Explanation

The differences between consecutive terms in the series are: 6 - 2 = 4 12 - 6 = 6 20 - 12 = 8 30 - 20 = 10

This forms a sequence of consecutive even numbers: 4, 6, 8, 10. Following this pattern, the next difference must be 12. Adding 12 to the preceding term 30 gives:

30 + 12 = 42

Thus, the correct term after 30 should be 42 instead of 40, making 40 the wrong term in the series.

Explanation

The given number series represents the squares of consecutive even numbers starting from 2:

2² = 4 4² = 16 6² = 36 8² = 64 10² = 100 12² = 144

Following this pattern, the next term must be 14² = 196. Because the term given in the series is 200, it is the incorrect term.

Let the set of freshmen be represented by F, the set of students by S, and the set of humans by H. Statements I and II can be represented in set notation as F ⊆ H and S ⊆ H respectively. This indicates that both freshmen and students are subsets of the set of humans.

From these two premises alone, no definitive relation can be established between freshmen (F) and students (S); they may be disjoint, overlapping, or one may be a subset of the other. Therefore, statement (1) does not logically follow. Furthermore, since the concept of "thinking" is not introduced or defined in statements I and II, no logical conclusions regarding who thinks or does not think can be drawn. This means statements (2), (3), and (4) cannot be logical consequences of statements I and II. Consequently, none of the given statements is a logical consequence of I and II only.

Explanation

The Ten Degree Channel is a channel that separates the Andaman Islands and Nicobar Islands from each other in the Bay of Bengal. This latitude channel is approximately 150 kilometers wide from east to west and lies closely along the 10-degree N parallel of latitude, which gives it its name. It serves as a major maritime passage connecting the Bay of Bengal with the Andaman Sea.

Explanation

Marusthali is the name given to the extremely arid, sand-dune-covered region of the Thar Desert, situated primarily in the western part of Rajasthan. The term is derived from Sanskrit, where maru means desert or dead and sthali means land, translating literally to the land of the dead. This physiographic region is characterized by low annual precipitation of less than 25 cm, high evaporation rates, shifting sand dunes locally referred to as dhrians, and xerophytic vegetation that is well-adapted to severe water stress.

Explanation

English was officially announced as the medium of instruction for education in India through the English Education Act of 1835. This major policy decision was shaped by Thomas Babington Macaulay, who presented his famous Minute on Indian Education in February 1835, advocating for Western-style education and the English language. Lord William Bentinck, the Governor-General of India, formally accepted Macaulay's recommendations and passed the resolution on March 7, 1835, directing that government funds for education be spent on English-medium instruction.

Explanation

Myopia, commonly known as nearsightedness, is a refractive error where a person can see near objects clearly but distant objects appear blurry. This occurs because the parallel light rays coming from a distant object are focused in front of the retina instead of directly on its surface, which is typically caused by an elongated eyeball or excessive curvature of the eye lens.

To correct myopic vision, a concave lens of a suitable focal length is used. Since a concave lens is a diverging lens, it diverges the incoming parallel light rays before they reach the eye lens. This preliminary divergence allows the eye lens to focus the light rays further back, precisely on the retina, thereby restoring clear distance vision.

Explanation

Rice is the most dominant crop and the principal food grain of West Bengal, occupying approximately 70% of the net cultivated area of the state. The agro-climatic conditions of West Bengal, characterized by fertile alluvial soils, hot and humid climate, and high annual rainfall, are exceptionally favorable for paddy cultivation. The crop is grown in three different seasons as Aman (winter rice), Aus (autumn rice), and Boro (summer rice), making the state the leading producer of rice in India.

Explanation

West Bengal is the largest rice-producing state in India. The favorable tropical monsoon climate, abundant rainfall, and fertile alluvial soil of the Ganga-Brahmaputra delta make the region highly suitable for paddy cultivation. Rice is grown across three distinct seasons: Aus, Aman, and Boro.

Much of this work was carried out through the Carter Center, a non-governmental organization he founded in 1982 to advance human rights and alleviate human suffering worldwide.

Explanation

The Narmada River is one of the major peninsular rivers in India that flows westwards. It originates from the Amarkantak Plateau in Madhya Pradesh. The river flows through a rift valley between the Vindhya Range on the north and the Satpura Range on the south, eventually emptying into the Arabian Sea through the Gulf of Khambhat in Gujarat. This westward flow is dictated by the structural faulting in the region rather than the general eastward slope of the Deccan Plateau.

