Question 2General Studies and Mental Ability
The Godavari river is often called 'Dakshina Ganga' mainly because
- it is the longest river of peninsular India and drains a large southern basin Correct answer.
- it is the only river that flows into the Arabian Sea from the Deccan
- it originates in the Himalayas and flows south
- it forms the boundary between two southern states for its entire course
Explanation
The Godavari is the second longest river in India and the longest in the peninsula, rising in the Western Ghats near Nashik and draining a vast basin across the Deccan before entering the Bay of Bengal. Its size and cultural importance earned it the name Dakshina Ganga.
Question 3General Studies and Mental Ability
A candidate walks 5 km north, turns right and walks 3 km, then turns right again and walks 5 km. How far and in which direction is the candidate from the starting point?
- 3 km west
- 3 km east Correct answer.
- 8 km east
- 5 km south
Explanation
Moving 5 km north then 5 km south cancels the northward displacement, leaving only the 3 km eastward leg. Facing north, a right turn points east, so the final position is 3 km east of the start.

The Fundamental Duties were added to the Constitution of India by which amendment?
- 73rd Amendment
- 52nd Amendment
- 42nd Amendment Correct answer.
- 44th Amendment
Explanation
The 42nd Amendment Act, 1976 inserted Part IVA (Article 51A) listing Fundamental Duties, on the recommendation of the Swaran Singh Committee. A later amendment added more duties, but the original insertion was by the 42nd.
Question 7General Studies and Mental Ability
Which of the following is a Kharif crop in the Indian cropping pattern?
- Barley
- Mustard
- Wheat
- Cotton Correct answer.
Explanation
Kharif crops are sown with the onset of the monsoon and harvested in autumn; cotton, rice, maize and jowar are typical examples. Wheat, mustard and barley are Rabi crops grown in the winter season.
Question 8General Studies and Mental Ability
The 'Green Revolution' in India during the late 1960s is most closely associated with which crop and programme?
- Rice in eastern India under the Intensive Agriculture District Programme
- Sugarcane in the Deccan under cooperative mills
- Jute in Bengal under the Grow More Food campaign
- Wheat in north-western India using high-yielding varieties Correct answer.
Explanation
The Green Revolution centred on semi-dwarf high-yielding wheat varieties introduced in Punjab, Haryana and western Uttar Pradesh, supported by irrigation and fertiliser use. It sharply raised wheat output and reduced dependence on imports.
Question 9General Studies and Mental Ability
Which of the following is the primary source of energy for the Earth's atmospheric circulation?
- Tidal forces from the Moon
- Radioactive decay within the crust
- Geothermal heat from the Earth's interior
- Unequal heating of the Earth's surface by the Sun Correct answer.
Explanation
The atmosphere is driven mainly by differential solar heating, which creates pressure gradients and hence winds. Latent heat released in convection further energises weather systems, but the ultimate source is the Sun.
Question 10General Studies and Mental Ability
A sum of money doubles itself in 8 years at simple interest. In how many years will it become four times itself at the same rate?
- 16 years
- 32 years
- 24 years Correct answer.
- 12 years
Explanation
Doubling in 8 years at simple interest means the interest equals the principal in 8 years, so the rate is 100/8 = 12.5% per annum. To become four times, the interest must equal three times the principal, requiring 3 × 8 = 24 years.
Question 11General Studies and Mental Ability
The average age of 10 students in a class is 15 years. When the teacher's age is included, the average rises by 2 years. What is the teacher's age?
- 41 years
- 37 years Correct answer.
- 35 years
- 39 years
Explanation
The total age of the students is 10 × 15 = 150 years. With the teacher, the average of 11 persons is 17 years, giving a total of 187 years, so the teacher's age is 187 − 150 = 37 years.
Question 12General Studies and Mental Ability
If A : B = 3 : 4 and B : C = 8 : 9, then A : C equals
- 3 : 4
- 2 : 3 Correct answer.
- 8 : 9
- 1 : 2
Explanation
Make the B terms equal: A : B = 6 : 8 and B : C = 8 : 9, so A : B : C = 6 : 8 : 9. Therefore A : C = 6 : 9 = 2 : 3.
Question 13General Studies and Mental Ability
A train 150 m long crosses a pole in 10 seconds. What is its speed in km/h?
- 36 km/h
- 45 km/h
- 54 km/h Correct answer.
- 60 km/h
Explanation
Crossing a pole takes the train past a single point, so speed = length ÷ time = 150/10 = 15 m/s. Converting to km/h by multiplying by 18/5 gives 54 km/h.
