, first developed by the Paliwal Brahmins of Jaisalmer in the 15th century. The system consists of an earthen embankment, known as a bund, constructed across the flow of rainwater runoff from rocky upland catchments. This structure allows rainwater to collect on the low-lying agricultural land, saturating the soil and recharging the local groundwater table. Once the water seeps into the ground or evaporates, the moisture-retaining soil is used to grow crops like wheat and gram during the Rabi season without the need for additional irrigation. This method is particularly prevalent in Jaisalmer due to the district's extremely low rainfall and specific geological conditions that favor such runoff farming.

Explanation

Udaipur is associated with the Som and Jakham rivers as the Som originates from the Bicha Meda hills in the Udaipur district and joins the Jakham and Mahi rivers at the Beneshwar confluence. Bundi is primarily drained by the Kural river, which serves as a significant tributary within the Mez river basin in this region. Bharatpur is characterized by the flow of the Gambhiri and Parwati rivers, which are integral parts of the drainage system in eastern Rajasthan. Alwar is the main region for the Sabi and Ruparil rivers; the Sabi flows through Alwar after originating from the Sewar hills, while the Ruparil, also known as the Barah river, originates from the Udainath hills situated within the Alwar district.

Explanation

Rajasthan is the primary producer of asbestos in India, containing the vast majority of the country's resources, particularly the tremolite and anthophyllite varieties. Arjunpura is a well-known asbestos mining site located in the Ajmer district, while Piperda is a significant deposit site situated in the Pali district. These locations are part of the mineralized belts within the Aravalli mountain range, where asbestos occurs in association with ultramafic rocks and magnesium-rich carbonate rocks that have undergone hydrothermal alteration. The geological environment in these specific areas of Ajmer and Pali provides the necessary conditions for the formation of fibrous silicate minerals that characterize commercial asbestos deposits.

Explanation

The lignite deposits in Rajasthan are primarily found in the Tertiary sedimentary rocks of the Barmer, Bikaner, and Nagaur districts. Kapuri is a significant lignite field located in the Barmer district, contributing to the state's fuel requirements for thermal power. Medata and Kasnau are prominent lignite-bearing areas situated in the Nagaur district, where substantial reserves were formed during the Eocene epoch. These locations represent major components of the Nagaur and Barmer-Sanchore basins, which are the primary geological structures housing Rajasthan's brown coal. The lignite from these regions is characterized by its use in local power generation projects, such as those in Giral and Barsingsar, making these sites central to the state's mineral energy resources.

Explanation

Sorsan is located in the Baran district of Rajasthan. In April 2023, the state government notified Sorsan as a Conservation Reserve to provide a protected habitat for the Great Indian Bustard, Blackbucks, and other wildlife. The administrative and geographic location of this protected area is within Baran, making its pairing with Bundi incorrect.

Explanation

The Godwar Circuit is a significant tourism route designated by the Rajasthan Tourism Department that primarily covers the districts of Pali, Sirohi, and Jalore. Mount Abu, which is Rajasthan's only hill station located in the Sirohi district, and Ranakpur, famous for its magnificent marble Jain temple located in the Pali district, are key destinations within this specific circuit. This administrative classification is designed to promote the unique cultural, religious, and natural heritage of the southwestern Aravalli region, linking the Dilwara temples and Nakki Lake of Mount Abu with the architectural marvels of Ranakpur.

Explanation

The Socialist Party expressed strong reservations regarding the representative nature of the Constituent Assembly, which had been elected indirectly by provincial assemblies based on a restricted franchise under the Cabinet Mission Plan. In March 1948, the National Executive Committee of the Socialist Party passed a resolution demanding the dissolution of the existing Constituent Assembly. The party argued that because the body was not elected through universal adult suffrage, it lacked the democratic legitimacy to frame a constitution for a free and democratic India. They advocated for fresh elections based on adult franchise to ensure that the resulting document truly reflected the aspirations and will of the entire Indian population rather than just the privileged sections who possessed voting rights at the time.

Explanation

According to the 2011 Census data, the overall literacy rate of Rajasthan is 66.1 percent. The sequence of districts in decreasing order of literacy rate begins with Kota, which recorded the highest literacy at 76.6 percent. It is followed by Jaipur with a literacy rate of 75.5 percent. Jhunjhunu ranks third in the state at 74.1 percent, while Sikar and Alwar follow with 71.9 percent and 70.7 percent respectively. These districts represent the highest educational attainment levels in the state, primarily concentrated in the eastern and northeastern regions.

Explanation

The Constitution of India distinguishes between fundamental rights granted to any person (including foreigners and legal entities) and those reserved exclusively for Indian citizens. The specific group of rights restricted solely to citizens includes Articles 15, 16, 19, 29, and 30. Article 15 prohibits discrimination against citizens on grounds of religion, race, caste, sex, or place of birth. Article 16 provides equality of opportunity for citizens in public employment. Article 19 guarantees six basic freedoms, including speech, assembly, and movement, which are accessible only to citizens. Article 30 grants minorities the right to establish and administer educational institutions, a collective right interpreted within the framework of protections for Indian citizens. These provisions ensure that certain political and civil privileges are maintained specifically for the members of the Indian polity.

Explanation

The provision for free legal aid was incorporated into the Constitution of India through the 42nd Amendment Act of 1976. This amendment inserted Article 39A into the Directive Principles of State Policy, which explicitly mandates that the State shall provide free legal aid by suitable legislation or schemes to ensure that opportunities for securing justice are not denied to any citizen by reason of economic or other disabilities. The objective of this article is to promote justice on the basis of equal opportunity and to ensure that the legal system functions in a manner that promotes social and economic justice for the marginalized sections of society. To give effect to this constitutional directive, the Legal Services Authorities Act was later enacted in 1987.

Explanation

Indira Gandhi vs. Raj Narain (1975) challenged the 39th Amendment Act, which inserted Article 329A to place the election of the Prime Minister and the Speaker outside the jurisdiction of the courts.

Minerva Mills vs. Union of India (1980) challenged the 42nd Amendment Act, specifically those sections that attempted to give Directive Principles precedence over Fundamental Rights and limit the scope of judicial review.

Kihoto Hollohan vs. Zachillu (1992) challenged the 52nd Amendment Act, known as the Anti-Defection Law, which introduced the Tenth Schedule to the Constitution to curb political defections.

P. Sambamurthy vs. State of Andhra Pradesh (1987) challenged the 32nd Amendment Act, which inserted Article 371-D to provide special provisions for the state of Andhra Pradesh regarding public employment and education.

Explanation

Under Article 55 of the Constitution of India, the value of the vote of an elected member of a State Legislative Assembly (MLA) is determined by a specific formula to ensure uniformity among states. The population of the state is divided by the total number of elected members of the Legislative Assembly, and the resulting quotient is further divided by 1,000. The formula is: Value of vote of an MLA = Total population of the State / (Total number of elected members of the Assembly × 1000) If, after dividing by 1,000, the remainder is 500 or more, then the value of the vote is increased by one. The statement is incorrect because it uses the divisor of hundreds instead of thousands, which does not align with the constitutional requirement for calculating the electoral weight of an MLA.

Explanation

The Election Commission of India exercises advisory jurisdiction under Articles 103 and 192 of the Constitution. When a question arises as to whether a sitting member of Parliament or a State Legislature has become subject to any disqualification (other than those under the Tenth Schedule), the President or the Governor must refer the matter to the Election Commission for its opinion. The Constitution mandates that the President or the Governor shall act according to the opinion rendered by the Commission, making its advice binding in these quasi-judicial matters. This ensures that the determination of disqualification is handled by an independent constitutional authority.

Explanation

The Speaker of the Lok Sabha is vested with specific constitutional powers that ensure the smooth functioning of the lower house and its coordination with the upper house. Under Article 118(4), the Speaker presides over the joint sitting of both the Lok Sabha and the Rajya Sabha, which is summoned by the President to resolve deadlocks on bills. In the legislative process, the Speaker exercises the power to certify the nature of financial legislation; specifically, under Article 110, the Speaker determines whether a bill is a Money Bill before it is transmitted to the Rajya Sabha, and this certification is final and binding. Additionally, to maintain the neutrality and impartiality of the office, Article 100(1) stipulates that the Speaker does not vote in the first instance on any matter during the proceedings of the House. Instead, the Speaker possesses and exercises a casting vote only in the event of an equality of votes, serving as a tie-breaker to resolve a deadlock.