Explanation

The Sun generates its energy through nuclear fusion reactions occurring in its core. Under the extreme temperatures and pressures at the core of the Sun, lighter hydrogen nuclei (protons) combine to form heavier helium nuclei. This process is primarily governed by the proton-proton chain reaction. During this fusion process, a small fraction of mass is lost and converted into a massive amount of energy, as described by Einstein's mass-energy equivalence equation, E = mc². This released energy travels outwards and is emitted from the Sun's surface as electromagnetic radiation, providing light and heat to the solar system.

Explanation

The Second Five-Year Plan (1956–1961), formulated by Prasanta Chandra Mahalanobis, focused heavily on rapid industrialisation.

Explanation

Annie Besant founded the All India Home Rule League in September 1916 in Madras. Inspired by the Irish Home Rule movement, her league aimed to achieve self-government for India within the British Empire through constitutional means. The All India Home Rule League had a wide geographical reach, establishing branches across most of India except for areas like Bombay presidency and Karnataka, which were covered by Bal Gangadhar Tilak's league. It utilized public meetings, local discussions, and pamphlets to mobilize national consciousness and demand home rule.

Explanation

The dry western regions of Rajasthan, which lie to the west of the Aravalli range and constitute the core of the Thar Desert, experience an extremely arid climate. These hyper-arid areas, particularly districts such as Jaisalmer, receive an average annual rainfall of less than 20 cm, with Jaisalmer itself recording the lowest at approximately 17 cm.

Explanation

The given sequence is an alternating series composed of two distinct geometric progressions.

The terms at the odd positions (1st, 3rd, 5th, and 7th) follow the pattern of powers of 2: 2¹ = 2 2² = 4 2³ = 8 2⁴ = 16

The terms at the even positions (2nd, 4th, and 6th) follow the pattern of powers of 3: 3¹ = 3 3² = 9 3³ = 27

Since the missing term is the seventh number in the sequence, it corresponds to the next term in the first series, which is 2⁴ = 16.

Explanation

The terms of the given sequence follow the mathematical relation: aₙ = 3ⁿ - n³

Let us verify this pattern for the first six terms: For n = 1: 3¹ - 1³ = 3 - 1 = 2 For n = 2: 3² - 2³ = 9 - 8 = 1 For n = 3: 3³ - 3³ = 27 - 27 = 0 For n = 4: 3⁴ - 4³ = 81 - 64 = 17 For n = 5: 3⁵ - 5³ = 243 - 125 = 118 For n = 6: 3⁶ - 6³ = 729 - 216 = 513

For the seventh term (n = 7), the formula mathematically yields: 3⁷ - 7³ = 2187 - 343 = 1844

In the context of the examination paper, a computational slip in evaluating 7³ as 483 (instead of 343) leads to the following result: 2187 - 483 = 1704

This matches the option.

Explanation

The gravitational force is the weakest of the four fundamental forces of nature. According to Newton's law of universal gravitation, the force is given by:

F = G (m₁ m₂)/(r²)

where G is the universal gravitational constant, which has an extremely small value of 6.674 × 10⁻¹¹ N m²/kg². This exceptionally small coupling constant means that the gravitational force between everyday objects or subatomic particles is virtually negligible. Its relative strength is approximately 10⁻³⁹ times that of the strong nuclear force, making it the weakest force despite having an infinite range. It only becomes prominent on astronomical scales due to the massive accumulation of matter.

Explanation

Duns are longitudinal structural valleys formed as a result of folding during the collision of the Eurasian and Indian tectonic plates. They lie between the Lesser Himalayas and the Shiwalik range. These valleys are filled with coarse alluvial sediments brought down by the Himalayan rivers, resulting in flat-bottomed longitudinal valleys. Examples of such formations include Dehradun, Kotli Dun, and Patli Dun.

In 1929, he founded the Khudai Khidmatgar, a non-violent movement that actively opposed British rule.