Question 14General Studies and Mental Ability
Which of the following pairs of Indian states share a boundary with the maximum number of other states?
- Madhya Pradesh and Andhra Pradesh
- Uttar Pradesh and Assam Correct answer.
- Maharashtra and Bihar
- Rajasthan and Odisha

- 1st Amendment; 'republic' was added
- 44th Amendment; 'federal' was added
- 52nd Amendment; 'integrity' was added
- 42nd Amendment; 'socialist' and 'secular' were added Correct answer.
Explanation
The 42nd Amendment Act, 1976 added the words 'socialist' and 'secular' to the Preamble, and also changed 'sovereign democratic republic' to 'sovereign socialist secular democratic republic'. The Preamble has been amended only once.
Question 16General Studies and Mental Ability
Which of the following is the correct sequence of the layers of the atmosphere from the Earth's surface upward?
- Mesosphere, troposphere, stratosphere, thermosphere
- Troposphere, mesosphere, stratosphere, thermosphere
- Troposphere, stratosphere, mesosphere, thermosphere Correct answer.
- Stratosphere, troposphere, thermosphere, mesosphere
Explanation
The atmosphere is layered by temperature behaviour: the troposphere (weather zone) lies lowest, followed by the stratosphere with the ozone layer, then the mesosphere where meteors burn, and finally the thermosphere.
Question 17General Studies and Mental Ability
In a class of 60 students, 35 play cricket, 30 play hockey and 10 play neither. How many play both games?
- 15 Correct answer.
- 10
- 20

Question 18General Studies and Mental Ability
The Battle of Plassey (1757) was significant because it
- established British political control over Bengal after the defeat of Siraj-ud-Daulah Correct answer.
- ended the Anglo-Maratha wars permanently
- transferred the capital of British India from Calcutta to Delhi
- marked the final defeat of Tipu Sultan
Explanation
Robert Clive's victory over Nawab Siraj-ud-Daulah at Plassey gave the East India Company effective control of Bengal's revenues and politics. This is widely treated as the beginning of British territorial power in India.

- 2, 3, 1, 4
- 1, 2, 3, 4
- 2, 1, 3, 4 Correct answer.
- 3, 1, 2, 4
Explanation
The Partition of Bengal occurred in 1905, the Jallianwala Bagh massacre in 1919, the Dandi March in 1930 and the Quit India Movement in 1942. The correct sequence is therefore 2, 1, 3, 4.
Question 20General Studies and Mental Ability
Which of the following is a constitutional body in India?
- Central Bureau of Investigation
- Comptroller and Auditor General Correct answer.
- National Human Rights Commission
- NITI Aayog
Explanation
The CAG is established by Article 148 of the Constitution and is thus a constitutional body. NITI Aayog, the CBI and the NHRC are created by executive resolution or statute, not directly by the Constitution.
Question 21General Studies and Mental Ability
A man spends 70% of his monthly income and saves the rest. If his savings are ₹4,500, what is his monthly income?
- ₹18,000
- ₹16,500
- ₹15,000 Correct answer.
- ₹13,500
Explanation
Savings equal 30% of income, so 0.30 × income = 4,500, giving income = 4,500 ÷ 0.30 = ₹15,000.
Question 22General Studies and Mental Ability
Which of the following statements about the Indian monsoon is correct?
- The north-east monsoon brings most rain to the Konkan coast
- The south-west monsoon reaches Kerala first around early June Correct answer.
- The monsoon retreats from Kerala before it retreats from Rajasthan
- The south-west monsoon first reaches Punjab in April
Explanation
The south-west monsoon normally sets in over Kerala around 1 June and then advances north-westwards across the country. Withdrawal begins in north-west India in September before retreating southwards.
Question 23General Studies and Mental Ability
Find the next term in the series: 2, 6, 12, 20, 30, ?
- 36
- 40
- 42 Correct answer.
- 48
Explanation
The differences between successive terms are 4, 6, 8, 10, increasing by 2 each time. The next difference is 12, so the next term is 30 + 12 = 42.
Question 24General Studies and Mental Ability
Which of the following best explains why the Deccan Plateau has black soil in parts of Maharashtra and Madhya Pradesh?
- Deposition of alluvium by the Godavari river
- Decay of mangrove vegetation along the coast
- Wind-blown loess from the Thar Desert
- Weathering of basaltic lava of the Deccan Traps Correct answer.
Explanation
Black cotton soil, or regur, forms from the weathering of basaltic lava that spread across the Deccan during the Cretaceous-Palaeogene volcanic episodes. Its clay-rich, moisture-retentive nature makes it valuable for cotton.