Explanation

The Terms of Reference for the 16th Finance Commission, notified by the Ministry of Finance on December 31, 2023, are primarily based on the constitutional requirements under Article 280. The commission is mandated to make recommendations on the distribution of net tax proceeds between the Union and the States, the principles governing grants-in-aid to the States from the Consolidated Fund of India, and measures to augment the Consolidated Fund of States for the benefit of Panchayats and Municipalities. Although the Commission is specifically asked to review the present arrangements for financing disaster management initiatives with reference to the Disaster Management Act of 2005, the mandate does not extend to a review of the existing mechanisms for financing climate management initiatives. The official notification focuses on core fiscal federalism and disaster-related funding rather than broader climate finance frameworks.

Explanation

In the 2004 General Elections for the 14th Lok Sabha, the Indian National Congress (INC) emerged as the single largest party by winning 145 seats. This victory enabled the formation of the United Progressive Alliance (UPA) government under the leadership of Manmohan Singh. The official data from the Election Commission of India confirms that the Bharatiya Janata Party (BJP) secured 138 seats, while the Communist Party of India (Marxist) won 43 seats. Because the seat counts provided in statements (b) and (c) deviate from these historical records, only statement (a) is factually accurate.

Explanation

The Central Vigilance Commission (CVC) was created by the Government of India in 1964 following the recommendations of the Committee on Prevention of Corruption, popularly known as the Santhanam Committee. Chaired by K. Santhanam, this committee was constituted in 1962 to suggest measures for checking corruption in the administration and to provide a high-level body for investigating and preventing misconduct among public servants. Initially established through an executive resolution, the CVC was later accorded statutory status in 2003 under the Central Vigilance Commission Act, following directives from the Supreme Court in the Vineet Narain case. It functions as an independent apex body responsible for monitoring all vigilance activities under the Central Government and advising various authorities on planning, executing, and reforming their vigilance work.

Explanation

Bhairon Singh Shekhawat was the Chief Minister of Rajasthan when President's Rule was imposed on two separate occasions, the highest number for any leader in the state. The first instance occurred in February 1980 when his Janata Party government was dismissed by the central government. The second instance took place in December 1992, when his Bharatiya Janata Party government was dismissed following the events in Ayodhya. Rajasthan has come under President's Rule a total of four times since its formation, and Shekhawat is the only Chief Minister to have seen his tenure interrupted twice by the invocation of Article 356.

Explanation

The Rajasthan Council of Ministers, established under Chief Minister Bhajan Lal Sharma following the 2023 assembly elections, contains two women members. Diya Kumari holds the office of Deputy Chief Minister and manages significant portfolios including Finance, Tourism, and the Public Works Department. Manju Baghmar serves as a Minister of State, with responsibilities in the Women and Child Development and Public Works departments. This administrative composition remained unchanged through the end of November 2024.

Explanation

The Committee on Subordinate Legislation in the Rajasthan Legislative Assembly is governed by Rules 243, 244, and 245 of the Rules of Procedure and Conduct of Business of the Rajasthan Legislative Assembly. Rule 243 provides for the constitution of the committee, while Rule 244 outlines its functions to scrutinize and report to the Assembly whether the powers to make rules, regulations, and bye-laws delegated by the Legislature or conferred by the Constitution are being properly exercised within the scope of such delegation. Rule 240 of the Assembly rules specifically pertains to the functions of the Committee on Public Undertakings. Consequently, the assertion that the Committee on Subordinate Legislation is governed by Rule 240 is inaccurate under the established procedural rules of the House.

Explanation

Gurumukh Nihal Singh served as the inaugural Governor of Rajasthan, but the date associated with his appointment in the statement is factually inaccurate. Although he assumed the office and took the oath on November 1, 1956, his official appointment by the President of India took place on October 25, 1956. The transition from the post of Rajpramukh to Governor occurred following the implementation of the States Reorganisation Act and the Seventh Constitutional Amendment. In legal and constitutional terms, the date of appointment refers to the issuance of the warrant by the President, which preceded the date on which he formally entered upon the office.

Explanation

In Rajasthan, the District Planning Committee is constituted under Section 121 of the Rajasthan Panchayati Raj Act, 1994, to consolidate the plans prepared by the Panchayati Raj Institutions and Municipalities. The Zila Pramukh, who is the elected head of the Zila Parishad or District Council, serves as the ex-officio Chairman of this committee. This setup ensures that the decentralized planning process is led by an elected representative, as envisioned under Article 243ZD of the Constitution of India. The committee typically consists of twenty-five members, including elected representatives from rural and urban local bodies, and is responsible for preparing a draft development plan for the district by considering integrated infrastructure, resource sharing, and spatial planning.

Explanation

The Jaipur Development Authority was established by the Government of Rajasthan under the Jaipur Development Authority Act, 1982 (Act No. 25 of 1982). This legislation was enacted to provide for the establishment of an Authority for the purpose of planning, coordinating, and supervising the proper development of the Jaipur region. The Act received the assent of the Governor on October 12, 1982, and was designed to address the growing needs of urban infrastructure and organized expansion in the state capital, effectively replacing the previous urban improvement trust structure with a more comprehensive statutory body.

Explanation

The movement for rural local self-governance in the Rajasthan region began well before independence, with several princely states enacting specific legislation to formalize village councils. Jaipur passed the Jaipur Village Panchayat Act in 1944 to streamline rural administration. Jodhpur enacted the Marwar Village Panchayat Act in 1945, while Udaipur, the seat of the Mewar state, introduced the Mewar Gram Panchayat Act in 1940. Sirohi also passed its respective Panchayat Act in 1947. These bills provided a legal basis for the formation of Panchayats, granting them certain administrative and judicial powers at the grassroots level long before the unified Rajasthan Panchayat Act was formulated in the post-independence era.

Explanation

Article 320 of the Constitution of India defines the functions and duties of the Public Service Commissions for both the Union and the States. Specifically, Article 320(3)(c) mandates that the State Public Service Commission, which in this context is the Rajasthan Public Service Commission, shall be consulted on all disciplinary matters affecting a person serving under the Government of a State in a civil capacity. This requirement covers various disciplinary actions, including memorials or petitions relating to such matters, to ensure that personnel decisions are made with independent oversight. Although the Governor of a State has the power to make regulations specifying certain matters where such consultation is not necessary, the foundational constitutional provision for mandatory consultation on disciplinary cases is established under this article.

Explanation

Premil Kumar Mathur, a senior judicial officer belonging to the Rajasthan Higher Judicial Service cadre, was appointed as the Registrar General of the Rajasthan High Court, Jodhpur. According to the official administrative notifications and records of the Rajasthan High Court, he formally assumed the charge of this office on April 20, 2024. The Registrar General acts as the chief administrative authority of the High Court registry, overseeing judicial administration and coordinating between the judiciary and various government departments.

Explanation

The Rajasthan Lokayukta and Upa-Lokayukta Act, 1973, defines the scope of the Lokayukta's jurisdiction primarily through the investigation of allegations and grievances related to administrative actions. According to Section 7, the Lokayukta investigates matters involving corruption, misuse of official position for personal gain, and maladministration that causes unnecessary loss or hardship. Issues involving sexual harassment of women, caste discrimination, and violence against children are specialized criminal offenses governed by the Bharatiya Nyaya Sanhita, the Scheduled Castes and the Scheduled Tribes (Prevention of Atrocities) Act, 1989, and the POCSO Act. These matters are investigated by the police and adjudicated by the criminal courts, falling outside the administrative and anti-corruption mandate provided to the Lokayukta under the 1973 Act.

Explanation

According to the rules prescribed by the State Election Commission for Municipal Corporation elections, a candidate belonging to the general category must submit a security deposit of ₹30,000 to contest for the post of Mayor. This financial prerequisite is mandatory at the time of filing nomination papers and is intended to maintain the sanctity of the electoral process by discouraging non-serious candidates. Candidates from reserved categories, including Scheduled Castes, Backward Classes, and women, are eligible for a reduced deposit of ₹15,000. The security deposit is forfeited if the candidate fails to poll at least one-sixth of the total valid votes, while it is returned if the candidate meets this threshold or is successfully elected.

Explanation

The appointment of the State Chief Information Commissioner and State Information Commissioners is governed by Section 15(3) of the Right to Information Act, 2005. According to this provision, the Governor makes these appointments based on the recommendation of a committee consisting of the Chief Minister as the Chairperson, the Leader of Opposition in the Legislative Assembly, and a Cabinet Minister nominated by the Chief Minister. The Chief Justice of the High Court is not included in this committee, as the statutory framework for the Information Commission does not provide for judicial representation in the selection process. Instead, the composition focuses on the executive and the leader of the largest opposition party to ensure a balanced selection within the political framework.

Explanation

Justice Nagendra Kumar Jain served as the Chairperson of the Rajasthan State Human Rights Commission from July 16, 2005, to July 15, 2010. Under the provisions of the Protection of Human Rights Act, 1993, which were in effect during his tenure, the Chairperson was appointed for a term of five years or until the age of seventy years, whichever occurred earlier. Justice Jain was the first chairperson in the history of the Rajasthan State Human Rights Commission to complete the full statutory five-year term in office. His tenure was marked by the successful completion of the mandate without early resignation or retirement due to the age limit before the five-year period concluded.

