Through these provisions, the Constitution envisions the creation of a non-authoritarian, democratic state that actively works toward the socio-economic development and well-being of all its citizens.

Explanation

Raja Rammohan Roy is widely regarded as the Father of the Indian Renaissance and the pioneer of modern India. He initiated a wave of socio-religious reforms in the early nineteenth century by promoting rationalism, monotheism, and human dignity. He played a crucial role in the abolition of the practice of Sati, leading to its legal ban in 1829. In 1828, he founded the Brahmo Sabha, which later grew into the Brahmo Samaj, to reform Hindu society from within. He was also a strong proponent of modern western education and free press, laying the intellectual foundation for India's modernization.

Explanation

The economic planning in India during the first seven Five-Year Plans (spanning from 1951 to 1990) prioritised the core objective of achieving self-reliance. After centuries of colonial rule, the primary focus of the national planners was to reduce the country's dependence on foreign nations for essential commodities, particularly food grains and industrial machinery. This strategy sought to prevent external interference in domestic policies and safeguard India's hard-won political sovereignty. To support this objective, the government adopted an inward-looking trade strategy focused on import substitution, protecting domestic industries from international competition through tariffs and quotas, while promoting the growth of indigenous capabilities in agriculture and heavy industries.

Explanation

From the given information, the relative scores of the players can be determined. Sourav scored more than Kambli, and Sachin also scored more than Kambli. This gives: Sourav > Kambli Sachin > Kambli

Sachin scored 36, which is not more than Sourav's score. This means Sourav's score is greater than or equal to Sachin's score: Sourav ≥ Sachin > Kambli

Since Kambli scored less than both Sourav and Sachin, neither Sourav nor Sachin can be the lowest scorer.

The problem also states that Kambli is not the lowest scorer. This means there must be at least one person who scored less than Kambli. This leaves only Rahul or Rabin to be the lowest scorer. Since Rahul is not present in the options, Rabin must be the lowest scorer.

Explanation

His historic tenure at Trinity College coincided with him receiving the Nobel Memorial Prize in Economic Sciences in 1998 for his contributions to welfare economics and social choice theory.

Explanation

The relative humidity of air is defined by the formula RH = (p_w)/(p^_w) × 100, where p_w is the partial pressure of water vapor and p^_w is the equilibrium vapor pressure of water at the given temperature. The saturation vapor pressure of water is directly proportional to temperature, meaning it increases significantly as the temperature rises from 30°C to 40°C. Because the actual amount of water vapor inside the room remains constant, the partial pressure p_w does not change, while the saturation vapor pressure p^_w increases. As a result, the ratio (p_w)/(p^_w) decreases, which causes the relative humidity to decrease.

Explanation

The Duckbill platypus is a primitive, egg-laying mammal (monotreme) that serves as an evolutionary connecting link between reptiles and mammals. It exhibits distinct reptilian characteristics, such as laying hard-shelled eggs, possessing a cloaca, and having a flexible reptilian-like skeleton with an interclavicle bone. Simultaneously, it possesses mammalian features, including hair on its body, mammary glands that secrete milk to nourish its young, and a diaphragm, representing the evolutionary transition from reptiles to mammals.

Explanation

The Battle of Buxar, fought on 22 October 1764, was the most defining and significant battle in establishing British supremacy in India. In this conflict, the English East India Company forces led by Major Hector Munro defeated the combined joint army of Mir Qasim (the Nawab of Bengal), Shuja-ud-Daulah (the Nawab of Awadh), and the Mughal Emperor Shah Alam II. Unlike earlier engagements which were won largely through intrigues and treachery, the Battle of Buxar was a classic display of superior British military strength and organization against the combined might of three major Indian powers. The victory culminated in the Treaty of Allahabad in 1765, through which the Mughal Emperor granted the Diwani rights—the right to collect revenue—of Bengal, Bihar, and Orissa to the Company. This acquisition of financial and administrative control over India's wealthiest province transformed a commercial trading entity into a sovereign ruling power, establishing undisputed British hegemony over northern India.

Explanation

The premise states that intelligence is one of the contributory factors of success. This means that intelligence is neither a sufficient condition nor a necessary condition for success.

Because intelligence is not a sufficient condition, possessing intelligence does not guarantee success. Therefore, statement a, which asserts that all intelligent persons are successful, is false.