Question 25General Studies and Mental Ability
The Speaker of the Lok Sabha is elected by
- the members of the Lok Sabha Correct answer.
- the Council of Ministers
- the members of both Houses of Parliament
- the President of India
Explanation
Article 93 provides that the Speaker and Deputy Speaker are chosen by the House of the People from among its own members. The President does not appoint the Speaker.
Question 26General Studies and Mental Ability
Under the Indian Constitution, the power to issue writs for the enforcement of Fundamental Rights is vested in the Supreme Court under which article?
- Article 141
- Article 32 Correct answer.
- Article 136
- Article 226
Explanation
Article 32 empowers the Supreme Court to issue writs such as habeas corpus, mandamus, prohibition, quo warranto and certiorari for enforcing Fundamental Rights, and Dr. Ambedkar called it the heart and soul of the Constitution. Article 226 gives a similar but wider power to High Courts.
Question 27General Studies and Mental Ability
A shopkeeper marks an article 40% above cost price and then allows a discount of 25% on the marked price. What is his profit percentage?
- 12.5%
- 5% Correct answer.
- 10%
- 15%
Explanation
Let cost price be 100; marked price becomes 140 and selling price after 25% discount is 140 × 0.75 = 105, so profit is 5 on 100, i.e. 5%. The successive change rule (40 − 25 − 40×25/100) also gives 5%.
Question 28General Studies and Mental Ability
Which soil type covers most of the northern plains of India and is formed from alluvial deposits brought by the Himalayan rivers?
- Laterite soil
- Black soil
- Red soil
- Alluvial soil Correct answer.
Explanation
Alluvial soil is deposited by the Indus, Ganga and Brahmaputra systems and dominates the northern plains and coastal deltas; it is rich in potash and lime and supports intensive agriculture. Black soil is lava-derived and typical of the Deccan, laterite forms in heavy rainfall zones, and red soil develops on crystalline rocks.
Question 29General Studies and Mental Ability
The Indian National Congress was founded in 1885 during the tenure of which Viceroy of India?
- Lord Canning
- Lord Curzon
- Lord Ripon
- Lord Dufferin Correct answer.
Explanation
The Congress was founded at Bombay in December 1885 while Lord Dufferin was Viceroy (1884–1888). Ripon had earlier encouraged local self-government and is associated with the Ilbert Bill, while Curzon came later and ordered the partition of Bengal in 1905.
Question 30General Studies and Mental Ability
Find the odd one out in the series: 121, 144, 169, 182, 196.
- 182 Correct answer.
- 121
- 196
- 169
Explanation
121, 144, 169 and 196 are perfect squares of 11, 12, 13 and 14 respectively. The number 182 is not a perfect square and breaks the pattern, so it is the odd term.
Question 31General Studies and Mental Ability
Which of the following is the largest gland in the human body and secretes bile?
- Salivary gland
- Thyroid
- Liver Correct answer.
- Pancreas
Explanation
The liver is the largest gland in the human body and also the largest internal organ; it produces bile, which is stored in the gall bladder and aids fat digestion. The pancreas is a mixed gland but far smaller, and the thyroid and salivary glands are much smaller still.
Question 32General Studies and Mental Ability
Which Article of the Constitution provides for the appointment of a Finance Commission every five years?
- Article 263
- Article 315
- Article 280 Correct answer.
- Article 324
Explanation
Article 280 requires the President to constitute a Finance Commission every five years to recommend the distribution of net tax proceeds between the Union and the States and the principles governing grants-in-aid. It is a constitutional body, unlike the NITI Aayog.
Question 33General Studies and Mental Ability

- Six
- Seven
- Eight Correct answer.
- Nine
Explanation
The Tropic of Cancer (about 23°30′ N) crosses eight Indian states: Gujarat, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram. It does not pass through Odisha or Bihar, which is a common source of error.
Question 34General Studies and Mental Ability
Which of the following best describes the concept of 'doctrine of basic structure' as applied in Indian constitutional law?
- Parliament cannot amend features so fundamental that they destroy the identity of the Constitution Correct answer.
- Parliament may amend any part of the Constitution if it passes the amendment by a special majority
- The President may withhold assent to any amendment that alters federal features
- The Supreme Court may amend the Constitution to preserve its basic features
Explanation
Evolved in Kesavananda Bharati (1973), the doctrine holds that Parliament's amending power under Article 368 is wide but cannot be used to damage or destroy the basic structure, such as supremacy of the Constitution, secularism, federalism and judicial review. Amending the Constitution remains a parliamentary function, subject to that limit.