Explanation

The Citizen Charter is an administrative instrument designed to enhance the quality, transparency, and accountability of public service delivery by establishing specific standards and timeframes. Its primary focus is on the operational relationship between service providers and users regarding existing services. Creating a mechanism for the effective hearing of public demands is generally considered a function of the broader democratic and policy-making process, such as public consultations, legislative hearings, or social audits. While a charter incorporates grievance redressal to address failures in promised service levels, the proactive collection and deliberation of general public demands for new policies, infrastructure, or systemic reforms fall outside the specific scope of a service delivery charter.

Explanation

The financial year 2020-21 was characterized by a severe economic shock induced by the COVID-19 pandemic and the associated lockdowns, leading to a significant contraction in India's economic output. According to data from the National Statistical Office (NSO), this was the specific year when the annual growth rates of Gross National Income (GNI) and Net National Income (NNI) turned negative both at constant (2011-12) prices and at current prices. At constant prices, the GNI growth rate was approximately -4.3 percent and the NNI growth rate was approximately -4.8 percent. Unusually, even at current prices, the growth rates were negative, with GNI and NNI recorded at approximately -1.3 percent and -1.8 percent respectively. This occurred because the sharp decline in real production was so substantial that it outweighed the inflationary effects that typically keep nominal growth rates positive. This synchronization of negative growth across both real and nominal measures reflects the unique depth of the economic downturn during the pandemic.

Explanation

The Input Tax Credit (ITC) mechanism is a cornerstone of the Goods and Services Tax (GST) framework designed to eliminate the cascading effect of taxes, commonly known as tax on tax. Under this system, a business can reduce the tax it has already paid on inputs (purchases of goods or services) from the tax it is liable to pay on its output (sales). Mathematically, the net tax liability is calculated as Net Tax Payable = Tax on Output - Input Tax Credit. By allowing this credit, the GST system ensures that tax is levied only on the value added at each stage of the supply chain. This prevents the historical issue where tax paid at an earlier stage became part of the cost of the product, upon which further tax was calculated at the next stage, thus effectively preventing double taxation of the same value.

Explanation

The Raj Nivesh Portal is the digital interface for Rajasthan's Single Window Clearance System, whereas the One Stop Shop (OSS) is a physical institutional facility established at the Bureau of Investment Promotion (BIP). While the Board of Investment (BoI), which provides high-level approvals for large-scale projects, is chaired by the Chief Minister, the OSS facility itself is managed and housed within the BIP. Statement b is incorrect because it conflates the digital portal with the physical OSS facility and incorrectly describes the administrative housing of the OSS as being directly under the Chief Minister instead of the Bureau of Investment Promotion.

Explanation

Headline inflation represents the total inflation within an economy, encompassing all components including food and energy. In contrast, core inflation measures price changes while excluding the volatile food and fuel sectors. Statement C is correct because the prices of food and energy are highly sensitive to seasonal factors, supply chain disruptions, and global commodity market fluctuations. Consequently, the inclusion of these unstable components makes headline inflation significantly more volatile than core inflation, which serves as a more stable indicator of the long-term inflationary trend and underlying demand conditions in the Indian economy.

Explanation

Karnataka (ii) was a leading producer of cereal crops (A) in 2021-22, driven by its high output in coarse cereals and maize. Madhya Pradesh (iii) is traditionally the top producer of total pulses (B) in India, contributing the largest share to the national basket. Gujarat (v) ranked first in the production of mung bean (C) during the 2021-22 agricultural year. Maharashtra (iv) emerged as the top producer of soybean (D), surpassing other states due to high productivity and expanded cultivation area during this specific period.

Explanation

The National Food Security Act (NFSA) was deemed to have come into force on July 5, 2013, which is the date the National Food Security Ordinance was promulgated to provide immediate legal status to the right to food. The Act formally transitioned food security from a welfare-based approach to a rights-based approach. Under the provisions of the legislation, specifically Section 3(2), the Act legally entitles 75 percent of the rural population and 50 percent of the urban population to receive subsidized food grains under the Targeted Public Distribution System. This coverage ensures that nearly two-thirds of the Indian population, amounting to approximately 81.35 crore individuals based on 2011 Census data, has access to essential food grains at highly subsidized prices.

Explanation

India maintained the 126th position out of 143 countries in the World Happiness Report 2024, which is the exact same rank it held in the 2023 report. This stability in ranking over the recent years suggests a period of stagnation in the subjective well-being of the population as measured by the Gallop World Poll. The report assesses happiness using a three-year average of life evaluations based on factors such as GDP per capita, social support, healthy life expectancy, freedom, generosity, and perceptions of corruption. India's consistent placement in the lower quartile of the index reflects that the socio-economic improvements observed in other sectors have not yet resulted in a significant increase in the overall perceived happiness or life satisfaction of its citizens relative to global standards.

Explanation

The ratio of personnel to population, formally known as the Worker Population Ratio (WPR), is an economic indicator used to assess the employment situation within a country. It is defined as the percentage of employed persons in the total population. The ratio is calculated using the formula:

WPR = (Total number of employed persons)/(Total population) × 100

This metric provides an estimate of the proportion of the entire population that is actively involved in the production of goods and services. Because it uses the total population as the denominator, it accounts for all individuals regardless of age or labor force status, offering a broad measure of how much of the human resource base is currently utilized in the economy. It is a key statistic for determining the degree of participation of people in economic activities and for evaluating the capacity of the labor market to provide employment relative to the size of the population.

Explanation

The Fiscal Responsibility and Budget Management (FRBM) Act, enacted in 2003, is a legislative framework specifically designed for fiscal policy and management rather than financial sector reform. Its primary objective is to institutionalize fiscal discipline by setting legal targets for the central government to reduce fiscal and revenue deficits, manage public debt, and ensure long-term macroeconomic stability. While financial sector reforms focus on the regulation, efficiency, and health of banking institutions, insurance, and capital markets, the FRBM Act governs the government's own budgetary processes, expenditure patterns, and borrowing limits. By targeting the sustainability of public finances and transparency in fiscal operations, it serves as a tool for fiscal consolidation and is distinct from reforms aimed at the operational or regulatory framework of the financial services industry.

Explanation

The actual fiscal deficit for Rajasthan in the financial year 2022-23 was recorded at 3.76 percent of the state’s Gross State Domestic Product (GSDP), which validates Statement A. This figure represented an increase from the previous financial year 2021-22, when the fiscal deficit stood at 3.51 percent of GSDP, thereby making Statement C correct. Statement B is incorrect because the Rajasthan Fiscal Responsibility and Budgetary Management Act, 2005, originally set a fiscal deficit target of 3 percent of GSDP. While the Central Government allowed states an enhanced borrowing limit of up to 3.5 percent of GSDP (plus an additional 0.5 percent conditional on power sector reforms) for 2022-23, the actual deficit of 3.76 percent exceeded the standard statutory limit of 3 percent as well as the unconditional limit set for that year.

Explanation

The Rajasthan Mineral Policy 2024 was formulated to align the state's mining sector with the Viksit Rajasthan 2047 vision. Statement A is correct as the policy sets ambitious employment targets to provide jobs to 50 lakh people by 2029-30 and 1 crore people by 2046-47 through direct and indirect mining activities. Statement B is correct because it identifies the current GSDP contribution of the mineral sector at approximately 3.4 percent and sets phased targets to increase this to 5 percent by 2029-30 and further to 8 percent by 2046-47. Statement C is correct as the policy aims to expand the scope of mining operations by increasing the number of minerals under active extraction from the current 58 types to 70 types by 2047, ensuring better utilization of the state's diverse geological resources.

Explanation

Gross Fixed Capital Formation (GFCF) measures the net increase in physical assets such as machinery, equipment, and infrastructure within the state's economy. According to the Rajasthan Economic Review, the Construction sector consistently provides the highest contribution to GFCF due to extensive investments in residential and non-residential buildings, roads, and other civil engineering works. The Manufacturing sector is the second-largest contributor, driven by capital investments in industrial machinery and factory setups. Agriculture, which includes forestry and fishing, follows next as capital is formed through irrigation infrastructure and farm mechanization. The Mining sector, despite Rajasthan's rich mineral resources, typically accounts for a smaller share of total fixed capital formation compared to the broader industrial and construction activities. This sequence reflects the capital-intensive nature of infrastructure development and industrial processing in the state's economic landscape.