Because intelligence is not a necessary condition, success can be attained through other contributing factors, meaning a successful person does not have to be intelligent. Therefore, statement c, which asserts that all successful persons are intelligent, is also false.

Explanation

The Constituent Assembly of India adopted the Constitution of India on November 26, 1949. This historic event is recorded in the Preamble of the Constitution, which states that the people of India, in their Constituent Assembly, adopted, enacted, and gave to themselves this Constitution on the twenty-sixth day of November, 1949. Some provisions of the Constitution, such as those relating to citizenship, elections, and provisional parliament, came into force immediately on this date, while the remaining bulk of the Constitution came into effect on January 26, 1950.

Explanation

The Government of India adopted the Structural Adjustment Programme in July 1991 in response to a severe balance of payments crisis. Under this programme, which was backed by financial assistance from the International Monetary Fund and the World Bank, India initiated comprehensive economic reforms consisting of stabilization measures and structural reforms. These reforms included deregulation of industries, trade liberalization, fiscal correction, and financial sector reforms, which marked the transition of the Indian economy towards a market-oriented system.

Explanation

Fiscal deficit is the excess of total budget expenditure over total budget receipts, excluding borrowings, during a financial year. Mathematically, it is expressed as:

Fiscal Deficit = Total Expenditure - (Revenue Receipts + Non-debt Capital Receipts)

Because this gap is financed entirely through borrowing, the fiscal deficit represents the total borrowing requirements of the government from all internal and external sources. It directly measures the net addition to the public debt, signifying the amount of increase in the government's overall debt liabilities during the year.

Explanation

Anushilan Samity was founded in Calcutta on March 24, 1902, by Pramathanath Mitra (Pramatha Mitra), who also served as its first president. The organisation was established as a secret revolutionary society in Bengal to propagate revolutionary ideas and spearhead the armed struggle against British colonial rule.

Explanation

Colloidal particles carry a similar electrical charge on their surfaces, which can be either positive or negative. This like charge results in mutual electrostatic repulsion between the particles, preventing them from aggregating or coalescing into larger, heavier particles. As a result of this constant repulsion and their continuous Brownian motion, the colloidal particles remain suspended in the dispersion medium and do not settle down under the influence of gravity.

Explanation

India signed a major defense agreement with Israel to acquire the Barak-1 missile system to equip its naval warships. Developed jointly by Israel Aerospace Industries and Rafael Advanced Defense Systems, the Barak is a point-defense missile system designed to protect maritime platforms against incoming anti-ship missiles, aircraft, and unmanned aerial vehicles.

Explanation

During the Delhi Sultanate, particularly organized under Sultan Shams-ud-din Iltutmish, the Iqta system was established as a crucial administrative and agrarian tool. An Iqta was a territorial assignment of land revenue granted to civil and military officers, known as Iqtadars or Muqtis, in lieu of direct cash salaries. The Iqtadars collected revenue from these designated regions to meet their personal expenses and maintain a specified number of troops for the Sultan's service, while also performing administrative and law-enforcement duties in their territories.

Explanation

Bhagat Singh, Rajguru, and Sukhdev were tried and convicted in the Lahore Conspiracy Case for the assassination of British police officer John Saunders in Lahore on December 17, 1928. The assassination was carried out by the Hindustan Socialist Republican Association (HSRA) to avenge the death of Lala Lajpat Rai, who had succumbed to injuries sustained during a brutal police lathi-charge during a protest against the Simon Commission. Following a high-profile trial by a special tribunal, the three revolutionaries were sentenced to death and subsequently hanged on March 23, 1931, in the Lahore Central Jail.

Explanation

The followers of Parsvanatha (the 23rd Tirthankara) and Vardhamana Mahavira were originally referred to as Nirgranthas or Nigranthas, which translates to those who are free from all bonds, fetters, or worldly attachments. After Mahavira attained Kaivalya (supreme knowledge) and came to be recognized as Jina (the conqueror of senses and desires), his followers and the religious tradition itself began to be called Jainas (followers of the Jina). This marked the transition of the sect's name from Nigranthas to Jainas.

Explanation

In August 2001, Lashkar-e-Jabbar, a militant group active in Jammu and Kashmir, issued a dress code decree demanding that all Kashmiri Muslim women wear the burqa in public by a deadline of September 1, 2001.

The outfit also dictated specific identification markers for non-Muslim women, such as saffron dupattas for Sikh women and bindis for Hindu women, to distinguish them in public.