Explanation

Owls possess forward-facing eyes, which is a distinct characteristic among birds. This anatomical arrangement allows the fields of vision of both eyes to overlap significantly, resulting in a high degree of binocular or stereoscopic vision. Just like in humans, this binocular vision enables owls to perceive objects in three dimensions—incorporating height, width, and depth—and provides excellent depth perception to judge distances accurately. This shared evolutionary adaptation for spatial and depth perception is why the owl has a highly similar visual processing mechanism to humans.

Explanation

The Kaveri river water dispute is a long-standing conflict primarily between the upper riparian state of Karnataka and the lower riparian state of Tamil Nadu. The genesis of the dispute lies in two bilateral agreements signed in 1892 and 1924 between the erstwhile Madras Presidency and the Kingdom of Mysore. Karnataka contends that these colonial-era agreements were heavily skewed in favor of Madras, while Tamil Nadu argues that it has a historical right to the waters to sustain its highly developed agricultural sector in the fertile Kaveri delta region.

Explanation

Sri Chaitanyadeva (1486–1534), the great Vaishnava saint and founder of Gaudiya Vaishnavism, flourished during the reign of Alauddin Husain Shah, who ruled Bengal from 1494 to 1519. Husain Shah's tenure was marked by a policy of religious tolerance. When Chaitanyadeva's bhakti movement and congregational chanting (sankirtan) gained immense popularity among the masses, the Sultan issued orders to his administrators and qazis to ensure that Chaitanyadeva was not harassed and was allowed to preach freely. Additionally, two of Husain Shah's most prominent state ministers, Dabir-i-Khas and Sakar Mallik, became ardent disciples of Chaitanyadeva and were renamed Rupa Goswami and Sanatana Goswami, going on to become key theologians of the Gaudiya Vaishnava tradition.

Explanation

Titumir, born Mir Nisar Ali, was a prominent leader of the Wahabi movement in Bengal during the early nineteenth century. He was deeply influenced by Syed Ahmad Barelvi, the pioneer of the Wahabi movement in India, during his pilgrimage to Mecca. Upon his return, Titumir spearheaded a socio-religious reform movement among the Muslim peasantry of Bengal, which soon transformed into a peasant rebellion against the oppressive exactions of local zamindars and British indigo planters. He is famously remembered for constructing a bamboo fortress, known as Bansher Kella, in Narkelberia, where he and his followers put up a historic resistance against the British military forces in 1831.

Explanation

For an ideal transformer, the electrical power is conserved between the primary and secondary windings, which is expressed by the relation:

P = Vₚ Iₚ = Vₛ Iₛ

where Vₚ and Vₛ are the primary and secondary voltages, and Iₚ and Iₛ are the primary and secondary currents, respectively.

A step-down transformer decreases the voltage from the primary to the secondary side, such that:

Vₛ < Vₚ

To maintain the conservation of power, the relationship between the currents is given by:

Iₛ = Iₚ ( (Vₚ)/(Vₛ) )

Since the ratio of the primary voltage to the secondary voltage is greater than one, the secondary current is greater than the primary current. This results in an increase in current on the output side of the step-down transformer.

Explanation

Under Article 356 of the Constitution of India, if the President, on receipt of a report from the Governor of a State or otherwise, is satisfied that a situation has arisen in which the government of the State cannot be carried on in accordance with the provisions of the Constitution, the President may by Proclamation assume to himself all or any of the functions of the Government of the State.

Explanation

The coding scheme replaces each letter of the alphabet with its corresponding letter in the reverse alphabetical order. This relationship can be represented by the formula:

Position of coded letter = 27 - Position of original letter

Applying this formula to each letter of the word CALCUTTA:

C with position 3 is coded as X with position 24.

A with position 1 is coded as Z with position 26.

L with position 12 is coded as O with position 15.

C with position 3 is coded as X with position 24.

U with position 21 is coded as F with position 6.

T with position 20 is coded as G with position 7.

T with position 20 is coded as G with position 7.

A with position 1 is coded as Z with position 26.

Combining these coded letters gives XZOXFGGZ.

Explanation

In this coding scheme, each letter of the word is replaced by its opposite letter in the standard English alphabet, where the sum of the numerical positions of the original letter and its coded letter is always 27.

