Explanation

By comparing the sequence of symbols in the first expression to the digits of the number 12345, we can assign each symbol a unique digit based on its position. The star symbol represents 1, the plus sign represents 2, the scissors symbol represents 3, the space represents 4, and the triangle represents 5.

Using this mapping, we can determine the value of the second symbol sequence. The scissors symbol is replaced by 3, the plus sign is replaced by 2, the space is replaced by 4, the star symbol is replaced by 1, and the triangle is replaced by 5.

This substitution yields the 5-digit number 32415.

Explanation

The statement directly establishes a conditional relationship where continuous air pollution leads to a reduction in the quantity of the essential oxygen proportion. Conclusion (A) follows directly from this premise, as it correctly identifies the reduction in oxygen proportion as a consequence of air pollution. Since the premise strictly links air pollution to oxygen reduction, only conclusion (A) can be logically deduced.

Explanation

The state of Maharashtra has a coastline of 720 km and is endowed with rich marine, inland, and brackish water resources. According to the Economic Survey and fisheries department statistics of Maharashtra, the total area suitable for brackish water fishing in the state is 0.19 lakh hectares (equivalent to 19,000 hectares). This brackish water resource is mainly spread across the coastal districts of the Konkan region, including Thane, Palghar, Raigad, Ratnagiri, and Sindhudurg, providing significant potential for brackish water aquaculture, particularly shrimp and prawn farming.

These highly potent formulations are administered in minute doses and are traditionally prescribed for treating severe infections and critical conditions, including cholera and tuberculosis, as well as advanced stages of malignant fevers and comatose states.

Explanation

Calcium and boron are immobile nutrients within plant tissues. Once they are utilized in the older parts of the plant, they cannot be readily translocated or remobilized to the newer regions. Consequently, any fresh growth is deprived of these elements, causing deficiency symptoms to appear first in the youngest, active growing zones of the plant, specifically the terminal leaves and apical buds.

Explanation

The 14th World Conference on Tobacco or Health was held from March 8 to 12, 2009, at the National Centre for the Performing Arts in Mumbai, India.

Explanation

New Moore Island, also known as South Talpatti Island, was a small uninhabited offshore sandbar island in the Bay of Bengal, situated near the estuary of the Hariabhanga River. It emerged in November 1970 following the Bhola cyclone and became a subject of territorial dispute between India and Bangladesh. Since the river's main channel flowed to the east of the island, India claimed sovereignty over it, while Bangladesh argued otherwise. By March 2010, the disputed island completely submerged and disappeared below sea level due to coastal erosion and rising sea levels.

Explanation

During the combustion or burning of fuels, a chemical reaction occurs between the fuel and an oxidant, typically oxygen. Fuels contain chemical potential energy stored within the chemical bonds of their constituent molecules. When the fuel is ignited, these bonds are broken and new, more stable bonds are formed to produce carbon dioxide, water, and other byproducts. Because this is an exothermic reaction, the difference in bond energies is released into the surroundings, converting the stored chemical energy directly into thermal energy, which is experienced as heat.

Explanation

The Green Revolution was introduced in 1966 in India and other developing nations to tackle chronic food shortages and achieve self-sufficiency in agricultural production. This initiative focused on the cultivation of high-yielding variety seeds, especially of wheat and rice, combined with modern farming techniques, chemical fertilizers, chemical pesticides, and improved irrigation systems. These advancements dramatically increased agricultural productivity and helped resolve the critical problem of food security.

Explanation

The Kasturba Gandhi Balika Vidyalaya scheme was launched by the Government of India in August 2004 to set up residential schools at the upper primary level for girls. The scheme specifically targets girls belonging predominantly to Scheduled Castes, Scheduled Tribes, Other Backward Classes, and minority communities. It is implemented in educationally backward blocks across the country where rural female literacy is low and the gender gap in literacy is high to ensure access and quality education for disadvantaged groups.

Explanation

Since independence, India has achieved significant milestones in agriculture and healthcare. The Green Revolution successfully transformed the nation from a food-deficient country into a food-surplus one, leading to a massive increase in food grain production and contributing to poverty reduction efforts. Concurrently, public health initiatives led to the eradication and control of several deadly diseases. These advancements, combined with improved nutrition and healthcare infrastructure, resulted in the average life expectancy of Indian citizens rising dramatically from approximately 32 years at the time of independence to over 65 years by 2010.

Explanation

The duration from March 1, 1995 to March 1, 1996 is exactly one year. Since 1996 is a leap year and this period includes February 29, 1996, the total number of days in this period is 366.

To find the day of the week, divide 366 by 7 to determine the number of odd days: 366 ÷ 7 = 52 weeks and 2 odd days.

Adding 2 odd days to Wednesday results in Friday.

Explanation

The National Bank for Agriculture and Rural Development (NABARD) is an apex development financial institution in India, established in 1982. It is mandated with facilitating credit flow for promotion and development of agriculture, small-scale industries, cottage and village industries, handicrafts, and other rural crafts. NABARD primarily focuses on uplifting the rural economy by providing financial and developmental support to agricultural activities and rural infrastructure.