Explanation

The Department for Promotion of Industry and Internal Trade (DPIIT), which functions under the Union Ministry of Commerce and Industry, is the nodal agency responsible for issuing the Ease of Doing Business rankings for Indian states and Union Territories. These rankings are based on the Business Reform Action Plan (BRAP) framework, which evaluates states on several parameters such as investment enablers, access to information, labor regulations, and environmental clearances. By assessing the implementation of these reforms, DPIIT aims to foster a competitive spirit among states to improve the regulatory environment and facilitate a more efficient business climate across the country.

Explanation

Under this initiative, families are issued an Aastha card if they have two or more members with a disability certified at 40 percent or higher. This eligibility criterion acknowledges that households with multiple specially-abled members face unique financial and social challenges. Once registered, these families are granted benefits equivalent to those categorized under the Below Poverty Line status, including access to subsidized food grains through the Public Distribution System, medical facilities, and preference in various state government welfare programs.

Explanation

The Chief Minister Swanidhi Yojana in Rajasthan is designed to provide financial assistance and credit support to street vendors operating in urban areas. This scheme facilitates collateral-free working capital loans to help small-scale traders and vendors resume their businesses and achieve economic self-reliance. By providing interest subsidies and credit guarantees, the government ensures that street vendors can access formal banking channels, reducing their dependence on high-interest informal moneylenders. The initiative also incentivizes digital transactions and timely repayments, which helps in building a credit score for the vendors to access higher loan amounts in subsequent tranches.

Explanation

The lens of the eye is primarily composed of water and specialized proteins known as crystallins. These proteins are precisely arranged to maintain the transparency of the lens, allowing light to pass through clearly to the retina. As a person ages, or due to factors like oxidative stress and ultraviolet radiation, these proteins begin to denature and clump together. This process of protein aggregation disrupts the orderly structure of the lens, creating opaque areas that scatter light instead of transmitting it. As these clusters of misfolded proteins grow, they cause the lens to become increasingly cloudy and lose its transparency, which is the defining characteristic of a cataract.

Explanation

Pressure is defined as the physical force exerted on an object per unit area. All the listed terms are valid units of pressure used across different scientific and engineering disciplines. The Pascal (Pa) is the SI unit of pressure, defined as one Newton per square meter (1 Pa = 1 N/m²). The bar is a metric unit commonly used in meteorology and hydraulics, equal to exactly 10⁵ Pa, which is approximately the atmospheric pressure on Earth at sea level. The atmosphere (atm) is a reference unit originally defined as the pressure exerted by the air at sea level, standardized as 101,325 Pa. The torr is a unit based on the Millimeter of Mercury scale, where 1 torr is defined as exactly 1/760 of a standard atmosphere (1 atm = 760 torr), frequently utilized in vacuum physics and medicine.

Active Electronically Scanned Array (AESA) radars utilize an array of hundreds or thousands of individual solid-state Transmit/Receive (T/R) modules. Each of these modules functions as an independent radar element that can be individually controlled for phase, frequency, and amplitude. This architectural design allows the radar system to generate multiple independent beams simultaneously and steer them electronically at near-instantaneous speeds without physical movement of the antenna. Consequently, AESA radars are highly proficient at multitasking, enabling them to track a large number of targets concurrently while simultaneously performing other mission tasks such as searching, fire control, and terrain mapping. This high-capacity multi-target tracking is a defining operational feature of modern AESA systems.

Explanation

Fourth generation biofuels represent an advanced stage of bioenergy technology that combines the use of genetically modified microorganisms with carbon capture and storage techniques. This generation specifically utilizes genetically engineered algae, which are tailored through synthetic biology and metabolic engineering to maximize their lipid production and growth rates. These modified algae act as biological carbon-sequestration systems, converting solar energy and CO₂ directly into energy-rich molecules or fuels such as hydrogen and synthetic gasoline. By manipulating the metabolic pathways of algae, scientists can create strains that secrete fuels directly into their growth medium, simplifying the extraction process and significantly increasing the overall energy yield compared to traditional biofuel sources. This approach aims to create a carbon-negative fuel cycle while avoiding the use of arable land and fresh water resources.

Explanation

Artificial Intelligence is the broad field of creating systems capable of performing tasks that typically require human intelligence. Machine Learning is a specific subset of Artificial Intelligence that focuses on the development of algorithms that allow computers to learn from and make predictions or decisions based on data. It represents the transition from rule-based programming to data-driven learning.

Reinforcement learning is a distinct type of machine learning where an agent learns to behave in an environment by performing certain actions and observing the results. The process is characterized by a trial and error approach where the system seeks to maximize a cumulative reward signal. When the machine performs a task successfully or makes a move that leads toward the goal, it receives a positive reward, which reinforces that specific behavior for future iterations.

Explanation

Kwashiorkor is a severe form of protein-energy malnutrition caused by a significant deficiency in dietary protein. Although the individual may consume enough calories from carbohydrates, the lack of high-quality protein prevents the body from maintaining essential functions like tissue repair and fluid balance. This deficiency leads to a drop in serum albumin levels, which decreases the osmotic pressure of the blood. Consequently, fluid leaks from the intravascular space into the interstitial tissues, resulting in the characteristic edema or swelling of the abdomen and extremities. Other clinical manifestations include stunted growth, thinning and discolored hair, and skin lesions. Kwashiorkor typically occurs in children who are weaned from breast milk onto a diet high in starch but low in protein.

Explanation

Sucralose is a trichloro derivative of sucrose that exhibits a sweetness intensity approximately 600 times that of regular cane sugar. It is chemically synthesized by the selective chlorination of sucrose, replacing three hydroxyl groups with chlorine atoms. This modification results in a molecule that is not metabolized by the body for energy, making it a zero-calorie sweetener. Sucralose is highly favored in the food industry because it remains stable at high temperatures, allowing it to be used in baking and cooking, and it possesses a taste profile that very closely resembles natural sugar without a bitter aftertaste. Among the artificial sweeteners listed, it has the highest relative sweetness value compared to sucrose.

Explanation

Iodine is classified as a trace mineral, also known as a micromineral, because the human body requires it in very small amounts, generally less than 100 milligrams per day. It is an essential component of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), which are vital for regulating metabolic rate, protein synthesis, and proper neurological development. Within the body, iodine is primarily concentrated in the thyroid gland, but it is also present and functional in various fluids and tissues, including the blood, salivary glands, and gastric mucosa.

Explanation

Chikungunya is a viral disease caused by the Chikungunya virus (CHIKV), which is an RNA virus belonging to the genus Alphavirus in the family Togaviridae. It is transmitted to humans primarily through the bite of infected Aedes aegypti and Aedes albopictus mosquitoes. Because the causative agent is a virus and not a bacterium, the combination of Chikungunya and bacteria is incorrect.

Explanation

The Central Pollution Control Board (CPCB) defines the National Air Quality Index (AQI) using six distinct categories based on ambient concentration values of air pollutants and their likely health impacts. The Moderate category specifically corresponds to the index value range of 101 to 200. Air quality in this range is associated with breathing discomfort for people with lungs, asthma, and heart diseases. The calculation of this index considers eight pollutants—PM₁₀, PM₂.₅, NO₂, SO₂, CO, O₃, NH₃, and Pb—for which short-term National Ambient Air Quality Standards are prescribed. The Moderate classification acts as a secondary tier in the index, indicating a level of pollution that requires caution for sensitive groups.

Explanation

El Niño and La Niña are large-scale ocean-atmosphere climate patterns that represent the warm and cool phases of the El Niño-Southern Oscillation (ENSO) cycle. These phenomena involve periodic fluctuations in sea surface temperatures and atmospheric pressure across the central and eastern tropical Pacific Ocean. In contrast, a cyclone is a specific, localized weather system characterized by a low-pressure center and strong winds rotating inward. While El Niño and La Niña can significantly influence the frequency, intensity, and location of tropical cyclones globally by altering atmospheric conditions like wind shear and sea surface temperatures, they are broad climatic oscillations rather than individual storm systems.

Explanation

As the institute is the premier body for cotton technology in India, this development focuses on adding value to cotton by-products, commonly referred to as Kapas in various Indian languages.

Explanation

The IUCN Red List of Threatened Species is widely referred to as the Barometer of Life because it provides a comprehensive and objective assessment of the health of the world's biodiversity. Much like a meteorological barometer measures atmospheric pressure to predict weather changes, the Red List tracks the extinction risk of species to gauge the status of the natural world and the impact of human activities on ecosystems. Established in 1964, it uses standardized, science-based criteria to evaluate thousands of species, identifying those at highest risk of disappearing. This information is critical for informing conservation priorities, influencing international policy, and guiding the allocation of resources to protect biological diversity globally.