Applying this rule to the word PRESIDENCY: P, which is the 16th letter, is replaced by K, which is the 11th letter (16 + 11 = 27). R, which is the 18th letter, is replaced by I, which is the 9th letter (18 + 9 = 27). E, which is the 5th letter, is replaced by V, which is the 22nd letter (5 + 22 = 27). S, which is the 19th letter, is replaced by H, which is the 8th letter (19 + 8 = 27). I, which is the 9th letter, is replaced by R, which is the 18th letter (9 + 18 = 27). D, which is the 4th letter, is replaced by W, which is the 23rd letter (4 + 23 = 27). E, which is the 5th letter, is replaced by V, which is the 22nd letter (5 + 22 = 27). N, which is the 14th letter, is replaced by M, which is the 13th letter (14 + 13 = 27). C, which is the 3rd letter, is replaced by X, which is the 24th letter (3 + 24 = 27). Y, which is the 25th letter, is replaced by B, which is the 2nd letter (25 + 2 = 27).

This yields the code KIVHRWVMXB.

Explanation

In the word AIRPORT, the letter R is repeated at the third and sixth positions, while all other letters (A, I, P, O, T) are unique. In a substitution cipher where each letter of the alphabet is replaced by another letter, the corresponding code must maintain this exact pattern of letter repetition. The code QOSMRSZ contains the letter S at the third and sixth positions, while all other letters in the code (Q, O, M, R, Z) are unique, perfectly matching the structural pattern of the original word.

Explanation

Rabindranath Tagore is a legendary poet, writer, philosopher, and artist who is celebrated for his profound contributions to literature, music, and the arts, for which he was awarded the Nobel Prize in Literature in 1913.

Explanation

In India, the determination of the poverty line has traditionally been based on the minimum nutritional requirements of the population. The Task Force on Projections of Minimum Needs and Effective Consumption Demand, constituted in 1979 under the chairmanship of Y. K. Alagh, defined the poverty line using calorie consumption. It recommended a daily consumption of 2400 calories per capita in rural areas and 2100 calories per capita in urban areas. The monetary value of this minimum food basket, alongside essential non-food items, was calculated to estimate the poverty line. This calorie-intake-based methodology was also adopted by the subsequent Lakdawala Committee in 1993 to determine poverty estimates across states.

Explanation

Under Article 324(5) of the Constitution of India, the Chief Election Commissioner is provided with security of tenure and cannot be removed from office except in like manner and on the like grounds as a Judge of the Supreme Court. This removal process requires an address supported by a special majority—a majority of the total membership of each House of Parliament and a majority of not less than two-thirds of the members present and voting—to be presented to the President in the same session on the grounds of proved misbehaviour or incapacity, after which the President issues the formal order of removal.

Explanation

Variable cost represents the expenses that vary directly and proportionally with the level of output. As the volume of production increases, the requirement for essential inputs such as raw materials, fuel, and direct labor rises progressively. Consequently, the total variable cost increases continuously at every successive level of production, starting from zero when there is no output.

Explanation

Water exhibits an anomalous expansion behavior between 0°C and 4°C. At 4°C, water has its maximum density and minimum volume. When water cools from 7°C to 4°C, it behaves normally, contracting as its temperature drops and volume decreases. However, as it is cooled further from 4°C to 1°C, it expands anomalously, causing its volume to increase. Thus, during the cooling process from 7°C to 1°C, water first contracts and then expands.

Explanation

The Panchayati Raj system was first introduced in Nagaur district of Rajasthan on October 2, 1959, by the then Prime Minister Jawaharlal Nehru. This initiative was based on the recommendations of the Balwant Rai Mehta Committee, appointed in 1957, which proposed a three-tier democratic decentralization system consisting of Gram Panchayats at the village level, Panchayat Samitis at the block level, and Zilla Parishads at the district level.

Explanation

Gurukul Kangri Vishwavidyalaya was founded on March 2, 1902, by Swami Shraddhanand, who was a prominent disciple of Swami Dayanand Saraswati and a leader of the Arya Samaj. The institution was established at Kangri near Hardwar on the banks of the Ganges to revive the ancient Vedic gurukul system of education. It was designed to provide an indigenous alternative to the colonial British education system, combining traditional Vedic instruction, Sanskrit literature, and Indian philosophy with modern science and English.

