Question 5General 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 of itself at the same rate?

  1. 16 years
  2. 24 years Correct answer.
  3. 20 years
  4. 32 years

Explanation

Doubling in 8 years means the simple interest equals the principal in 8 years, so the rate is 12.5% per annum. To become four times, the interest must equal three times the principal, which takes 3 × 8 = 24 years.

Question 6General Studies and Mental Ability

If the ratio of the ages of A and B is 3:4 and the sum of their ages is 42 years, what is B's age?

  1. 28 years
  2. 21 years
  3. 24 years Correct answer.
  4. 18 years

Explanation

Let the ages be 3x and 4x, so 7x = 42, giving x = 6. B's age is 4 × 6 = 24 years.

Question 7General Studies and Mental Ability

A train 150 m long crosses a pole in 15 seconds. What is the speed of the train?

  1. 54 km/h
  2. 40 km/h
  3. 36 km/h Correct answer.
  4. 45 km/h

Explanation

Crossing a pole means the train covers its own length, so speed = 150/15 = 10 m/s. Converting to km/h by multiplying by 18/5 gives 36 km/h.

Question 8General Studies and Mental Ability

The average of five numbers is 27. If one number is removed, the average of the remaining four becomes 25. What is the removed number?

  1. 30
  2. 35 Correct answer.
  3. 25
  4. 40

Explanation

The sum of five numbers is 5 × 27 = 135, and the sum of the remaining four is 4 × 25 = 100. The removed number is therefore 135 − 100 = 35.

  1. Mesosphere
  2. Troposphere
  3. Thermosphere
  4. Stratosphere Correct answer.

  1. MKPO
  2. MJNO
  3. MJPN
  4. MJPO Correct answer.

  1. R
  2. Q
  3. P Correct answer.
  4. S

Explanation

With T at one end and S between R and T, the block T-S-R must occupy one end. Q immediately right of P means the pair P-Q sits together. Arranging these gives P-Q-R-S-T, placing P at the other end.

Question 22General Studies and Mental Ability

A man walks 5 km north, turns right and walks 3 km, then turns right and walks 5 km. How far is he from his starting point?

  1. 3 km Correct answer.
  2. 5 km
  3. 8 km
  4. 13 km

  1. A restaurant meal
  2. A national defence system Correct answer.
  3. A private car
  4. A cinema ticket

  1. Minerva Mills v. Union of India

  4. Bengal and Bihar

The Ryotwari system was introduced by Thomas Munro and Alexander Read in the Madras Presidency and extended to the Bombay Presidency. Under this system, revenue was settled directly with the individual cultivator (ryot) rather than through zamindars. The Permanent Settlement covered Bengal and Bihar, while the Mahalwari system covered parts of the North-West Provinces.

Question 28General Studies and Mental Ability

Consider the following statements about the Indian monsoon: 1. The onset of the southwest monsoon over Kerala normally occurs around 1 June. 2.

Which of the statements given above are correct?

  1. 2 and 3 only
  2. 1 and 3 only Correct answer.
  3. 1 and 2 only
  4. 1, 2 and 3

Explanation

The southwest monsoon normally sets in over Kerala around 1 June, and its withdrawal begins from northwest India in September. The Tamil Nadu coast is a rain-shadow area during the southwest monsoon and receives most of its rainfall from the retreating northeast monsoon (October–December). Hence statement 2 is incorrect.

Question 29General Studies and Mental Ability

In a class of 40 students, 25 play cricket, 20 play football, and 10 play both. How many students play neither cricket nor football?

  1. 10
  2. 5 Correct answer.
  3. 15
  4. 20

Explanation

By the principle of inclusion–exclusion, the number playing at least one game is 25 + 20 − 10 = 35. Therefore, the number playing neither is 40 − 35 = 5.

Explanation

The Champaran Satyagraha took place in 1917, the Jallianwala Bagh massacre in 1919, the Non-Cooperation Movement was launched in 1920, and the Dandi March occurred in 1930. Thus the correct order is 1, 2, 3, 4.

Explanation

The atmosphere is divided into layers based on temperature variations: the troposphere (0–12 km), stratosphere (12–50 km), mesosphere (50–80 km), and thermosphere (80 km and above). The ozone layer lies within the stratosphere, and the mesosphere is where most meteors burn up.