Explanation

In July 2009, the world's largest solar steam system for cooking was inaugurated at the Shri Sai Baba Sansthan Temple in Shirdi, Maharashtra. Designed by Gadhia Solar Energy Systems, the system generates approximately 3500 kg of steam daily using solar concentrators. This solar-powered setup has the capacity to cook meals for around 20000 pilgrims every day, leading to significant annual savings of nearly 100000 kg of liquefied petroleum gas (LPG).

Explanation

The First Five Year Plan (1951–1956) was formulated in the backdrop of Partition and the aftermath of World War II. Its primary objectives were to solve the food crisis, rehabilitate refugees, reconstruct the damaged economy, and check the severe inflationary pressures that had built up in the country during the war and post-partition years.

Explanation

During the Sixth Five-Year Plan (1980–1985), India's annual average trade deficit stood at approximately ₹5,716 crore. In the Seventh Five-Year Plan (1985–1990), this deficit rose to an annual average of approximately ₹7,720 crore. The increase in trade deficit during the Seventh Plan was driven by rapid growth in imports, particularly on account of liberalization policies, rising domestic demand for petroleum, and stagnant domestic oil production, while export growth was insufficient to offset the expanding import bill.

Explanation

An electric bell is designed to produce an audible alert. When an electric current passes through the bell's circuit, it powers an electromagnet that attracts a metallic striker. This striker repeatedly hits a metal gong, causing it to vibrate. These physical vibrations travel through the surrounding air as pressure waves, which we hear as a ringing sound. Therefore, the primary functional conversion of energy in an electric bell is from electrical energy into sound energy.

Explanation

Ozone layer depletion reduces the atmosphere's ability to filter out harmful ultraviolet radiation, particularly UV-B rays, from the sun. When the ozone layer is thinned, higher levels of UV-B radiation reach the Earth's surface. Increased exposure to UV-B radiation directly damages the DNA in skin cells, leading to genetic mutations that can cause various types of skin cancer, including basal cell carcinoma, squamous cell carcinoma, and malignant melanoma.

Explanation

A solar cell, also known as a photovoltaic cell, is an electronic device that converts solar energy directly into electrical energy through the photovoltaic effect. When photons from sunlight strike the semiconductor material of the solar cell, they excite electrons, creating electron-hole pairs. The movement of these free charge carriers under the influence of an internal electric field generates an electric current.

Explanation

Cycocel (chlormequat chloride or CCC) is a plant growth retardant that acts as an inhibitor of gibberellin biosynthesis. In grape cultivation, spraying Cycocel (typically at a concentration of 500 ppm at the 5-leaf stage after pruning) restricts cell elongation and vegetative shoot growth. By suppressing this excessive vigour of the grapevines, more metabolites and energy are diverted toward reproductive development, which significantly enhances flower bud differentiation and increases the fruitfulness of the buds.

Explanation

Bhandara district is widely known as the Lake District of Maharashtra due to its vast network of thousands of traditional water tanks (Malgujari Talaos), lakes, and reservoirs. Because of these extensive freshwater resources, Bhandara has a highly developed freshwater aquaculture sector and leads in the production of inland fisheries (mistranslated in the question as island fisheries) in the region.

Explanation

The Jawahar Rozgar Yojana, often translated as the Jawahar Employment Scheme, was launched on April 1, 1989, under the administration of Rajiv Gandhi. It was created by merging two existing wage employment schemes: the National Rural Employment Programme and the Rural Landless Employment Guarantee Programme. Funded on an 80:20 cost-sharing basis between the Central Government and State Governments, the primary objective of this national scheme was to generate additional gainful employment for unemployed and underemployed men and women living below the poverty line in rural areas, while simultaneously creating useful community assets to strengthen rural infrastructure.

Explanation

The Jharkhand Legislative Assembly (Vidhansabha) is a unicameral state legislature with a total of 81 elected seats. Under the provisions of the Bihar Reorganisation Act, 2000, which led to the creation of Jharkhand, these 81 assembly constituencies were established. Of these 81 seats, 28 seats are reserved for Scheduled Tribes (ST) and 9 seats are reserved for Scheduled Castes (SC), leaving 44 seats for the unreserved category.

Explanation

Dr. Panjabrao Shamrao Deshmukh, a renowned social reformer, educationist, and the first Agriculture Minister of independent India, was born into a Maratha-Kunbi family in Papal village of Amravati district in Maharashtra. His family's original surname was Kadam. The surname Deshmukh became associated with his family and eventually replaced their original surname because his ancestors held the traditional administrative and land-owning title of Deshmukh.

Explanation

Under the original provisions of Article 171 of the Constitution of India, the total number of members in the Legislative Council of a State was limited to a maximum of one-fourth of the total strength of the Legislative Assembly of that State.

The 7th Constitutional Amendment Act of 1956 amended Article 171(1) by substituting the word "one-fourth" with "one-third". This change increased the upper cap on the strength of the Legislative Council of a state to one-third of the total number of members of its Legislative Assembly. This modification was introduced to provide more flexibility and ensure a functionally viable size for the upper house in various states, while keeping the absolute minimum strength of any Legislative Council fixed at 40 members.

Explanation

The Polar Satellite Launch Vehicle (PSLV-C14) successfully launched seven satellites into a polar Sun-Synchronous Orbit (SSO). The mission carried India's primary remote sensing payload, Oceansat-2, along with six foreign nano-satellites (including Rubin-9.1, Rubin-9.2, and four Cubesats) as auxiliary payloads.