Explanation

The Rajasthan Forestry and Biodiversity Project (Phase-2), which commenced in 2011 with financial assistance from the Japan International Cooperation Agency (JICA), specifically covers 15 districts of the state rather than 18. These 15 districts include 10 desert districts (Jaisalmer, Barmer, Jodhpur, Bikaner, Jalore, Pali, Nagaur, Churu, Jhunjhunu, and Sikar) and 5 non-desert districts (Banswara, Dungarpur, Sirohi, Udaipur, and Bhilwara). Additionally, the project focuses on the conservation and management of 7 wildlife sanctuaries, which are Kumbhalgarh, Raoli-Todgarh, Sitamata, Mount Abu, Phulwari-ki-Nal, Jaisamand, and Bassi, making the mention of 8 wildlife sanctuaries in the statement inaccurate.

Explanation

Ganga is India's first cloned female calf of the Gir breed, born on March 16, 2023. The calf was produced by scientists at the National Dairy Research Institute (NDRI) in Karnal, Haryana, as part of a project to clone high-yielding indigenous cattle breeds. The researchers used somatic cell nuclear transfer (SCNT) technology, where somatic cells from the skin of a high-yielding Gir cow were used to create the clone. This milestone aims to propagate the genetics of superior indigenous breeds to enhance domestic milk production, as the Gir breed is renowned for its high milk yield, resilience to heat, and resistance to tropical diseases.

Explanation

An assumption is an underlying premise that must be true for the statement to be valid. Assumption (I) is not implicit because the recommendation to rotate crops for nutrient fulfillment does not mean that growing the same crop repeatedly is impossible; it only suggests that doing so may be detrimental to soil quality. The statement focuses on a beneficial practice for soil health rather than a literal prohibition on re-planting. Assumption (II) is not implicit because it uses extreme language, asserting that there is absolutely no need for fertilizers if crops are rotated. The statement identifies crop rotation as a necessary method for nutrient replenishment, but it does not claim that this practice satisfies every possible soil requirement or entirely eliminates the utility of external supplements like fertilizers in all agricultural contexts.

Explanation

Aandi village, located in the Jaipur district of Rajasthan, has been designated to become a zero-waste model village through the implementation of advanced green technology. This initiative is part of a specialized pilot project aimed at transforming rural waste management into a sustainable and productive system. The core of this model involves the use of eco-friendly technologies, including the Nisargruna biogas plant technology developed by the Bhabha Atomic Research Centre (BARC), which converts organic waste into nutrient-rich manure and biogas. By focusing on source segregation and the complete scientific processing of solid and liquid waste, Aandi is establishing a circular economy framework where waste is treated as a resource rather than a pollutant. This project serves as a demonstration of how rural areas can achieve environmental sustainability and energy self-reliance using modern scientific interventions.

Explanation

According to Thales's Theorem, any triangle inscribed in a circle with one side as the diameter is a right-angled triangle, where the diameter serves as the hypotenuse. In a circle with n = 8 equally spaced points, the number of diameters that can be formed by connecting opposite points is n/2 = 8/2 = 4.

For each specific diameter, a right-angled triangle can be formed by selecting any of the remaining points on the circle as the third vertex. Since there are 8 points in total and 2 are used to form the diameter, there are 8 - 2 = 6 points available to complete the triangle for each diameter. Therefore, the total number of possible right-angled triangles is the product of the number of diameters and the number of available third vertices, which is 4 × 6 = 24.

Explanation

The terms of the series are determined by the general formula aₙ = n³ + n², where n represents the position of the term in the sequence. Applying this formula to the given terms, we find 1³ + 1² = 2 for the first term, 2³ + 2² = 12 for the second term, 3³ + 3² = 36 for the third term, 4³ + 4² = 80 for the fourth term, and 5³ + 5² = 150 for the fifth term. To find the next term in the series (n = 6), we calculate 6³ + 6², which equals 216 + 36 = 252. This pattern can also be expressed as n²(n + 1), which for the sixth term yields 6²(6 + 1) = 36 × 7 = 252.

Explanation

The code system follows a two-step logic: first, the middle letter of the word is removed, and second, the remaining letters are arranged in alphabetical order.

For the word PROJECT, which contains seven letters, the middle letter is J (the 4th letter). Removing J leaves the letters P, R, O, E, C, and T. When these remaining letters are arranged in alphabetical order, they form the code CEOPRT.

For the word PLANE, which contains five letters, the middle letter is A (the 3rd letter). Removing A leaves the letters P, L, N, and E. Arranging these alphabetically results in the code ELNP.

Applying this logic to the word ORGANISED, which consists of nine letters: Identify the middle letter: The 5th letter of O-R-G-A-N-I-S-E-D is N. Remove the middle letter: This leaves the letters O, R, G, A, I, S, E, and D. Arrange alphabetically: A (1) D (4) E (5) G (7) I (9) O (15) R (18) S (19)

Following these steps, the sequence becomes ADEGIORS.

Explanation

Let point A be the origin (0, 0) on a Cartesian plane. Walking 20 meters south to point B places B at (0, -20). Turning left (which is east) and walking 20 meters to point C places C at (20, -20). At point C, Mr. X is facing east. A 45 degree anticlockwise turn from the eastern direction results in a North-East heading.

The displacement from C to D is given by distance d = 20√3 meters at an angle of 45 degrees. The coordinates of D are calculated by adding the components of this displacement to the coordinates of C: x_D = 20 + 20√3 cos 45° = 20 + 20√3 × 1/√2 = 20 + 10√6 y_D = -20 + 20√3 sin 45° = -20 + 20√3 × 1/√2 = -20 + 10√6

The distance from A (0, 0) to D (x_D, y_D) is found using the distance formula AD = √(x_D² + y_D²). AD² = (20 + 10√6)² + (-20 + 10√6)² Using the algebraic identity (a+b)² + (a-b)² = 2(a² + b²), where a = 10√6 and b = 20: AD² = 2((10√6)² + 20²) = 2(600 + 400) = 2(1000) = 2000 AD = √2000 = √(400 × 5) = 20√5 meters

Explanation

The English alphabet consists of 26 letters, out of which 5 are vowels (A, E, I, O, U) and 21 are consonants (B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, and Z). A mirror image of a capital letter is similar to its original shape only if the letter possesses vertical symmetry. Among the 21 consonants, there are 7 letters that have vertical symmetry: H, M, T, V, W, X, and Y. These 7 letters remain unchanged when viewed in a mirror. To find the number of consonants whose images are not similar to their original shape, we subtract the number of vertically symmetrical consonants from the total number of consonants. Using the formula: Non-symmetrical Consonants = Total Consonants - Symmetrical Consonants, we get 21 - 7 = 14. These 14 consonants are B, C, D, F, G, J, K, L, N, P, Q, R, S, and Z.

Explanation

The family tree is established from the given clues in sequence. F is the mother of E, making E a child of F in the first filial generation. D is also a daughter of F, so D and E are siblings in that same generation. A is the daughter of E, placing A one generation below E. C is the son of A, placing C one generation below A. B is married to C, forming the first of the two married couples. This creates a four-generation chain: F (great-grandmother) at the top, E and D as F’s children, A as E’s child, and C as A’s child with B as C’s spouse. In this chain, E is the grandparent of C, and C is therefore the grandchild of E. F is C’s great-grandmother, and C is F’s great-grandchild. D is E’s sibling and therefore A’s aunt and C’s great-aunt. B is the husband of C and son-in-law of A.

Explanation

In the initial 1000 ml mixture, the ratio of milk to water is 3:1. The volume of milk is (3/4) × 1000 = 750 ml and the volume of water is (1/4) × 1000 = 250 ml. The homemaker then adds 250 ml of another mixture with a milk-to-water ratio of 3:2. In this addition, the milk volume is (3/5) × 250 = 150 ml and the water volume is (2/5) × 250 = 100 ml.

The combined mixture has a total volume of 1000 + 250 = 1250 ml. The total milk in this combination is 750 + 150 = 900 ml, and the total water is 250 + 100 = 350 ml. The proportion of milk in the combined mixture is 900 / 1250 = 18/25. After using 250 ml for yogurt, the volume of the remaining mixture is 1250 - 250 = 1000 ml. Since the mixture is uniform, the proportion of milk remains the same. The amount of pure milk left is (18/25) × 1000 = 18 × 40 = 720 ml.

Explanation

When the price of an item decreases while the total expenditure remains constant, the money saved due to the price drop is used to purchase the additional quantity. The total expenditure in this case is ₹ 1,000 and the price reduction is 21%.

The amount of money saved because of the price reduction is calculated as: Savings = 21% of 1,000 = 21/100 × 1,000 = ₹ 210

This saving of ₹ 210 enables the purchase of an additional 10.5 kg of rice. The current price per kg, which is the price after the decrease, is found by dividing the total savings by the extra quantity obtained: Reduced Price per kg = Total Savings / Extra Quantity = 210 / 10.5

To solve this, remove the decimal from the denominator: (210 × 10) / 105 = 2100 / 105 = 20

The price of rice per kg after the 21% decrease is ₹ 20.