Question 35General Studies and Mental Ability
A alone can complete a work in 12 days and B alone in 18 days. They work together for 4 days, after which A leaves. In how many more days will B finish the remaining work?
- 10 days
- 8 days Correct answer.
- 6 days
- 9 days
Explanation
Combined one-day work is 1/12 + 1/18 = 5/36, so in 4 days they finish 20/36 = 5/9 of the work, leaving 4/9. B's rate is 1/18 per day, so time needed is (4/9) × 18 = 8 days.
Question 36General Studies and Mental Ability
Which of the following is the correct order of the Mughal emperors who ruled immediately after Babur?
- Humayun, Jahangir, Akbar, Aurangzeb
- Humayun, Akbar, Jahangir, Shah Jahan Correct answer.
- Akbar, Jahangir, Humayun, Shah Jahan

Explanation
After Babur (1526–1530) came Humayun, then Akbar (1556–1605), Jahangir (1605–1627) and Shah Jahan (1628–1658), followed by Aurangzeb. The Sur interregnum of Sher Shah interrupted Humayun's rule but did not displace the dynastic order.
Question 37General Studies and Mental Ability
A sum invested at compound interest compounded annually amounts to ₹6,600 in 2 years and ₹7,986 in 3 years. What is the annual rate of interest?
- 21% Correct answer.
- 10%
- 20%
- 11%
Explanation
The amount for the third year divided by the amount for the second year gives the growth factor: 7986/6600 = 1.21, so the rate is 21% per annum. Compound interest makes each year's interest proportional to the previous year's amount.
Question 38General Studies and Mental Ability
The 'Doctrine of Lapse' used by Lord Dalhousie to annex Indian states rested on which principle?
- A state could be annexed only if it failed to pay the agreed subsidy to the Company
- A state without a natural heir would lapse to the British and adoption would not be recognised Correct answer.
- A state could be annexed if its ruler was convicted of rebellion against the Company
- A state whose ruler was a minor would be administered by the Company until the ruler came of age
Explanation
Dalhousie held that dependent states without a natural heir 'lapsed' to the paramount power and refused to recognise adopted sons as heirs, using this to annex Satara, Jhansi and Nagpur. This policy deepened resentment and contributed to the discontent behind 1857.
Question 39General Studies and Mental Ability
Which of the following statements about the Rajya Sabha is correct?
- The Vice-President is its Leader of the House by virtue of office
- It is dissolved along with the Lok Sabha on the advice of the Council of Ministers
- All its members are elected by the state legislative assemblies
- It cannot be dissolved and one-third of its members retire every two years Correct answer.
Explanation
The Rajya Sabha is a permanent chamber; under Article 83 one-third of its members retire every second year and each member serves six years, so the House is never dissolved. The Vice-President is its ex-officio Chairman, while the Leader of the House is a nominated member of the ruling party.
Question 40General Studies and Mental Ability
Which of the following is the chief cause of the occurrence of the 'October heat' in northern India?
- Retreat of the monsoon accompanied by high temperature and high humidity Correct answer.
- Sudden intrusion of maritime air from the Bay of Bengal
- Onset of the south-west monsoon with heavy cloud cover
- Western disturbances bringing cold winds from Central Asia
Explanation
During the retreat of the monsoon in October, the land is still hot while moist air remains, producing oppressive heat with high humidity, often called the 'October heat'. The monsoon trough weakens and clear skies raise daytime temperatures.
Question 41General Studies and Mental Ability
A person walks 5 km north, turns right and walks 3 km, turns right and walks 5 km. How far and in which direction is he from the starting point?
- 3 km east Correct answer.
- 5 km north
- 3 km west
- 8 km east
Explanation
Starting north 5 km and then turning right (east) 3 km, a further right turn faces south and 5 km cancels the northward displacement. The net displacement is therefore 3 km due east of the start.
Question 42General Studies and Mental Ability
Which of the following gases is chiefly responsible for the depletion of the ozone layer over Antarctica?
- Chlorofluorocarbons Correct answer.
- Sulphur dioxide
- Carbon dioxide
- Methane
Explanation
Chlorofluorocarbons release chlorine atoms in the stratosphere, and each chlorine atom can destroy thousands of ozone molecules, especially on polar stratospheric clouds in Antarctic spring. The Montreal Protocol was framed to phase out such ozone-depleting substances.
Question 43General Studies and Mental Ability
The Reserve Bank of India raises the repo rate. Which of the following is the most likely immediate consequence?
- Inflation accelerates because money supply expands
- Cost of borrowing rises and credit growth tends to slow Correct answer.