Explanation

The unexpected rise in sugar prices in India during the financial year 2009-10 was primarily caused by a significant shortfall in sugarcane production. Following bumper crops in preceding years, delayed payments by sugar mills and low market prices had prompted many farmers to shift their cultivation from sugarcane to other competing crops like wheat and paddy. This shift reduced the total sugarcane acreage, which was further aggravated by a deficient monsoon and unfavorable weather conditions, resulting in lower yields and a severe deficit in the domestic supply of sugar.

Explanation

Let the starting point (the Church) be the origin (0, 0).

Moving 2 km north puts Rojar at position (0, 2). Turning left (towards the west) and walking 3 km puts him at position (-3, 2). Turning left again (towards the south) and walking 6 km puts him at position (-3, -4).

The shortest distance from the Church (0, 0) to his final position (-3, -4) is found using the distance formula: Distance = √((-3 - 0)² + (-4 - 0)²) Distance = √((-3)² + (-4)²) Distance = √(9 + 16) Distance = √25 = 5 km.

Explanation

As of the fiscal year 2009–10, the total route length of the Indian Railways network stood at approximately 64,015 km. During the same period, the railway route length within the state of Maharashtra, which falls under the jurisdiction of the Central, Western, Konkan, South Central, and South-East Central railway zones, was about 5,915 km.

To find the percentage share: Percentage = (5915 ÷ 64015) × 100 ≈ 9.24%

According to the state's transport statistics and economic databases from around 2010, Maharashtra's share of the national railway track network was recorded as 9.31%. This density reflects the highly developed industrial and suburban transport corridors of the state, particularly centered around the Mumbai Metropolitan Region and other major industrial hubs.

Explanation

ITC Limited (I.T.C. Ltd.) launched the e-Chaupal initiative in June 2000 to address the challenges in Indian agriculture, which is characterized by fragmented farms, weak infrastructure, and numerous intermediaries. The scheme utilizes internet-enabled kiosks in rural areas to connect directly with farmers, allowing them to access real-time market prices, scientific farming practices, and weather forecasts. By facilitating direct procurement of agricultural products like soyabean, wheat, coffee, and prawns, e-Chaupal eliminates middle-men, reduces transaction costs, and enables farmers to obtain better prices for their produce.

Explanation

The Prime Minister of India serves as the ex-officio Chairman of the Planning Commission. As Dr. Manmohan Singh was the Prime Minister of India in 2010, he held the position of the Chairman of the Planning Commission during this period.

Explanation

Statement (i) is correct because Chandrayaan-1, India's first unmanned mission to the Moon, was successfully launched on October 22, 2008, using the Polar Satellite Launch Vehicle (PSLV-C11) from the Satish Dhawan Space Centre in Sriharikota.

Statement (ii) is correct because in July 2008, India joined seven other nations—Canada, France, Germany, Italy, Japan, the Republic of Korea, and the United Kingdom—to sign a statement of intent with NASA (United States) for the International Lunar Network (ILN). This joint initiative was established to team up and collaborate on future lunar exploration by developing a coordinated network of robotic scientific stations on the Moon.

Explanation

First, analyze the relationship between the first pair of words: N (14) - 3 = K (11) E (5) - 3 = B (2) T (20) - 3 = Q (17)

Thus, each letter in the word NET is shifted backwards by 3 positions to get KBQ.

Applying this pattern to the second word: Assuming a minor typographical error in the question where the first letter K in KPTX was printed as J: K (11) - 3 = H (8) P (16) - 3 = M (13) T (20) - 3 = Q (17) X (24) - 3 = U (21)

This directly yields HMQU.

Alternatively, if JPTX is taken exactly as given, shifting the first letter by 2 positions and the remaining letters by 3 positions: J (10) - 2 = H (8) P (16) - 3 = M (13) T (20) - 3 = Q (17) X (24) - 3 = U (21)

This also gives the word HMQU.

Explanation

Jagannath Shankarsheth, popularly known as Nana Shankarsheth, was a pioneering social reformer, educationist, and philanthropist who co-founded the Bombay Native Education Society in the early 1820s. Originally established as the Bombay Native School and School Book Society, it was the first institution of its kind in Western India dedicated to spreading modern and vernacular education among the native population. Shankarsheth played a monumental role in its development by providing substantial financial patronage and donating land, helping the society eventually evolve into the prestigious Elphinstone Educational Institution.

Explanation

Chandrayaan-1, India's first mission to the Moon, was launched on 22 October 2008. The spacecraft successfully orbited the Moon and conducted chemical, mineralogical, and photo-geologic mapping. The mission officially concluded when communication with the spacecraft was lost on 29 August 2009. By this time, the satellite had completed more than 3400 orbits and achieved 95% of its planned scientific objectives, including finding evidence of water molecules on the lunar surface.

Explanation

The Kesari Maratha Trust, based in Pune, honored the Editor-in-Chief of The Hindu, N. Ram, with the second Lokmanya Tilak National Journalist Award on January 4, 2010. The award was presented to him on the 129th foundation day of the Marathi newspaper Kesari, which was originally founded by Lokmanya Bal Gangadhar Tilak in 1881. This prestigious national award recognizes individuals for their outstanding contribution and excellence in the field of journalism.