Explanation

The massive release of electrical energy during a lightning discharge creates high electric field gradients and temperatures that ionize surrounding atmospheric gas molecules. Due to the polar nature of water molecules, these newly formed gaseous ions strongly attract water vapor. The ions act as highly effective cloud condensation nuclei, accelerating the aggregation and condensation of water droplets around them to induce the formation of rain.

Explanation

Anshan, located in the Liaoning province of Northeast China, is known as the Steel Capital of China. It is home to the Anshan Iron and Steel Group Corporation (Ansteel), which was developed as the country's first and largest integrated iron and steel administrative and production hub.

Explanation

Prudential norms refer to the guidelines and practices prescribed by central banking authorities, such as the Reserve Bank of India, to ensure the financial soundness, solvency, and overall stability of the banking system. These norms dictate how banks must manage their financial health through rules on capital adequacy, income recognition, asset classification, and provisioning for non-performing assets. In India, these standards were systematically implemented as part of the financial and banking sector reforms initiated after the Narasimham Committee recommendations of 1991 to align the domestic banking sector with international standards.

Explanation

Crates of Mallus, written as Cnues in the question, was a Greek philosopher and grammarian of the 2nd century BCE who is credited with constructing the earliest known terrestrial globe around 150 BCE.

Explanation

Nawab Salimullah of Dacca was a strong supporter of the Partition of Bengal in 1905 and opposed the Boycott and Swadeshi Movement. Viceroy Lord Curzon won his backing by offering him a low-interest government loan and promising to make Dacca the capital of the newly created Muslim-majority province of Eastern Bengal and Assam, which Salimullah believed would benefit the Muslim community of East Bengal. Seeking to safeguard Muslim interests separately from the mainstream nationalist movement, he actively campaigned against the anti-partition boycott and subsequently hosted the meeting in December 1906 that led to the foundation of the All-India Muslim League.

Explanation

The Non-Cooperation Movement was suspended by Mahatma Gandhi in February 1922 following the Chauri Chaura incident in Gorakhpur district of Uttar Pradesh. During this incident, a large crowd of protesters clashed with local police and set fire to a police station, leading to the deaths of twenty-two policemen. Guided by his strict commitment to absolute non-violence, Gandhi felt that the masses were not yet fully trained for a peaceful struggle and formally called off the agitation on 12 February 1922 through the Bardoli resolution.

Explanation

Let the number of wolves, foxes, and deer be represented by W, F, and D respectively.

According to the given information, the number of wolves is twice the number of foxes: W = 2F

The number of foxes is one-fourth the number of deer: F = ¼ D D = 4F

The ratio of the number of wolves to deer is: (W)/(D) = (2F)/(4F) = ½

Explanation

Drought is a prolonged period of abnormally low rainfall leading to water shortages, which directly results in a famine.

Rivers are water bodies whose overflow during heavy precipitation leads to a flood.

Mountains are elevated landforms with steep slopes where large rock fragments, known as boulders, are typically located.

Clouds consist of condensed water vapor suspended in the atmosphere and are seen in the sky.

Explanation

Surya Sen was a prominent Indian revolutionary who played a pivotal role in the struggle for independence against British rule, most notably by leading the historic Chittagong armoury raid in 1930.

Explanation

Article 79 of the Constitution of India explicitly states that there shall be a Parliament for the Union, which shall consist of the President and two Houses, namely the Council of States (Rajya Sabha) and the House of the People (Lok Sabha). Although the President of India is not a member of either House and does not sit in Parliament, they are an integral part of the legislative process. A bill passed by both Houses cannot become law without receiving the President's assent. Additionally, the President performs crucial parliamentary functions, such as summoning and proroguing the sessions of Parliament, dissolving the Lok Sabha, and addressing both Houses.

Explanation

Following the economic reforms initiated in 1991, the Indian economy transitioned towards service-led growth. During the decade of the nineties (from 1990-91 to 2000-01), the tertiary sector, which comprises services such as information technology, telecommunications, finance, trade, and transportation, grew at an average annual rate of approximately 7.82 percent. This rapid expansion in services outperformed the growth rates of both the industrial and agricultural sectors, establishing the tertiary sector as the primary driver of India's overall gross domestic product growth during the post-liberalization era.