Explanation

The Constitution of India contains twelve schedules. While the original Constitution adopted in 1949 consisted of eight schedules, four additional schedules were incorporated over the years through various constitutional amendments. The Ninth Schedule was added by the First Constitutional Amendment Act of 1951 to protect land reform laws from judicial review. The Tenth Schedule, containing provisions relating to disqualification on the ground of defection, was added by the Fifty-Second Constitutional Amendment Act of 1985. The Eleventh Schedule, specifying the powers, authority, and responsibilities of Panchayats, was added by the Seventy-Third Constitutional Amendment Act of 1992. The Twelfth Schedule, detailing the powers, authority, and responsibilities of Municipalities, was added by the Seventy-Fourth Constitutional Amendment Act of 1992. This brought the total number of schedules to twelve.

Explanation

In 2003, when this exam was conducted, Courtney Walsh held the record for the most wickets in Test cricket with 519 wickets. Muthiah Muralitharan surpassed Walsh's record in 2004, and Shane Warne did so in 2005.

Explanation

The word Mansab is of Arabic origin and literally means rank, position, or office. In the Mughal administration, particularly under the Mansabdari system introduced by Akbar, it designated the official status, salary scale, and military obligations of government officials and military commanders within the imperial hierarchy.

Explanation

The Green Revolution, introduced in India in the late 1960s, achieved its most spectacular success in wheat cultivation through the adoption of High-Yielding Variety seeds, chemical fertilizers, and modern irrigation, which dramatically increased the productivity of wheat. However, because these capital-intensive inputs were highly concentrated in naturally well-irrigated regions like Punjab, Haryana, and Western Uttar Pradesh, it led to a significant rise in regional inequalities, leaving drier and less-endowed regions lagging behind. Furthermore, since only wealthy landowners could afford the expensive seeds, fertilizers, and machinery required for this new technology, it widened the socio-economic gap between rich and poor farmers, thereby increasing inter-personal inequalities in rural areas.

Explanation

The University of Calcutta was established on 24 January 1857 under the Calcutta University Act, 1857. Sir James William Colvile, who was then the Chief Justice of the Supreme Court of Judicature in Bengal, was appointed as its first Vice-Chancellor. He served in this honorary capacity for two years from 24 January 1857 to 24 January 1859, while Governor-General Lord Canning served as the first Chancellor of the university.

Explanation

Under Article 280 of the Constitution of India, the President constitutes the Finance Commission every five years or earlier. The primary duty of this constitutional body is to recommend the distribution of net proceeds of taxes between the Union and the States, and the allocation among the States of the respective shares of such proceeds. It also determines the principles that govern the grants-in-aid of the revenues of the States out of the Consolidated Fund of India. This constitutional mechanism ensures a structured, balanced, and periodic review of the fiscal relations between the Centre and the States.

Explanation

Nil-Darpan, meaning The Mirror of Indigo, is a landmark Bengali play written by Dinabandhu Mitra in 1858–1859 and published in Dhaka in 1860. The play vividly depicted the brutal exploitation, coercion, and torture faced by the local peasantry at the hands of British indigo planters in Bengal during the Indigo Revolt. It succeeded in drumming up immense public support and empathy for the farmers, serving as a powerful tool of social commentary and political awakening. The English translation of the play, published by Reverend James Long, further amplified this cause globally.

Explanation

The weight of an object is given by the formula W = mg, where m is the mass of the object and g is the acceleration due to gravity. The effective acceleration due to gravity at any latitude θ on the Earth's surface is given by the relation:

g_θ = g₀ - Rω² cos²θ

where R is the radius of the Earth and ω is the angular velocity of its rotation. At the poles, the latitude is θ = 90°, which reduces the centrifugal term Rω² cos²θ to zero. Additionally, because the Earth is an oblate spheroid, the polar radius is smaller than the equatorial radius. According to Newton's law of gravitation, gravitational acceleration is inversely proportional to the square of the distance from the center of the Earth:

g ≈ (GM)/R²

The smaller radius at the poles increases the gravitational pull. Both the lack of centrifugal force and the shorter distance to the center of the Earth maximize the value of g at the poles, which results in the maximum weight for a man at these locations.

Explanation

Article 18 of the Constitution of India relates to the abolition of titles. Clause 1 of Article 18 prevents the State from conferring any title except military or academic distinctions. The Government of India instituted National Awards, including the Bharat Ratna and Padma Shri, under the premise of academic and meritorious distinctions. The Supreme Court of India subsequently upheld the constitutional validity of these awards, ruling that they are decorations recognizing merit and do not amount to titles within the meaning of Article 18, as long as they are not used as prefixes or suffixes to the names of the recipients.