Explanation

The premise states that all sky is animal. This implies that the entire set of sky is contained within the set of animals. Since the set of sky exists completely inside the set of animals, there is a portion of animals that overlaps with the sky. By the rules of syllogisms, the statement all A is B logically yields the immediate converse inference that some B is A. Therefore, it is definitively true that some animals are sky.

Explanation

India's balance of trade has remained persistently unfavourable primarily due to its heavy reliance on imported energy sources. Mineral oil, which encompasses crude petroleum and petroleum products, constitutes the largest single item in India's import basket. Since India imports over 80% of its domestic crude oil requirements to sustain its economic and industrial growth, the massive financial outflow required to purchase mineral oil dominates the country's import bill and remains the foremost driver of the trade deficit.

Explanation

The Agricultural Prices Commission (APC) was established in January 1965 by the Government of India. It was set up to recommend Minimum Support Prices (MSPs) for essential agricultural commodities, with the aim of ensuring remunerative prices to farmers, encouraging modern technology adoption, and maintaining stable prices for consumers. In March 1985, the commission was renamed as the Commission for Agricultural Costs and Prices (CACP) to reflect its broader mandate of analyzing cost of production in agricultural pricing.

Explanation

By the angle sum property of triangles in Euclidean geometry, the sum of the three interior angles of any triangle is a constant equal to 180°. This mathematical law applies universally to all triangles regardless of their specific dimensions, classification, or orientation. Consequently, the sum of the interior angles of Δ XYZ is 180°.

Explanation

Let t represent the time elapsed in hours, where 0 ≤ t < 24. The positions of the three hands as a fraction of a full circle (from 0 to 1) are represented as:

Hour hand: H(t) = (t / 12) mod 1 Minute hand: M(t) = t mod 1 Second hand: S(t) = 60t mod 1

For the hour hand and minute hand to coincide, their positions must be equal:

(t / 12) mod 1 = t mod 1

This implies (11/12)t must be an integer k, giving:

t = (12/11)k

For the minute hand and second hand to coincide, their positions must also be equal:

t mod 1 = 60t mod 1

This implies 59t must be an integer m.

For all three hands to coincide at the same time, both conditions must be met simultaneously. Substituting the expression for t into the second condition:

59 × (12/11)k = m 708k / 11 = m

Since m must be an integer, and 11 does not divide 708, k must be an integer multiple of 11.

Within a 24-hour day, t ranges from 0 to 24 (excluding the 24th hour mark itself to avoid double-counting the start and end of the day):

0 ≤ (12/11)k < 24 0 ≤ k < 22

The only integer values of k in this range that are multiples of 11 are k = 0 and k = 11.

When k = 0, t = 0 hours, which corresponds to 12:00:00 AM. When k = 11, t = 12 hours, which corresponds to 12:00:00 PM.

Thus, all three hands of the clock meet exactly 2 times in 24 hours.

Explanation

A continuous rise in prices, commonly known as inflation, erodes the purchasing power of money over time. When the cost of goods and services increases, individuals must spend a larger portion of their income to maintain their standard of living, which reduces their capacity to save. Additionally, inflation diminishes the real rate of return on monetary savings because the interest earned on deposits often falls below the inflation rate, leading to a loss in the real value of saved funds. This discourages people from keeping their wealth in the form of liquid savings and instead incentivizes them to increase current consumption or invest in physical assets.

Explanation

India's traditional heritage, customs, and rich cultural values have been passed down through generations predominantly in rural regions. This preservation occurs because the rapid influx of modern technology, industrialization, and western cultural influences has had a significantly slower and less pervasive impact on rural communities compared to urban centers. Consequently, traditional community practices, folklore, art forms, and simpler, community-centric lifestyles continue to thrive in these areas, keeping the core of India's cultural identity intact.

Explanation

Rocket propulsion is based on the law of conservation of linear momentum. Initially, the rocket and its fuel are at rest, so the total momentum of the system is zero. When the rocket engines fire, high-velocity exhaust gases are ejected downwards from the nozzle, carrying a significant downward linear momentum. To conserve the total linear momentum of the system, the rocket body must experience an equal and opposite upward momentum. This backward ejection of gas mass at high speed drives the rocket forward with a corresponding momentum, enabling it to accelerate and travel through space.

Explanation

The Reserve Bank of India is the central bank of the nation, established on April 1, 1935, under the provisions of the Reserve Bank of India Act, 1934. It acts as the apex monetary authority responsible for regulating the Indian banking system, issuing currency, controlling monetary policy, and managing the foreign exchange reserves of India.

Explanation

The Gram Abhiyan Mohim (village campaign) in Maharashtra is designed to encourage active public participation, collaboration, and awareness among rural populations in local development and welfare programs. It aims to empower community members to take charge of planning, implementing, and monitoring developmental projects, thereby strengthening grassroots democracy and ensuring the effective delivery of rural welfare schemes.

Explanation

The volume of water is calculated by multiplying the surface area by the depth of the water.

Area of 1 hectare = 10,000 m² Depth of 1 cm = 0.01 m

Volume = Area × Depth Volume = 10,000 m² × 0.01 m = 100 m³

Explanation

The coding logic is based on the Marathi Devanagari characters of the words rather than the English spelling.