Explanation

The annual interest rate R is determined using the simple interest formula SI = (P · R · T)/100. Substituting the given values, 3600 = (8000 · R · 3)/100, which simplifies to 3600 = 240R. Solving for R gives an annual rate of 15%.

When interest is compounded 8-monthly over a period of 2 years (24 months), the number of compounding cycles n is calculated as 24/8 = 3. The interest rate for each 8-month period r is adjusted from the annual rate as r = 15% · 8/12 = 10%.

The total compound interest CI can be found using the formula CI = P · [(1 + r/100)ⁿ - 1]. Substituting the values: CI = 8000 · [(1 + 10/100)³ - 1] CI = 8000 · [(1.1)³ - 1] CI = 8000 · [1.331 - 1] CI = 8000 · 0.331 = 2648

Explanation

The sides of the triangle are 5, 12, and 13 units. Since these values satisfy the Pythagorean theorem, 5² + 12² = 25 + 144 = 169 = 13², the triangle is right-angled. The area of a right-angled triangle is given by Area = 1/2 × base × height. Substituting the legs of the triangle, the area is 1/2 × 5 × 12 = 30 square units.

The area of the rectangle is equal to the area of the triangle, so the rectangle area is 30 square units. The area of a rectangle is also defined as length × width. Given that the width is 10 units, we find the length by solving 10 × length = 30, which gives a length of 3 units.

The perimeter of a rectangle is calculated using the formula P = 2 × (length + width). Substituting the known dimensions, P = 2 × (3 + 10) = 2 × 13 = 26 units.

Explanation

The correct mean is determined by adjusting the initial sum of observations based on the difference between the incorrect and correct values. The initial sum of the 100 observations is calculated as: Sumₒₗ₀ = Meanₒₗ₀ × n = 49 × 100 = 4900

The sum of the values wrongly recorded is 40 + 20 + 50 = 110. The sum of the actual observations is 60 + 70 + 80 = 210. To find the correct sum, subtract the incorrect values and add the correct ones: Sumₙₑᵥ = 4900 - 110 + 210 = 4900 + 100 = 5000

The correct mean is then found by dividing the new sum by the total number of observations: Meanₙₑᵥ = Sumₙₑᵥ/n = 5000/100 = 50

A quicker approach is to calculate the change in the mean directly. The net increase in the total sum is 210 - 110 = 100. Distributed across 100 observations, this results in an increase of 100 / 100 = 1 per observation. Therefore, the corrected mean is 49 + 1 = 50.

Explanation

To find the number of five-letter words where at least one letter is repeated, we use the complement method: subtract the number of words with no repeated letters from the total possible number of words.

The total number of five-letter words that can be formed using 10 distinct letters, where each position can be filled by any of the 10 letters (allowing repetition), is given by: Total = 10⁵ = 100,000

The number of five-letter words where no letters are repeated is calculated by choosing and arranging 5 distinct letters out of 10, which is the number of permutations P(10, 5): No Repetition = 10 × 9 × 8 × 7 × 6 = 30,240

The number of words with at least one letter repeated is the difference between these two values: At Least One Repeated = 100,000 - 30,240 = 69,760

Explanation

The total number of outcomes when two dice are thrown is n(S) = 6 × 6 = 36. The sum of the numbers on the two dice can range from 2 to 12. The prime numbers within this range are 2, 3, 5, 7, and 11.

To find the total number of favorable outcomes, we count the ways to obtain each prime sum. A sum of 2 is obtained in 1 way: (1, 1). A sum of 3 is obtained in 2 ways: (1, 2) and (2, 1). A sum of 5 is obtained in 4 ways: (1, 4), (2, 3), (3, 2), and (4, 1). A sum of 7 is obtained in 6 ways: (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), and (6, 1). A sum of 11 is obtained in 2 ways: (5, 6) and (6, 5).

The total number of favorable outcomes is n(E) = 1 + 2 + 4 + 6 + 2 = 15. The probability is calculated using the formula P(E) = n(E)/n(S). Substituting the values yields P(E) = 15/36, which simplifies to 5/12 after dividing both the numerator and the denominator by 3.

Explanation

In the Rajasthan Assembly by-elections held in November 2024 for seven seats, the Jhunjhunu constituency recorded the highest number of service-employed voters. This is consistent with the demographic profile of the Jhunjhunu and Shekhawati region, which has a significantly high representation of residents in the armed forces and central services. These service voters utilize the Electronically Transmitted Postal Ballot System (ETBPS). While the Kheeversar constituency was notable for its intense political contest and high overall voter engagement, it did not lead the state in the specific category of service-employed ballots. The administrative data from the Election Commission of Rajasthan confirmed that Jhunjhunu remained the primary constituency for service voter participation during this election cycle.

The Union Cabinet, chaired by the Prime Minister, approved the conferment of classical language status to five additional languages in October 2024. These five new additions are Marathi, Pali, Prakrit, Assamese, and Bengali. Before this inclusion, there were six languages recognized as classical: Tamil (2004), Sanskrit (2005), Telugu (2008), Kannada (2008), Malayalam (2013), and Odia (2014).

Explanation

The Major Atmospheric Cherenkov Experiment (MACE) telescope at Hanle, Ladakh, was inaugurated in October 2024 by Ajit Kumar Mohanty, the Chairman of the Atomic Energy Commission and Secretary of the Department of Atomic Energy. This project represents a significant milestone in indigenous scientific development, as the telescope was designed and constructed by the Bhabha Atomic Research Centre (BARC) in coordination with the Electronics Corporation of India Limited (ECIL) and several other Indian industrial collaborators. While the MACE telescope is the largest in Asia and the highest of its kind in the world, it is located at an altitude of approximately 4270 meters above sea level at the Indian Astronomical Observatory site. The assertion of an altitude of 5100 meters is incorrect, which confirms that only the first and third statements are factual.

Explanation

Thomas Holbein Hendley, a British surgeon and archaeologist who contributed extensively to the study of Jaipur state history, identified the archaeological site of Nalia Sar near Sambhar as an ancient Buddhist town. During his late 19th-century explorations, Hendley discovered a variety of artifacts including terracotta figurines, coins, and pottery that displayed clear Buddhist iconographic and cultural traits. His reports described the mound as the site of a flourishing urban settlement with religious structures and dwellings characteristic of a Buddhist community. These initial findings were later validated by more systematic excavations in the 1930s, which confirmed the existence of a significant historical town with cultural sequences extending from the Mauryan period through the Kushana and Gupta eras.

Explanation

Rao Chunda was a significant ruler of the Rathore dynasty who established the foundation of the Marwar kingdom in the late 14th and early 15th centuries. A major turning point in his career was the acquisition of Mandore. During this period, the Inda branch of the Pratihars held Mandore but faced constant threats from the local governors of the Delhi Sultanate. Unable to defend the strategic fort on their own, the Indas entered into a matrimonial alliance with Rao Chunda. As part of this arrangement, they gave Mandore to him in dowry, a historical event often described as the Mandore Dahej or Dahanj. This gift of the fort allowed the Rathores to move their capital from Khed to the more secure and prestigious Mandore, marking the rise of the Rathores as a major power in Rajasthan.

Explanation

The literary work Rao Jaitasi Ro Chhand, authored by the poet Bitthu Suja in the Dingal language, provides a historical account of the conflict between the Rathore ruler Rao Jaitasi of Bikaner and the Mughal prince Kamran Mirza. In 1534 AD, Kamran, who was the brother of Emperor Humayun and controlled Kabul and Lahore, invaded the Bikaner state and captured the Bhatner fort. Rao Jaitasi responded by executing a strategic night attack on the Mughal camp. This surprise offensive was successful, resulting in the defeat of Kamran's forces and forcing him to retreat. The text commemorates this victory and serves as an important source for the early sixteenth-century history of the Bikaner region.

Explanation

The excavation of Ojhiana, an ancient site of the Ahar (Banas) culture located in the Bhilwara district of Rajasthan, was conducted by the Archaeological Survey of India (ASI). The project was carried out during two field seasons between 1999 and 2001. B. R. Meena and Alok Tripathi led the excavation team that explored this unique hilly Chalcolithic settlement. Their work uncovered significant findings, including white-painted black and red ware pottery and numerous terracotta bull figurines, which helped clarify the expansion and regional variations of the Ahar culture in the Banas river basin.