The 'Doctrine of Lapse' was used by which Governor-General to annex Indian princely states?

  1. Lord Hastings
  2. Lord Cornwallis
  3. Lord Wellesley
  4. Lord Dalhousie Correct answer.

Explanation

The Doctrine of Lapse was an annexation policy applied by Lord Dalhousie (Governor-General from 1848 to 1856). Under this doctrine, any princely state without a natural heir would be annexed by the British East India Company. States like Satara, Jhansi, and Nagpur were annexed under this policy.

Question 35General Studies and Mental Ability

Which of the following is an example of a 'demand-pull' factor in inflation?

  1. A poor harvest leading to food shortages
  2. An increase in the cost of raw materials due to a strike
  3. A sharp rise in the price of imported crude oil
  4. A rapid increase in government spending during a war Correct answer.

Explanation

Demand-pull inflation occurs when aggregate demand outpaces aggregate supply, often due to increased government spending, investment, or consumption. A rise in imported oil prices, poor harvests, and higher raw material costs are supply-side (cost-push) factors. Therefore, increased government spending is the demand-pull example.

Question 36General Studies and Mental Ability

If the compound interest on a sum of money for 2 years at 10% per annum is ₹210, what is the simple interest on the same sum at the same rate and for the same period?

  1. ₹200 Correct answer.
  2. ₹220
  3. ₹210
  4. ₹190

Explanation

For 2 years, the difference between compound interest and simple interest is the interest on the first year's interest. Let the principal be P. Compound interest = P[(1+10/100)^2 - 1] = P(1.21 - 1) = 0.21P. Given 0.21P = 210, P = 1000. Simple interest = P × 10 × 2 / 100 = 1000 × 20 / 100 = ₹200.

Question 37General Studies and Mental Ability

Which of the following pairs of Indian dance forms and their states of origin is correctly matched?

  1. Odissi – West Bengal
  2. Sattriya – Assam Correct answer.
  3. Mohiniyattam – Karnataka
  4. Kuchipudi – Tamil Nadu

Explanation

Sattriya is a classical dance form that originated in the Vaishnava monasteries (sattras) of Assam. Mohiniyattam belongs to Kerala, Kuchipudi to Andhra Pradesh, and Odissi to Odisha. Hence only the first pair is correctly matched.

Question 38General Studies and Mental Ability

The 'Green House Effect' refers to which of the following processes?

  1. Trapping of infrared radiation by atmospheric gases, warming the Earth's surface Correct answer.
  2. Reflection of solar radiation by the ozone layer
  3. Absorption of ultraviolet radiation by the stratosphere
  4. Cooling of the Earth's surface due to increased cloud cover

Explanation

The greenhouse effect is the process by which certain gases in the atmosphere, such as carbon dioxide, methane, and water vapour, absorb and re-emit infrared radiation, thereby warming the Earth's surface. This natural process is essential for maintaining the planet's temperature. Reflection by the ozone layer and absorption of UV radiation are different phenomena.

Question 39General Studies and Mental Ability

Consider the following statements about the Election Commission of India (ECI): 1. The Chief Election Commissioner can be removed only in the same manner as a judge of the Supreme Court. 2. The ECI is a constitutional body established under Article 324. 3. The ECI conducts elections to the Panchayats and Municipalities. Which of the statements given above are correct?

  1. 1 and 2 only Correct answer.
  2. 1, 2 and 3
  3. 1 and 3 only
  4. 2 and 3 only

Explanation

The Chief Election Commissioner can be removed only by impeachment, similar to a Supreme Court judge, and the ECI is established under Article 324. However, elections to Panchayats and Municipalities are conducted by the State Election Commission, not the ECI. Hence statements 1 and 2 are correct, but 3 is not.

Question 40General Studies and Mental Ability

A sum of money invested at compound interest amounts to ₹1,210 in 2 years and to ₹1,331 in 3 years. What is the rate of interest per annum?

  1. 11%
  2. 12%
  3. 9%
  4. 10% Correct answer.

Explanation

The amount grows from ₹1,210 to ₹1,331 in one year, so the interest for the third year is ₹121. The rate is (121/1210) × 100 = 10% per annum. Compound interest means the interest is calculated on the amount at the beginning of each year.