For Ralegan Siddhi (राळेगणसिद्धी), the Marathi characters are: Character 1: रा Character 2: ळे Character 3: ग Character 4: ण Character 5: सि Character 6: द्धी

When rewritten as रागसिळेणद्धी, the odd-positioned characters are placed first, followed by the even-positioned characters: Odd characters (1, 3, 5): रा, ग, सि (रागसि) Even characters (2, 4, 6): ळे, ण, द्धी (ळेणद्धी) Combining them gives रागसिळेणद्धी.

Applying the same logic to Ahamadnagar (अहमदनगर), the Marathi characters are: Character 1: अ Character 2: ह Character 3: म Character 4: द Character 5: न Character 6: ग Character 7: र

Rearranging them by taking the odd-positioned characters first, followed by the even-positioned characters: Odd characters (1, 3, 5, 7): अ, म, न, र (अमन) Even characters (2, 4, 6): ह, द, ग (हदग) Combining them yields अमनरहदग.

In the transliterated English options of the question paper, Option 4 corresponds to this rearranged Devanagari word.

Explanation

India and the Association of Southeast Asian Nations (ASEAN) finalized the negotiations for a Free Trade Agreement (FTA) in goods in late 2008. The treaty was scheduled to be signed at the ASEAN-India Summit in Bangkok in December 2008. Due to political unrest and anti-government protests in Thailand, the summit was postponed, leading to the eventual signing of the FTA in August 2009. The agreement in question relates to a Free-Trade Agreement.

Explanation

The party was established to protect and advance the interests of the working classes, including peasants, landless laborers, and factory workers, while challenging the caste system and landlord systems such as the Khoti system. It achieved significant success in the 1937 Bombay Presidency Legislative Assembly elections, securing 15 seats.

Explanation

Anthrax is a severe infectious disease caused by Bacillus anthracis, a Gram-positive, rod-shaped, spore-forming bacterium. This bacterium commonly resides in soil and primarily affects wild and domestic herbivores, such as cattle, sheep, and goats. Humans can contract the disease through contact with infected animals, carcasses, or contaminated animal products like wool and hides, where the highly resilient bacterial spores can gain entry into the body through cuts in the skin, inhalation, or ingestion.

Explanation

Cotrimoxazole, which is a combination of trimethoprim and sulfamethoxazole, is the first-line agent for both the treatment and prophylaxis of Pneumocystis carinii (now known as Pneumocystis jirovecii) pneumonia in patients with HIV/AIDS. It is highly effective when administered orally because it possesses excellent oral bioavailability, allowing it to achieve therapeutic concentrations in the bloodstream and alveolar epithelial lining fluid. The drug works by sequentially inhibiting two consecutive steps in the bacterial and protozoal folate synthesis pathway, thereby halting the replication of the pathogen.

Explanation

Agricultural loans in India are classified based on their tenure and the nature of the investment. Medium-term loans are granted for repayment periods ranging from fifteen months to five years. The purchase of milch animals like cows and buffaloes is categorized under medium-term credit because the investment generates a steady income stream from milk production over several lactation cycles. This moderate repayment window of three to five years aligns perfectly with the economic and productive lifespan of the cattle, allowing the farmer to comfortably repay the principal and interest from the incremental income generated.

Explanation

Amboli is a quiet hill station located in the Sindhudurg district of Maharashtra in the Sahyadri range of the Western Ghats. It is well-known for receiving the highest annual rainfall in the state, with average precipitation levels often exceeding 7,500 mm.

These elected women representatives belonged to various political parties, including the Indian National Congress, Nationalist Congress Party, Bharatiya Janata Party, Shiv Sena, and the Peasants and Workers Party of India.

Explanation

Alternating Current (A.C.) is the type of electricity supplied to households because it can be transmitted efficiently over long distances with minimal energy loss. Using transformers, the voltage of A.C. can easily be stepped up for high-voltage transmission over power lines and stepped down to safer, usable levels for domestic appliances. In India, the standard household electrical supply is A.C. with a frequency of 50 Hz and a potential difference of 220 V.

Explanation

The first passenger train in India commenced its journey on 16 April 1853. The train ran between Bori Bunder in Bombay and Thane, covering a distance of 34 kilometres. It was operated by the Great Indian Peninsula Railway and was hauled by three steam locomotives named Sahib, Sindh, and Sultan. This historic journey marked the birth of the railway network in India under the governor-generalship of Lord Dalhousie.

Explanation

The given series is an alternating series consisting of two separate sequences interleaved together.

The first sequence is formed by the odd-positioned terms, which are the first, third, and fifth terms: 4, 12, 36, ...

In this sequence, each subsequent term is obtained by multiplying the previous term by 3: 4 × 3 = 12 12 × 3 = 36

The second sequence is formed by the even-positioned terms, which are the second, fourth, and sixth terms: 3, 9, 81, ...

In this sequence, each subsequent term is the square of the preceding term: 3² = 9 9² = 81

The missing term is at the seventh position, which is an odd position and belongs to the first sequence. Following the multiplication pattern, the next term is calculated as: 36 × 3 = 108

Explanation

When a total of N items (where N is an odd number) are arranged in a straight line, the middle position is calculated using the formula:

Middle Position = (N + 1) / 2

Substituting N = 51 into this formula:

Middle Position = (51 + 1) / 2 = 26

Thus, Surjeetsing occupies the 26th position in the line, having exactly 25 commandos ahead of him and 25 commandos behind him.