Explanation

Ashoka's Major Rock Edict XIII (13th Rock Edict) provides a detailed account of the Kalinga War, which took place in the eighth year of his coronation (circa 261 BCE). This edict is the largest of all Major Rock Edicts and expresses Ashoka's deep grief, remorse, and repentance over the immense death, destruction, and suffering caused by the war. It marks his transformation from a conqueror through military force (Bheri-ghosha) to a conqueror through righteousness (Dhamma-vijaya).

Along with Lala Lajpat Rai and Bal Gangadhar Tilak, he formed the famous Lal-Bal-Pal triumvirate that advocated for radical methods such as Swadeshi, boycott of foreign goods, and national education to achieve Swaraj (self-rule), rather than the constitutional agitation and petitioning methods favored by the Moderates.

Explanation

When a plant cell is placed in a hypertonic solution, the external medium has a higher solute concentration and lower water potential than the cell sap. This concentration gradient drives the outward movement of water from the cell vacuole across the semipermeable cell membrane through the process of osmosis. As water leaves the cell, the volume of the protoplast decreases, causing it to shrink and pull away from the rigid cell wall in a process known as plasmolysis.

Explanation

An ordinary beam balance measures mass by comparing the gravitational force acting on an unknown mass with the gravitational force acting on a known standard mass. Because the acceleration due to gravity cancels out from both sides of the balance equation, the measurement yields the true mass of the object and remains constant regardless of changes in local gravity.

Explanation

Nitrogen fixation is the process by which inert atmospheric nitrogen (N₂) is converted into reactive and usable nitrogenous compounds, such as ammonia (NH₃), nitrates (NO₃^-), and nitrites (NO₂^-). Because atmospheric nitrogen has a strong triple covalent bond, most living organisms cannot utilize it directly from the air. Nitrogen-fixing microorganisms, both free-living and symbiotic, as well as industrial processes like the Haber-Bosch process, break this bond to combine nitrogen with hydrogen or oxygen, producing essential compounds that plants can readily assimilate to build proteins and other vital biomolecules.

Explanation

The Kyoto Protocol is an international treaty adopted in Kyoto, Japan, in December 1997 under the United Nations Framework Convention on Climate Change (UNFCCC). Its primary objective is to address global warming by committing industrialized countries and economies in transition to limit and reduce greenhouse gas emissions in accordance with agreed individual targets. The protocol targets gases such as carbon dioxide, methane, nitrous oxide, and fluorinated gases, which trap heat in the atmosphere and drive global climate change.

Explanation

During the cabinet reshuffle of the National Democratic Alliance (NDA) government led by Prime Minister Atal Bihari Vajpayee on September 1, 2001, Mr. Jagmohan was shifted from the Ministry of Urban Development and Poverty Alleviation to the Ministry of Tourism (which was later combined with Culture).

Explanation

During the Delhi Sultanate period, Sultan Shamsuddin Iltutmish formalized the monetary system by introducing two key standard coins: the silver Tanka and the copper Jital. The silver Tanka, weighing approximately 175 grains, served as the primary high-value currency, while the copper Jital was used for smaller, everyday transactions.

Later, Firoz Shah Tughlaq expanded this system by introducing several fractional silver coins to facilitate trade. One such coin was the Shasgaini, which was a silver coin equivalent in value to six jitals. Consequently, the Jital was made of copper, the Shasgaini was made of silver, and the Tanka was made of silver.

Explanation

The Pleistocene epoch, spanning from approximately 2.58 million years ago to 11,700 years ago, is characterized by repeated glacial cycles. The most recent Ice Age, also known as the Pleistocene or Quaternary glaciation, was initiated at the onset of this epoch, during which large continental ice sheets repeatedly advanced and retreated over extensive regions of the Earth.

Explanation

The positions of the letters in the English alphabetical order are: E = 5 G = 7 J = 10 N = 14 S = 19

The pattern of differences between consecutive terms is: 7 - 5 = 2 10 - 7 = 3 14 - 10 = 4 19 - 14 = 5

The difference increases by 1 at each step. Following this arithmetic progression, the next difference is 6. Adding 6 to the numerical position of S gives 19 + 6 = 25, which represents the letter Y.

Explanation

During the late 1990s and early 2000s, India's economic expansion and industrial growth were heavily bottlenecked by a severe deficit in physical infrastructure. Inadequate and unreliable power supply, poorly connected road networks, congested ports, and outdated railway systems significantly increased transaction costs and diminished the global competitiveness of Indian businesses. Addressing these infrastructural deficiencies was identified as the topmost priority in both the Ninth and Tenth Five-Year Plans to sustain high economic growth and attract foreign investments.