Explanation

As an economy transitions from developing to developed, it undergoes a structural shift characterized by the Clark-Fisher hypothesis. Economic progress leads to a reallocation of labor where the service or tertiary sector becomes the dominant contributor to both economic output and employment, as rising incomes increase the demand for services such as banking, education, healthcare, and information technology.

Explanation

The Laccadive Islands, renamed Lakshadweep in 1973, are situated in the Arabian Sea off the southwestern coast of India and are entirely of coral origin. They consist of numerous low-lying atolls, coral reefs, and islands that have developed through the accumulation of calcium carbonate skeletons deposited by marine organisms known as coral polyps over millions of years. These polyps thrived on the shallow submarine platforms of the Chagos-Laccadive Ridge, gradually building up the landmasses to form classic coral islands.

Explanation

Brussels, Belgium, serves as the de facto headquarters of the European Union. It hosts the key institutions of the EU, including the European Commission, the Council of the European Union, and a seat of the European Parliament, making it the administrative center of the union.

Explanation

Guru Tegh Bahadur was the ninth Sikh Guru who led the Sikh community from 1665 until his death in 1675. His period of leadership directly coincided with the reign of the Mughal Emperor Aurangzeb, who ruled from 1658 to 1707. Guru Tegh Bahadur championed religious freedom and strongly opposed the policy of forced religious conversions pursued during Aurangzeb's reign, particularly defending the rights of Kashmiri Pandits. This conflict led to his arrest and subsequent execution in Delhi in 1675 on Aurangzeb's orders.

Explanation

Gandhara art flourished extensively during the Kushana period, particularly under the patronage of Emperor Kanishka in the first and second centuries CE. This unique school of art developed in the northwestern frontier of ancient India, combining Greek and Roman artistic techniques with Buddhist themes, earning it the designation of Greco-Buddhist art. The Kushana rulers provided immense patronage to Buddhism, facilitating the creation of the earliest anthropomorphic sculptures of the Buddha characterized by realistic musculature, wavy hair, and heavy, folded drapery reminiscent of Roman togas.

Explanation

The Tripura Highland region possesses highly favorable sub-tropical agro-climatic conditions, fertile slightly acidic soil, and abundant rainfall, which are ideally suited for rain-fed horticulture. This makes the region one of the leading producers of high-quality pineapple varieties, such as the GI-tagged Queen pineapple and the Kew variety, on an extensive scale. Additionally, the arid regions of Jodhpur and Jaisalmer in West Rajasthan experience some of the highest solar insolation in India with an exceptionally high number of clear, sunny days throughout the year, making them highly ideal for the development of solar energy projects.

Explanation

The Thar Desert region, including Jodhpur and Jaisalmer, is highly ideal for the development of solar energy due to its geographical and climatic conditions. This region receives some of the highest levels of annual solar radiation in India, averaging between 6 to 7 kWh/m² per day. It benefits from an exceptionally high number of clear, cloudless sunny days, typically exceeding 300 to 325 days a year, coupled with very low average rainfall. Additionally, the availability of vast, flat, and sparsely populated arid desert land provides the perfect topography for installing large-scale solar photovoltaic panels and solar thermal plants.

Explanation

The Third Five-Year Plan (1961–1966) faced severe economic shocks, including the Sino-Indian War of 1962, the Indo-Pakistani War of 1965, and a devastating agricultural drought in 1965–1966. These crises led to a severe depletion of financial resources, rising inflation, and a foreign exchange crisis, which forced the government to temporarily suspend the long-term planning process. Consequently, the formulation of the Fourth Five-Year Plan was deferred, and three consecutive Annual Plans were implemented from 1966 to 1969. This three-year gap in medium-term planning is officially designated as the Plan Holiday.

Explanation

According to Rayleigh scattering law, the intensity of scattered light is inversely proportional to the fourth power of its wavelength:

I ∝ (1)/(λ⁴)

Because blue light has a shorter wavelength than most other colours in the visible spectrum, it is scattered much more strongly by the gas molecules in the Earth's atmosphere. This highly scattered blue light is directed in all directions across the sky, which causes the sky to appear blue to an observer on the ground.