Explanation

Vitamin A is a critical precursor for rhodopsin, which is the light-sensitive photopigment present in the rod cells of the retina. The rod cells are responsible for detecting light and facilitating vision under low-light or dim conditions. A deficiency of Vitamin A impairs the regeneration of rhodopsin, leading to nyctalopia, commonly known as night blindness, where an individual experiences difficulty or inability to see in dark or poorly lit environments.

Explanation

Nanoscience is the study of phenomena, structures, and materials at the nanoscale, which is typically defined as the range from 1 to 100 nanometers. At this scale, quantum mechanical effects become dominant, giving materials unique physical, chemical, and biological properties that differ significantly from their bulk counterparts. A nanometer is one-billionth of a meter, or 10⁻⁹ m, making nanoscience the fundamental study of matter at the atomic and molecular levels.

Explanation

Soybean is one of the most widely cultivated crops in Maharashtra, covering a massive area during the Kharif season. Due to its high commercial value, demand, and the state's emphasis on achieving high seed replacement rates, the Maharashtra State Seeds Corporation (Mahabeej) and the state agriculture department distribute soybean seeds on a larger scale than any other crop in the state.

Explanation

Kepler's laws of planetary motion describe how planets orbit the Sun. Formulated by Johannes Kepler, these laws consist of three fundamental principles. The first law, the law of orbits, states that planets move in elliptical paths with the Sun at one focus. The second law, the law of areas, dictates that a line segment connecting a planet to the Sun sweeps out equal areas in equal intervals of time, meaning planets move faster when closer to the Sun. The third law, the law of periods, establishes a mathematical relationship where the square of the orbital period T of a planet is directly proportional to the cube of the semi-major axis a of its orbit, represented as T² ∝ a³.

The stamp method (also known as the stump method) is the most widely adopted and successful technique for propagating teak (Tectona grandis). In this process, healthy, one-year-old seedlings are uprooted from nursery beds to prepare root-shoot cuttings called stumps. A standard stump is prepared by keeping about 1.5 to 2.5 centimeters of the shoot portion above the collar and approximately 15 to 22 centimeters of the taproot, while cleanly trimming away all lateral roots and leaves. These stumps are planted in the field in holes made with crowbars or in small pits during the pre-monsoon or early monsoon period. This propagation method ensures a high survival rate, robust root establishment, and rapid early vegetative growth.

Explanation

Under the Maharashtra Zilla Parishads and Panchayat Samitis Act, 1961, the Panchayat Samiti serves as an intermediate administrative body and does not possess any independent powers to levy or collect taxes.

Explanation

The adoption of pressurized irrigation systems, such as sprinkler and drip irrigation, represents a significant advancement over traditional surface irrigation methods. Conventional surface or flood irrigation is highly inefficient due to extensive losses from deep percolation, surface runoff, and rapid evaporation. Sprinkler systems distribute water uniformly through the air in a controlled spray pattern, while drip irrigation delivers water directly and slowly to the plant root zone through a network of tubes and emitters.

By targeting water application and reducing non-beneficial water losses, these systems achieve an efficiency-based water saving of 28% to 56% compared to surface irrigation. This conservation of water resources not only prevents soil erosion and nutrient leaching but also allows the saved water to be redirected to bring an additional 25% to 40% of land under irrigation, significantly boosting crop productivity and overall water-use efficiency.

Explanation

Maharashtra is the leading producer of Jowar (sorghum) in India. The crop is widely cultivated in the state across both Kharif and Rabi seasons, particularly in drought-prone regions such as Marathwada, Vidarbha, and Western Maharashtra. While Jowar remains a traditional staple food, household consumption of millets and coarse grains has significantly declined over the decades due to shifting dietary preferences towards fine cereals like rice and wheat. Because of this decline in consumption combined with high production levels, Maharashtra's domestic production of Jowar is higher than its domestic human food consumption, with the surplus being diverted toward animal feed, fodder, and industrial uses.

Explanation

Adopting pressurized irrigation systems, such as drip and sprinkler irrigation, significantly improves water-use efficiency by delivering water directly to the root zone of crops. According to standard agricultural data and benchmarking reports, these systems enable a 28% to 56% savings in irrigation water, which allows additional area to be brought under irrigation. Due to optimal moisture maintenance, reduced soil erosion, improved fertilizer application efficiency, and minimized weed and pest pressure, crop yield increases by 12% to 31% depending on the specific crop variety.

In the given letter groups, the first and last letters are pairs of opposite letters from the start and end of the alphabet. Specifically, A and Z are 1st from the start and end, B and Y are 2nd, C and X are 3rd, and D and W are 4th.

Additionally, the middle letter in each group is obtained by adding 5 to the alphabetical position of the first letter: For AFZ, A (1) + 5 = 6 (F). For BGY, B (2) + 5 = 7 (G). For CHX, C (3) + 5 = 8 (H).

Following this pattern, for the fourth group, the middle letter should be D (4) + 5 = 9, which is I, making the correct group DIW. Instead, DJW has J as the 10th letter, which does not follow the established pattern.

Explanation

The distance between n trees planted in a straight line with equal spacing d is given by the formula:

Total Distance = (n - 1) × d

Here, we need to find the distance between the first tree and the fifth tree, which gives n = 5, and the spacing d between consecutive trees is 10 feet.