He was a prominent intellectual, educator, and political leader who co-founded the Indian National Congress, serving as its President three times, in 1886, 1893, and 1906. He is best known for formulating the Drain Theory in his book Poverty and Un-British Rule in India, which detailed how British policies systematically drained India of its wealth. Additionally, he became the first Indian to be elected as a Member of Parliament in the British House of Commons, representing the Liberal Party.

Explanation

The National Emergency in India has been proclaimed under Article 352 of the Constitution on three occasions:

The first proclamation was made in October 1962 during the Indo-China war, when the security of India was threatened by external aggression. This emergency remained in force until January 1968.

The second proclamation was issued in December 1971 during the Indo-Pakistan war, also on the grounds of external aggression.

The third proclamation was made in June 1975 on the grounds of internal disturbance, under controversial circumstances during the premiership of Indira Gandhi. Both the second and third emergencies were revoked simultaneously in March 1977.

Explanation

K. Padmanabhaiah, a former Union Home Secretary, served as the Government of India's official emissary and interlocutor for the Naga peace talks. On June 14, 2001, he negotiated and signed the ceasefire extension agreement with the leadership of the National Socialist Council of Nagaland - Isak Muivah (NSCN-IM) in Bangkok. The agreement, which extended the ceasefire beyond the geographical boundaries of Nagaland under the clause "without territorial limits," was negotiated directly by him on behalf of the central government.

Explanation

Salivary glands are classified as exocrine glands rather than endocrine glands because they secrete saliva, containing enzymes like amylase, through a system of ducts directly onto an epithelial surface in the oral cavity. Endocrine glands are ductless glands that secrete chemical messengers, known as hormones, directly into the bloodstream to act on distant target organs. Because salivary glands rely on ducts to transport their secretions to a specific localized area instead of releasing hormones into the circulatory system, they do not function as endocrine glands.

Explanation

The historic 30-year treaty on sharing the Ganga waters at Farakka was signed on December 12, 1996, by the Prime Minister of India, H. D. Deve Gowda, and the Prime Minister of Bangladesh, Sheikh Hasina.

Explanation

To find the off-day, we can map each day of the week from Monday to Sunday.

Monday is visited as C. Tuesday is visited as B, since B is visited on the day following C. Friday is visited as F. Sunday is visited as D.

The remaining vacant days are Wednesday, Thursday, and Saturday. The remaining items to place are area A, area E, and the off-day.

We are given that area A is visited on a day ahead of area E. This means A must be visited on a day preceding E. Furthermore, E cannot be visited on the day following F. Since Friday is F, the day following F is Saturday, which means E cannot be visited on Saturday.

If the off-day were Wednesday or Thursday, E would have to be visited on Saturday to keep A ahead of E, which violates the given condition. Therefore, E must be visited on Thursday, and A must be visited on Wednesday. This leaves Saturday as the only possible slot for the off-day.

Explanation

Part XVIII of the Constitution of India, spanning Articles 352 to 360, outlines three distinct types of emergencies designed to safeguard the sovereignty, unity, integrity, and security of the country.

This landmark conference led to the adoption of the Durban Declaration and Programme of Action, which created a comprehensive framework to combat racism, racial discrimination, and xenophobia globally.

Explanation

Refrigeration works by lowering the temperature of the food environment. According to chemical kinetics, the rate of biochemical and enzymatic reactions within food and contaminating micro-organisms is highly temperature-dependent. A decrease in temperature lowers the kinetic energy of the reacting molecules, thereby exponentially reducing the rate of these metabolic and spoilage-causing biochemical reactions. This slows down the decomposition of food and inhibits the rapid growth of bacteria, effectively preserving the food for a longer duration.

Explanation

Yellow light has a longer wavelength compared to blue and violet lights. According to Rayleigh's scattering law, the intensity of scattered light is inversely proportional to the fourth power of its wavelength:

I ∝ (1)/(λ⁴)

Because of this, shorter wavelengths are scattered much more easily by water droplets and dust particles in fog, creating a blinding glare or backscatter for the driver. Yellow light, having a longer wavelength, undergoes significantly less scattering and can penetrate through the fog more effectively, thereby illuminating the road better during foggy nights and reducing glare.