- Commercial banks reduce their lending rates immediately
- Foreign institutional investment is banned by the RBI
Explanation
Repo is the rate at which the RBI lends short-term funds to banks; raising it makes borrowing costlier, so banks transmit higher lending rates and credit expansion moderates, helping contain demand-driven inflation. The RBI does not ban foreign investment through the repo rate.
Question 44General Studies and Mental Ability
Which of the following is the correct sequence of the stages of the Indian budgeting process?
- Appropriation bill, preparation of estimates, finance bill, discussion on demands
- Discussion on demands, preparation of estimates, appropriation bill, finance bill
- Preparation of estimates, presentation in Parliament, discussion and voting on demands, appropriation and finance bills Correct answer.
- Presentation in Parliament, appropriation bill, preparation of estimates, discussion on demands
Explanation
The Budget is first prepared by the Finance Ministry, then presented to Parliament, followed by general discussion and voting on demands for grants, and finally the Appropriation Bill and Finance Bill are passed. The Finance Bill gives effect to taxation proposals, while the Appropriation Bill authorises expenditure from the Consolidated Fund.
Question 45General Studies and Mental Ability
If in a certain code MANGO is written as NBOHP, which rule is being applied and what is the code for GRAPE?
- Each letter is shifted one step forward; HSBQF Correct answer.
- Each letter is shifted one step backward; FQZOD
- Letters are reversed; EPARG
- Each letter is shifted two steps forward; ITCRG
Explanation
Each letter of MANGO moves one place forward in the alphabet (M→N, A→B, and so on), giving NBOHP. Applying the same rule to GRAPE gives HSBQF.
Question 46General Studies and Mental Ability
The 'Green Revolution' in India was enabled by a combination of which of the following factors?
- Mechanised fishing and cold-chain development
- Extension of shifting cultivation and organic manure
- Expansion of plantation crops and cheap labour
- High-yielding varieties, assured irrigation and chemical fertilisers Correct answer.
Explanation
The Green Revolution rested on semi-dwarf high-yielding wheat and rice varieties, assured irrigation, fertilisers, pesticides and institutional credit, along with price support. Its core gain was in wheat in Punjab, Haryana and western Uttar Pradesh.
Question 47General Studies and Mental Ability
Which of the following statements about the Fundamental Rights in India is correct?
- They are mostly available against the State, and some are available against private individuals as well Correct answer.
- They are available only against the Union Government and not against State Governments
- They are available only to citizens and never to foreigners
- They can be suspended by Parliament at any time by ordinary law
Explanation
Most Fundamental Rights under Articles 14, 19 and 21 operate against the State, but Articles 17 (abolition of untouchability), 23 (traffic in human beings and forced labour) and 24 (child labour) are enforceable against private persons too. Certain rights such as those under Articles 15, 16, 19 and 29 are available only to citizens.
Question 48General Studies and Mental Ability
A trader mixes two varieties of rice costing ₹40 per kg and ₹60 per kg in some ratio and sells the mixture at ₹60 per kg, thereby gaining 20%. In what ratio were the two varieties mixed?
- 1 : 1 Correct answer.
- 1 : 2
- 3 : 2
- 2 : 1
Explanation
A 20% gain on a selling price of ₹60 means the cost of the mixture is 60/1.2 = ₹50 per kg. By the rule of alligation, the ratio of the ₹40 and ₹60 varieties is (60 − 50) : (50 − 40) = 10 : 10 = 1 : 1.
Question 49General Studies and Mental Ability
Which of the following best explains why the western coast of India receives much heavier rainfall than the interior of the Deccan during the south-west monsoon?
- The Arabian Sea is cooler than the Bay of Bengal during the monsoon
- The interior lies closer to the Equator and therefore receives less moisture
- The Western Ghats force moist winds to rise, causing orographic rainfall on the windward side Correct answer.
- The interior is shielded by the Eastern Ghats from all monsoon winds
Explanation
Moist south-west monsoon winds strike the Western Ghats and are forced to ascend, cooling and condensing to give heavy orographic rain on the windward western slopes. The leeward interior lies in a rain-shadow and receives far less rain.
Question 50General Studies and Mental Ability
Which of the following statements about the Governor of an Indian state is correct?
- The Governor is appointed for a fixed term of five years and cannot be removed earlier
- The Governor must be a resident of the state to which he or she is appointed
- The Governor is elected by the state legislative assembly by a special majority
- The Governor is appointed by the President and holds office during the pleasure of the President Correct answer.
Explanation
Under Articles 155 and 156, the Governor is appointed by the President and holds office during the pleasure of the President, though the normal term is five years. The Constitution only requires that the Governor should not be a member of either House or hold any office of profit; residence in the state is not required.