Explanation

The Bijolia movement gained widespread national attention through the support of the nationalist press across India. Along with the Kanpur-based newspaper Pratap, journals such as Abhyuday published from Prayag and Bharat Mitra published from Calcutta were instrumental in regularly reporting on the struggles and grievances of the Bijolia peasants against the oppressive tax system and forced labor imposed by the Thikana. This media campaign helped mobilize public opinion and brought a local agrarian issue to the forefront of the national political discourse. Statement A is incorrect because the pivotal meeting where Vijay Singh Pathik informed Mahatma Gandhi about the movement, leading Gandhi to send his secretary Mahadev Desai to investigate the conditions in Bijolia, occurred in Bombay in 1919 rather than in Wardha.

Explanation

The S. A. Sudhakar (frequently cited in historical records as S. A. Sudhalkar) report of 1945 is associated with the Princely State of Jodhpur. During the mid-1940s, the Marwar Praja Mandal and other political activists in Jodhpur intensified their demands for responsible government and democratic reforms. To address these demands and outline a path for constitutional advancement, the Jodhpur State administration appointed S. A. Sudhalkar, who was a distinguished legal authority and served as the Chief Justice of the Jodhpur High Court. The report he submitted in 1945 proposed a new constitutional framework for the state, which included recommendations for the establishment of a representative legislative body and the devolution of certain administrative powers, reflecting the transition toward a more modern governance structure in the Marwar region.

Explanation

The Walterkrit Rajputra Hitkarini Sabha was established specifically to address and rectify social evils prevalent within the Rajput community of Rajasthan. Its primary focus was on reducing the extravagant expenditures associated with marriages and funeral feasts, which often led to heavy indebtedness and the practice of female infanticide among the Rajput nobility. The organization also formulated rules regarding the minimum age of marriage for Rajput boys and girls. While the Sabha targeted reforms involving the Rajputs and the Charans or Bhats who received ritual gifts called Tyag, it did not include any provisions or objectives for the reformative work of Dalits. The scope of the assembly was strictly limited to the social structure and customs of the Rajput aristocracy and did not extend to the Scheduled Castes or Dalit communities of the region.

Explanation

Mathanadeva was a ruler of the Gurjara-Pratihara lineage who governed the region of Rajyapura, known today as Rajorgarh in the Alwar district of Rajasthan. In the 10th century, specifically around 959 AD (Vikram Samvat 1016), he commissioned the construction of the Nilkantha Mahadeva temple. This architectural masterpiece is dedicated to Shiva, worshipped there in his form as Nilkantha. The Rajorgarh inscription found at the site explicitly mentions Mathanadeva as the builder and records the endowment of village revenues for the rituals and maintenance of the temple. The structure is a significant example of the Pratihara style of temple architecture, featuring a sanctum and elaborate carvings typical of the era.

Explanation

The Chautara, also commonly known as the Tandoora, Nishan, or Veena in various parts of Rajasthan, is a traditional stringed instrument classified as a Tat Vadya. As the name suggests, derived from Chau meaning four and Tara meaning strings, the instrument is characterized by having four metal strings that are plucked to provide a rhythmic and melodic drone. It is constructed with a round wooden resonator and a long fingerless neck.

In the cultural and religious landscape of Rajasthan, the Chautara is fundamentally associated with the devotional music of the Kamad community. It serves as the primary accompaniment for singing the bhajans of the folk deity Baba Ramdevji, often played alongside the Manjira during performances like the Terah Taali dance. The rhythmic plucking of its four strings provides the essential background layer for the choral singing of these sacred hymns.

Explanation

The Khuman Raso is a significant historical work in the Rajasthani language that chronicles the history and lineage of the Guhil dynasty of Mewar, with a primary focus on the valor and reign of Rawal Khuman. This epic poem was authored by Dalpat Vijay. The person paired with it, Karnidan, was a renowned court poet of Maharaja Abhay Singh of Marwar and is best known for composing Suraj Prakash, an account of the Rathore dynasty. Since Karnidan is not the author of Khuman Raso, this pairing is factually incorrect.

Explanation

The Kishangarh painting style is inextricably linked with the artist Nihalchand, who served under Maharaja Sawant Singh and created the iconic Bani Thani, characterized by elongated eyes and sharp features. The Bikaner school of art was pioneered by Ali Raza, a master from Delhi who was brought to the court of Maharaja Karan Singh and established the refined Usta and Mughal-influenced styles. Sahibdin was the preeminent painter of the Mewar school during the 17th century, known for his prolific work on the Ragamala, Rasikapriya, and Bhagvata Purana series under the patronage of Maharana Jagat Singh I. The Marwar school, specifically the Jodhpur branch, features artists like Shivdas, who played a significant role in depicting the royal life and traditional folk themes of the Rathore dynasty.

Explanation

Sant Lal Das was a prominent saint of the Mewat region and the founder of the Laldasi sect. He was a householder saint who lived a married life and had a family, which contradicts the assertion that he remained unmarried. He advocated that one should earn their living through hard work while following the path of devotion.

Following his death in Nagla village, Bharatpur, his remains were brought to Sherpur in Alwar, where his samadhi is located. The Laldasi sect follows the Nirguna Bhakti tradition, which emphasizes the formless divine and rejects idol worship and formal temple structures. Consequently, his memorial at Sherpur is maintained as a sacred samadhi shrine rather than a traditional temple. Because he was married and his memorial is a samadhi site aligned with Nirguna principles rather than a temple, both statements provided are factually incorrect.

Explanation

In the traditional textile culture of Rajasthan, Kamal refers to a distinct shade of bright red that is frequently used in the dyeing and printing of ethnic attire. This color is particularly prominent in the Pomcha, a traditional veil or odhni, where specific hues signify various life events and social statuses. The Kamal color is associated with the vibrant red of a blooming lotus and is widely used in the central motifs and borders of garments crafted through the Bandhani (tie-dye) and block printing techniques. It represents auspiciousness and is a staple in the festive and ceremonial wardrobe of Rajasthani women, reflecting the region's rich heritage of natural dyeing processes.

Explanation

Shobha Ram Kumawat was a prominent political leader from Alwar who served as the Prime Minister of the Matsya Sangh following its formation on March 18, 1948. When the Matsya Sangh was merged into the United State of Greater Rajasthan on May 15, 1949, he was included as a minister in the first state cabinet headed by Chief Minister Hiralal Shastri. In this cabinet, he held the portfolio for Revenue and Agriculture. Regarding the first statement, Shobha Ram Kumawat was born in 1914, which means he was only a child during the Non-Cooperation Movement of 1920-1922. Consequently, he could not have left a legal practice during that period. His active participation in the freedom struggle and his legal career began much later, particularly during the Prajamandal movements of the late 1930s and the Quit India Movement of 1942.

Explanation

In Rajasthani folk literature and oral tradition, the terms Aadi and Hiyali are used to denote riddles. These verbal puzzles are an integral part of the regional heritage, serving as a medium for intellectual entertainment and mental exercise. Aadi usually refers to short, direct riddles, while Hiyali involves more complex, metaphorical descriptions of common objects, natural phenomena, or social situations. The term Hiyali is linguistically linked to the word hiya, meaning heart or mind, indicating that these puzzles are designed to test the listener's wit and deductive reasoning. They are traditionally shared during social gatherings, festivals, and family storytelling sessions to pass on cultural knowledge and linguistic creativity to younger generations.

Explanation

Vima Kadphises, also known as Kadphises II, was the Kushan emperor who significantly expanded the empire into northern India and introduced a standardized gold coinage. He was a devout follower of Lord Shiva, as evidenced by the depictions of Shiva and the Nandi bull on his coins. On these coins, he adopted various high-sounding titles in Kharosthi script, most notably Sarvalokeshwara, which translates to Lord of the Whole World or Lord of the Universe. This title, often paired with Mahishwarasa, highlighted his imperial authority and his religious identity as a devotee of Shiva. The adoption of such grand titles signified the consolidation of Kushan power and the establishment of a centralized, divine-right monarchy in the region.

Explanation

The word Stupa is derived from the Sanskrit language and literally means a heap, pile, or mound. Architecturally, it refers to a structure created through the accumulation of materials like earth, stone, or bricks to form a hemispherical shape. Historically, the practice of erecting such mounds over the ashes or remains of the deceased was a funerary custom in India that predates the Buddhist era. These pre-Buddhist burial mounds, or tumuli, served as memorials for the dead. Buddhism later adopted and refined this existing tradition, transforming the stupa into a sacred architectural symbol used to enshrine the relics of the Buddha or other enlightened teachers, thereby integrating an ancient cultural practice into the core of Buddhist commemorative architecture.

Explanation

Divyavadana is an extensive collection of Buddhist legends and biographical narratives written in Sanskrit. It is associated with the Mulasarvastivada school of Northern Buddhism and contains famous stories such as the Ashokavadana, which details the life and religious contributions of the Mauryan Emperor Ashoka. Aryamanjusri Mulakalpa is a major Mahayana Buddhist text written in Buddhist Hybrid Sanskrit. It is categorized as a Kriya-tantra work and provides a unique historical perspective on India from a Buddhist viewpoint, alongside detailed instructions on rituals, mantras, and the iconography of the Bodhisattva Manjusri.