Explanation

Sopara, historically known as Shurparaka, was one of the most prominent ancient port cities and trade centers on the western coast of India.

Explanation

Dadabhai Naoroji, widely known as the Grand Old Man of India, formulated the Drain of Wealth theory to explain how a large part of India's resources and national wealth were systematically exported to Britain without any equivalent economic or material return. He first propounded this theory in 1867 in a paper titled England's Debt to India, which he presented before the East India Association in London. He later expanded this analysis in his landmark book Poverty and Un-British Rule in India, demonstrating how colonial financial mechanisms and unilateral transfers of capital were the primary cause of India's poverty.

Explanation

Silver has the highest electrical and thermal conductivity of all known metals. This exceptional conductive ability is due to its unique crystalline structure and the presence of a single, highly mobile valence electron in its outermost shell. These free electrons are able to move through the metallic lattice with extremely low resistance, facilitating the rapid transfer of both electric charge and thermal energy.

Explanation

Abdur Razzaq, a Persian scholar and ambassador of the Timurid dynasty ruler Shah Rukh, visited the Vijayanagara Empire in 1443 AD during the reign of Devaraya II. He wrote a detailed travelogue, Matla-us-Sadain wa Majma-ul-Bahrain, which provides a vivid description of the wealth, grandeur, and administrative structure of the Vijayanagara kingdom, particularly praising the defense architecture of the capital city.

Explanation

Krishnadevaraya, the prominent ruler of the Vijayanagara Empire, wrote his masterpiece Amuktamalyada in Telugu. It is an epic poem that narrates the story of the Alvar poet-saint Andal, also known as Goda Devi, and her intense devotion to Lord Ranganatha. The work is highly revered as one of the Panchakavyas, or five great books, of Telugu literature. It reflects not only deep religious devotion but also includes significant sections on statecraft, polity, and administrative guidelines for a king.

Explanation

The Treaty of Purandar was signed on June 11, 1665, between Chhatrapati Shivaji Maharaj and Rajput ruler Raja Jai Singh I, who was representing the Mughal Emperor Aurangzeb. Jai Singh was appointed by the Mughal court to lead a massive force to besiege the Maratha territories and curb Shivaji's expansion. Following a successful siege of the Purandar fort by the Mughal forces, Shivaji was compelled to enter negotiations. Under the terms of this treaty, Shivaji surrendered 23 of his forts to the Mughals, retaining only 12 for himself, and agreed to assist the Mughals in their military campaign against the Deccan Sultanate of Bijapur.

Explanation

Diphtheria is an acute, highly infectious disease caused by the bacterium Corynebacterium diphtheriae. The bacteria primarily infect the mucous membranes of the nose and throat, releasing a powerful toxin that can cause severe tissue damage. This toxin leads to the formation of a characteristic thick, gray coating or pseudomembrane in the throat, which can cause breathing difficulties, airway obstruction, and systemic complications such as myocarditis and neuropathy. Transmission typically occurs through respiratory droplets from coughing or sneezing, or through direct contact with secretions or open sores of an infected person.

Explanation

Madam Bhikhaji Cama hoisted the first version of the Indian national flag on August 22, 1907, at the International Socialist Congress held in Stuttgart, Germany. This flag, designed by her along with other revolutionaries, featured three horizontal stripes of green, saffron, and red, representing different religions of India, with eight lotuses representing the eight provinces of British India, and the words Vande Mataram inscribed in the center in Devanagari script.

Explanation

The Rowlatt Act, officially known as the Anarchical and Revolutionary Crimes Act of 1919, was passed by the Imperial Legislative Council in March 1919. Named after Sir Sidney Rowlatt, the president of the Rowlatt Committee, this legislation authorized the British colonial administration to imprison any person suspected of terrorism or revolutionary activities for up to two years without trial. The act suspended the right of habeas corpus and allowed for preventive indefinite detention, which led to widespread protests across India and the launch of the Rowlatt Satyagraha by Mahatma Gandhi.

Explanation

Chhattisgarh was officially granted statehood on 1 November 2000, when it was partitioned from the southeastern region of Madhya Pradesh. The creation of this new state was enacted under the Madhya Pradesh Reorganisation Act, 2000, passed by the Parliament of India, which established Chhattisgarh as the 26th state of the Indian Union.