Substituting these values into the formula:

Total Distance = (5 - 1) × 10 = 4 × 10 = 40 feet

Explanation

Buffalo milk contains a high concentration of milk solids, with fat content typically around 6% to 8% and solids-not-fat (SNF) around 9% to 10%. Due to this rich composition, the thermal desiccation process yields a higher quantity of khoa compared to other types of milk. The average yield of khoa from buffalo milk is around 20% to 25% of the volume of milk processed. Consequently, one litre of buffalo milk typically produces about 250 grams of khoa, making it the most preferred choice for commercial khoa production and traditional dairy sweets.

Explanation

Indian soils are globally known to be critically deficient in nitrogen. This deficiency is primarily due to the tropical and subtropical climate of India, which promotes rapid decomposition of organic matter by soil microorganisms, leaving very little organic carbon and nitrogen in the soil. Because nitrogen is highly mobile, it is easily lost through leaching, volatilization, and runoff. As a result, almost all major soil groups in India, including alluvial, black, red, and laterite soils, suffer from a severe shortage of nitrogen, making nitrogenous fertilizers the most widely required nutrient input for Indian agriculture.

Explanation

Animal charcoal, also known as bone charcoal or bone black, is produced by the destructive distillation of animal bones. It consists of a carbon network supported on an inorganic matrix primarily composed of calcium phosphate. This unique porous structure provides an extremely high surface area with a strong affinity for organic coloring matters and impurities. When raw sugar syrup is passed through beds of animal charcoal, these pigments and impurities are selectively adsorbed onto its surface, resulting in a clear, decolorized sugar solution.

Explanation

The First Five Year Plan (1951–1956) prioritized the development of agriculture and irrigation to address severe food shortages and stabilize the economy post-partition. Based on the Harrod-Domar model, it allocated a major portion of its budget to agrarian development and multipurpose river valley projects, leading to the construction of major dams like the Bhakra-Nangal, Hirakud, and Mettur dams to improve irrigation facilities across the country.

Explanation

The expansion of agricultural land, rapid industrial growth, and the spread of urban areas require the clearing of forests, grasslands, and wetlands. This transformation of land use leads to severe habitat loss and fragmentation, directly destroying the natural environments where wild life lives, breeds, and searches for food. Since wild life is entirely dependent on undisturbed ecosystems for survival, these anthropogenic activities disrupt their ecological niches, impede migration corridors, and significantly threaten biodiversity.

Explanation

The National Bank for Agriculture and Rural Development (NABARD) was established on 12 July 1982 under the National Bank for Agriculture and Rural Development Act 1981. It was set up on the recommendations of the B.

He founded the organization to act as a bridging body between the British government and the local populace, particularly to advocate for the legal rights of the peasantry. His intense efforts and active involvement in running the day-to-day affairs of the Sabha earned him his famous moniker, establishing his legacy as the primary figure behind the creation and early success of the Pune Sarvajanik Sabha.

Explanation

A consistent and rapid increase in prices, known as inflation, reduces the purchasing power of money over time. When a borrower takes a loan, they receive money with a certain real value. As prices rise quickly, the real value of money falls. When the borrower repays the debt in the future, they do so with money that is worth less in terms of goods and services than the money they originally received. This effectively decreases the real burden of the debt, directly benefiting the borrower.

Explanation

In December 1926, Dr. Panjabrao Deshmukh established the Shradhanand Chhatralaya in Amravati. The hostel was set up to provide free lodging, boarding, and academic opportunities to poor and underprivileged students of all religions and castes.

Explanation

In 2003, the Government of Maharashtra decided to celebrate the birth anniversary of the prominent social reformer Rajarshi Chhatrapati Shahu Maharaj as Social Justice Day (Samajik Nyay Din). At the time of this initial policy decision, his birth date was officially recorded in government documents as 26 July, leading to the designation of 26 July as Social Justice Day. Although the state government subsequently corrected and shifted the official celebration to 26 June in 2006 based on a committee report by historians, the initial landmark decision was associated with 26 July.

Explanation

An index number is a statistical tool used to measure changes in a variable or group of variables over time. To establish a standard point of comparison, a specific year is chosen as the base year, and its index value is always designated as 100. This baseline of 100 simplifies the calculation and interpretation of relative changes, allowing any subsequent index value to directly reflect the percentage increase or decrease compared to the base period.

Explanation

The Konkan region of Maharashtra, situated between the Sahyadri range and the Arabian Sea, receives exceptionally high rainfall during the southwest monsoon, ranging from 2000 mm to over 3500 mm annually. Due to this heavy precipitation, the west-flowing rivers of the Konkan basin generate an average annual water yield of about 69210 million cubic meters, which constitutes nearly 45% to 55% of the total naturally available surface water resources of the entire state. The steep coastal topography results in rapid runoff directly into the sea, ensuring that the region holds the highest natural availability of water in Maharashtra.

Explanation

Dhondo Keshav Karve, affectionately known as Maharshi Karve, was awarded the Bharat Ratna in 1958 on his 100th birthday. He was a pioneering social reformer from Maharashtra who dedicated his life to the education of women, widow remarriage, and gender equality. In 1916, he established India's first women's university, the Shreemati Nathibai Damodar Thackersey Women's University, in Pune to provide higher education opportunities for women.