Explanation

The Ajivika sect, founded by Makkhali Gosala in the 5th century BCE, was anchored in the central philosophy of Niyati, or absolute determinism. This doctrine asserted that every aspect of the universe and the life of every being is entirely governed by fate, leaving no room for the efficacy of human effort, merit, or free will. Furthermore, while the sect believed that destiny was unalterable, its followers practiced extreme asceticism. These rigorous physical penances, which often included severe fasting and social isolation, were viewed not as a means to change one's fate, but as a predetermined stage that individuals must pass through in the final phases of their fixed cycle of cosmic existence before reaching liberation. Historical records from Buddhist and Jain texts describe Ajivika practitioners as following some of the most stringent and difficult ascetic paths of the era.

Explanation

Sher Shah Suri, the founder of the Suri Empire, was a significant patron of architecture during his brief reign from 1540 to 1545. The Tomb of Sher Shah Suri at Sasaram, Bihar, is one of the most distinguished examples of Indo-Islamic architecture. It is an octagonal sandstone structure situated in the middle of a large artificial lake, reflecting a transition from the heavy Lodi style to the more refined Mughal aesthetics. Additionally, Sher Shah commissioned the construction of the Qila-e-Kuhna Masjid in 1541 within the Purana Qila complex in Delhi. This mosque is renowned for its five-bay facade and the use of pointed arches, showcasing an elegant combination of red sandstone and white marble inlay that significantly influenced subsequent Mughal architectural developments.

Explanation

Madhvacharya was the proponent of the Dvaita (Dualism) school of Vedanta and an advocate for Saguna Bhakti, which centers on the devotion to a personal God with attributes. He identified the supreme deity as Lord Vishnu and emphasized that the individual soul and God are eternally distinct entities. Madhvacharya strongly opposed the concept of an impersonal, formless Brahman (Nirguna), instead teaching that salvation could only be achieved through the grace of Vishnu, attained through constant and dedicated worship of his personal form. His philosophy established a clear hierarchy between the Creator and the created, making the worship of the deity in a physical or attribute-based manifestation the core of his spiritual practice.

Explanation

Abanindra Nath Tagore painted the first iconic image of Bharat Mata in 1905 during the Swadeshi movement, which arose in response to the Partition of Bengal. He utilized the visual medium to personify India as a mother figure, aiming to foster a sense of national identity and spiritual unity. In this painting, Bharat Mata is depicted as a four-armed ascetic wearing saffron robes, holding a book, sheaves of paddy, a piece of white cloth, and a rudraksha mala. These objects symbolize the gifts of learning, food, clothing, and spiritual strength, respectively. By portraying the nation as a divine and serene maternal figure, Tagore provided a powerful visual focal point for nationalist sentiment, transforming the abstract concept of the motherland into a tangible symbol of devotion for the Indian independence struggle.

Explanation

Gubbi Mallanarya was a prominent Virashaiva poet who lived during the early 16th century and received patronage from the Vijayanagara Emperor Krishnadevaraya. He authored Bhavichinta Ratna in 1513 and Virashaiva Amruta in 1530, both of which are landmark compositions in the Kannada language. These works utilize the Shatpadi poetic metre, a hallmark of medieval Kannada literature. Bhavichinta Ratna focuses on the stories of legendary Shaiva devotees, while Virashaiva Amruta is a massive hagiographic and philosophical work detailing the lives of various Sharanas and the tenets of the Lingayat faith. His presence in the imperial court signifies the broad linguistic patronage of Krishnadevaraya, who supported Kannada literary excellence alongside his well-known contributions to Telugu literature.

Explanation

The Government of India appointed the Secondary Education Commission in September 1952 under the chairmanship of Dr. Laxman Swami Mudaliar, who was then the Vice-Chancellor of Madras University. Because of his leadership, the body is popularly known as the Mudaliar Commission. The commission was established to examine the existing system of secondary education in India and suggest measures for its reorganization and improvement. Its primary objectives included identifying the problems within the secondary education sector and recommending a curriculum that would cater to the diverse needs of students in the post-independence era, leading to the proposal of multipurpose schools and a three-year secondary and four-year higher secondary system.

Explanation

The Gobi Desert is a vast, cold desert region located in Asia, covering parts of northern China and southern Mongolia. The Patagonia Desert, also known as the Patagonian Steppe, is the largest desert in Argentina, situated in South America. The Great Victoria Desert is the largest desert in Australia, characterized by red sand dunes and salt lakes. The Kalahari Desert is a large semi-arid sandy savanna located in Southern Africa, extending across Botswana, Namibia, and South Africa. Matching these locations to the deserts results in the sequence A-ii, B-iii, C-iv, and D-i.

Explanation

Mediterranean agriculture is restricted to the western margins of continents between 30 and 45 degrees latitude in both hemispheres. Northern Australia is located in the tropical zone, typically between 11 and 20 degrees South latitude, and experiences a tropical savanna climate. This region is characterized by high temperatures year-round and a distinct monsoon-driven summer rainfall pattern. In contrast, Mediterranean agriculture requires a climate defined by mild, wet winters and hot, dry summers. While the southwestern and southern coastal fringes of Australia are prime examples of Mediterranean regions, the northern part of the continent lacks the specific climatic conditions necessary for this type of specialized farming.

Explanation

The liberal phase of the Indian National Movement, led by the Moderates, was deeply rooted in the ideological foundations of Western liberalism. Leaders of this era were products of modern education and held a profound admiration for the democratic institutions, civil liberties, and scientific temper of contemporary Europe, which they sought to introduce in India through constitutional reforms. Simultaneously, these leaders pioneered a sophisticated critique of the colonial economy. Figures like Dadabhai Naoroji, M.G. Ranade, and R.C. Dutt utilized statistical analysis to demonstrate how British policies were causing the systematic drain of wealth from India, leading to chronic poverty and the de-industrialization of the subcontinent. This dual approach of seeking political modernization while exposing economic exploitation defined the early nationalist strategy.

Explanation

The geographical arrangement of the mountain ranges in the northern part of the Indian subcontinent follows a consistent latitudinal progression from the Trans-Himalayas down to the Outer Himalayas. The Karakoram range is the northernmost system, situated primarily in the Gilgit-Baltistan and Ladakh regions. Progressing south, the Ladakh range lies between the Karakoram and the Zaskar ranges, situated north of the Indus River. The Zaskar range follows further south, acting as a climatic divide between the Indus Valley and the higher Himalayan regions. The Shivalik range, also known as the Outer Himalayas, is the southernmost range of the Himalayan mountain system, forming the transition between the mountains and the Indo-Gangetic plains. This spatial distribution places the ranges in the specific North-to-South order of Karakoram, Ladakh, Zaskar, and Shivalik.

Explanation

Monex, or the Monsoon Experiment, was a major international scientific venture conducted in 1979 as part of the Global Atmospheric Research Programme (GARP). It was organized under the auspices of the World Meteorological Organization (WMO) and the International Council of Scientific Unions (ICSU). While both India and the United States were significant contributors to the research, the experiment was a multi-national effort that also included heavy participation from the Soviet Union and various other countries. It was not a project established specifically or exclusively as a joint venture between the United States and India.

Explanation

The Rapti River originates in the Mahabharat Range of Nepal and flows through the plains of Uttar Pradesh before joining the Ghaghara River as a major left-bank tributary near Barhaj.

The Tista River rises in the Tso Lhamo Lake of the Eastern Himalayas and flows through Sikkim and West Bengal before entering Bangladesh, where it joins the Brahmaputra River (known there as the Jamuna) on its right bank.

The Hiranya (or Hiran) is a significant right-bank tributary of the Narmada River, originating in the Jabalpur district of Madhya Pradesh and joining the main stream near Sankal.

The Purna River is one of the principal tributaries of the Godavari River, draining the Vidarbha region of Maharashtra and the southern parts of Madhya Pradesh before its confluence with the Godavari.

Explanation

Tropical forests experience the highest rates of deforestation globally due to intensive land-use changes. These regions, particularly in South America, Southeast Asia, and Central Africa, are subject to significant pressure from large-scale commercial agriculture, such as cattle ranching, soybean cultivation, and palm oil plantations. Additionally, infrastructure expansion and the rising demand for timber and fuel lead to rapid forest clearance. Global assessments by organizations like the Food and Agriculture Organization (FAO) indicate that while some temperate regions show reforestation or stable cover, tropical biomes continue to lose millions of hectares annually, making them the primary zones of net forest loss on Earth.