Explanation

An antecedent river is one that existed before the current topographic barrier, such as a mountain range, was uplifted. As the Himalayas rose, the Indus River maintained its pre-existing course by continuously eroding its bed at a rate equal to or faster than the rate of tectonic uplift. This intense downcutting resulted in the formation of deep, steep-sided gorges. Since the Indus River established its path prior to the main phase of Himalayan mountain-building and cut through the rising ranges, it is classified as an antecedent river.

Explanation

An estuarine delta is a type of delta that forms at the submerged mouth of a river within an estuary. In these systems, sediment deposition occurs primarily along the shallow sides of the estuary or tidal inlets rather than building out dramatically into the open sea. The Rhine River, upon entering the North Sea, forms the Rhine-Meuse-Scheldt delta, which is a classic example of an estuarine delta. The river's mouth is deeply affected by tidal activity, and sediment accumulates within the pre-existing, submerged estuarine channels and basins, creating a complex network of brackish tidal estuaries and deltaic plains.

Explanation

Let the three numbers be 2x, 3x, and 7x. Since the ratio terms 2, 3, and 7 are pairwise co-prime, the L.C.M. of the numbers is the product of these co-prime terms and their common factor x:

L.C.M. = 2 × 3 × 7 × x = 42x

Equating this to the given L.C.M. of 714:

42x = 714

x = 17

The greatest number is represented by the largest ratio term, which is 7x:

7 × 17 = 119

Explanation

Let the daily wages of the two workers be 3x and 4x.

The difference between their daily wages is given as Rs. 12. This relation can be written as: 4x - 3x = 12 x = 12

The total daily wage earned by both workers combined is: 3x + 4x = 7x

Substituting the value of x: 7 × 12 = 84

The total daily wage of both workers is Rs. 84.

Explanation

Using the standard work-rate formula:

M₁ · D₁ · H₁ = M₂ · D₂ · H₂

where M represents the number of men, D represents the number of days, and H represents the working hours per day.

Substituting the given values into the equation:

10 · 6 · 8 = 6 · D₂ · 5

480 = 30 · D₂

D₂ = ⁴⁸⁰⁄₃₀ = 16

Explanation

Let the total surface area of the Earth be 30 units. Since the Earth is divided into two equal hemispheres, the area of both the Northern Hemisphere and the Southern Hemisphere is 15 units each.

For the entire globe, the ratio of land to water is 1:2. Total Land = ⅓ × 30 = 10 units Total Water = ⅔ × 30 = 20 units

For the Northern Hemisphere, the ratio of land to water is 2:3, and the total area is 15 units. Land in Northern Hemisphere = ⅖ × 15 = 6 units Water in Northern Hemisphere = ⅗ × 15 = 9 units

Subtracting these values from the global totals yields the land and water distribution in the Southern Hemisphere: Land in Southern Hemisphere = 10 - 6 = 4 units Water in Southern Hemisphere = 20 - 9 = 11 units

Taking the ratio of land to water in the Southern Hemisphere gives 4:11.

Explanation

Let the total savings of the man be S. Since he leaves 35% of his savings to each of his two sons, the combined share of the two sons is 2 × 35% = 70%.

The rest of the savings go to his wife, which is equal to: 100% - 70% = 30%

Given that the wife receives Rs. 4332, we can set up the equation: 30% of S = 4332

³⁰⁄₁₀₀ × S = 4332

S = (4332 × 100)/(30)

S = 14440

Explanation

Let the capacity of the cistern be represented as 1 unit.

The emptying rate of the outlet pipe is 1/60 of the cistern per minute.

When the outlet pipe and the leak work together, the cistern is emptied in 45 minutes, meaning their combined emptying rate is 1/45 of the cistern per minute.

The rate of the leak is the difference between the combined rate and the rate of the outlet pipe:

Rₗₑₐₖ = 1/45 - 1/60

Taking the least common multiple of 45 and 60, which is 180:

Rₗₑₐₖ = (4 - 3) / 180 = 1/180 of the cistern per minute.

The leak alone can empty the full cistern in 180 minutes. Converting this to hours:

180 / 60 = 3 hours.

Explanation

When a value A is r% greater than another value B, then B is lower than A by the standard percentage relation:

Percentage lower = (r)/(100 + r) × 100 %

Substituting r = 50 into the formula:

Percentage lower = (50)/(100 + 50) × 100 % = ⁵⁰⁄₁₅₀ × 100 % = ⅓ × 100 % = 33⅓%