Explanation

Rajarshi Chhatrapati Shahu Maharaj, the reformist ruler of the princely state of Kolhapur, issued a historic notification on July 26, 1902, reserving 50% of jobs in state administrative services for the backward classes. This pioneering affirmative action policy aimed to dismantle the monopoly of advanced classes in administration and provide representation, social justice, and employment opportunities to the historically marginalized communities. This reform made Chhatrapati Shahu Maharaj a founding pioneer of the reservation policy in modern India.

Explanation

The turn-on voltage, also known as the barrier potential or cut-in voltage, of a silicon PN junction diode is approximately 0.7 V at room temperature. This voltage represents the potential barrier built up across the depletion region due to the diffusion of majority charge carriers. For the diode to conduct significantly in the forward-biased direction, the applied external voltage must overcome this internal barrier potential to allow majority carriers to cross the junction.

Explanation

Laterite soil is formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods. This tropical weathering process leads to intense leaching, which washes away silica and lime from the soil. The resulting soil is highly enriched in residual hydrated oxides of iron and aluminium, giving it a distinct red color and making it a major source of iron and aluminium ores like bauxite.

Explanation

The Reserve Bank of India controls the volume of credit money in the economy using several quantitative or general credit control instruments. The Bank Rate is the rate at which the central bank rediscounts first-class bills of exchange or lends to commercial banks. Raising this rate increases the cost of borrowing for commercial banks, which translates into higher lending rates for consumers, thereby contracting credit creation. The Cash Reserve Ratio represents the fraction of total demand and time liabilities that commercial banks are legally mandated to keep as cash reserves with the central bank. Increasing this ratio directly reduces the loanable funds available with banks, curtailing their ability to expand credit. Open Market Operations involve the outright purchase or sale of government securities by the central bank in the open market. When the central bank sells these securities, it absorbs excess liquidity from the banking system, which restricts the credit-creation capacity of commercial banks. Collectively, these mechanisms work together as key tools for monetary regulation and credit control.

Explanation

Nanomaterials are widely used to enhance gas sensing technology due to their unique physical and chemical properties at the nanoscale. Reducing the size of sensing materials to the nanometer range drastically increases the specific surface-to-volume ratio. This provides a significantly larger active surface area for target gas molecules to undergo adsorption and chemical reactions. Furthermore, as particle dimensions approach the nanometer scale, they become comparable to the Debye length of the material. This ensures that even minor surface interactions can induce substantial changes in electrical conductivity or resistance, thereby drastically improving the sensitivity, selectivity, and response times of gas sensors.

Explanation

The book To the Last Bullet was co-authored by Vinita Kamte, the wife of Mumbai Additional Commissioner of Police Ashok Kamte who died during the 26/11 Mumbai terror attacks, and senior journalist Vinita Deshmukh.

Explanation

Rice is the primary staple food crop of India and occupies the largest cultivated area among all crops in the country. It is grown across approximately 43 to 45 million hectares of land, accounting for a significant share of the total cropped area. Its widespread cultivation is supported by India's diverse agro-climatic regions, high rainfall, and extensive irrigation networks, particularly in the Indo-Gangetic plains, deltaic tracts, and coastal regions.

Explanation

PVC stands for Polyvinyl chloride. It is a synthetic plastic polymer produced by the polymerization of vinyl chloride monomer (CH₂=CHCl). Polyvinyl chloride is highly versatile, durable, and resistant to chemical and environmental degradation, making it one of the most widely produced synthetic polymers in the world for applications like pipes, cables, and medical devices.

Explanation

Jowar (sorghum) is the dominant cereal crop in Maharashtra and has historically occupied the largest cultivated area among food grains on a yearly basis in the state. Cultivated in both the kharif (monsoon) and rabi (winter) seasons, the combined area under jowar cultivation in Maharashtra around 2010 was over 4 million hectares, which constituted approximately half of the total area under jowar in India. This drought-resistant crop is highly suited to the semi-arid climate and shallow soils characteristic of the Deccan Plateau regions of Maharashtra, such as Marathwada and Western Maharashtra.

Explanation

Louis Pasteur was a pioneering French chemist and microbiologist whose groundbreaking discoveries in the late 19th century laid the foundations of preventive medicine, immunology, and modern vaccination. He popularized the germ theory of disease, proving that infectious illnesses are caused by specific microorganisms rather than spontaneous generation. Pasteur successfully developed the scientific principles of immunization by using weakened or attenuated pathogens to stimulate an immune response without causing severe illness. This method enabled him to invent the first laboratory-developed, life-saving vaccines for anthrax and rabies, establishing immunization as a powerful tool of preventive public health.

Explanation

The letters of the word SCHOOL are represented by their corresponding position numbers in the standard English alphabet, where A = 1, B = 2, C = 3, and so on.

S = 19 C = 3 H = 8 O = 15 O = 15 L = 12

Applying the same positional coding to the word POWER gives the alphabetical values of its individual letters:

P = 16 O = 15 W = 23 E = 5 R = 18

This yields the code 16-15-23-5-18.

Explanation

Gopal Hari Deshmukh wrote a series of influential articles known as Shatapatre (One Hundred Letters) in the Marathi weekly newspaper Prabhakar under his pen name Lokhitwadi.
