  1. Amritsar Correct answer.
  2. Lahore
  3. Delhi
  4. Kanpur

  2. Lord William Bentinck
  3. Lord Dalhousie Correct answer.
  4. Lord Curzon

Explanation

Lord Dalhousie, Governor-General from 1848 to 1856, applied the Doctrine of Lapse to annex states such as Satara, Jhansi and Nagpur when rulers died without a natural heir. The policy was one of the major grievances behind the revolt of 1857. Bentinck is known for social reforms, Ripon for local self-government, and Curzon for the partition of Bengal.

Question 35General Intelligence & Reasoning

In a coded language, DELHI is written as EFMIJ. Using the same rule, how would POLICE be written?

  1. QPNJDF
  2. QPMJDF Correct answer.
  3. QPMJDE
  4. OQNJDF

Explanation

The rule shifts each letter forward by one position in the alphabet: D→E, E→F, L→M, H→I, I→J. Applying the same +1 shift to POLICE gives P→Q, O→P, L→M, I→J, C→D, E→F, producing QPMJDF. Each letter is handled independently, so the pattern stays consistent across the whole word.

Question 36General Intelligence & Reasoning

If 'rose' is called 'lily', 'lily' is called 'lotus', and 'lotus' is called 'marigold', then which flower is traditionally offered in temples according to this code language?

  1. lotus
  2. rose
  3. marigold Correct answer.
  4. lily

Explanation

In the code, the word 'lotus' is renamed 'marigold'. Since the question asks for the flower actually offered in temples (the real lotus), you must answer using the code name for lotus, which is marigold. The trick is to translate the real object into its coded label, not to answer with the coded word itself.

Question 37General Intelligence & Reasoning

Pointing to a photograph, a Head Constable says, 'She is the daughter of my grandfather's only son.' How is the girl in the photograph related to him?

  1. Daughter
  2. Sister Correct answer.
  3. Cousin
  4. Niece

Explanation

The grandfather's only son must be the speaker's own father, since a single son leaves no uncle. The daughter of the speaker's father is therefore the speaker's sister. 'Only son' is the key phrase that rules out cousins or nieces.

Question 38General Intelligence & Reasoning

A is the brother of B. B is the sister of C. C is the father of D. How is A related to D?

  1. Father
  2. Brother
  3. Uncle Correct answer.
  4. Grandfather

Explanation

A and B are siblings, and B is the sister of C, so A, B and C are all siblings of the same generation. Since C is D's father, A is the brother of D's father, which makes A D's uncle. The gender of A is given as male through 'brother', confirming uncle rather than aunt.

Question 39General Intelligence & Reasoning

Complete the series: 3, 7, 15, 31, 63, ?

  1. 129
  2. 127 Correct answer.
  3. 126
  4. 125

Explanation

Each term equals the previous term multiplied by 2 and then increased by 1: 3×2+1=7, 7×2+1=15, and so on. Applying the rule to 63 gives 63×2+1=127. Equivalently, each term is one less than a power of two (4−1, 8−1, 16−1...), and the next is 128−1=127.

Question 40General Intelligence & Reasoning

Find the odd one out: 121, 144, 169, 180, 196

  1. 180 Correct answer.
  2. 121
  3. 196
  4. 169

Explanation

121, 144, 169 and 196 are perfect squares (11², 12², 13², 14²). The number 180 is not a perfect square, so it breaks the pattern. Checking squares of consecutive integers is the quickest way to spot the intruder.

Question 41General Intelligence & Reasoning

If South-East becomes North, North-East becomes West, and so on, what does South become?

  1. East
  2. North-West
  3. South-West
  4. North-East Correct answer.

Explanation

The transformation rotates every direction by 135 degrees anticlockwise: South-East→North, North-East→West. Applying the same 135-degree anticlockwise turn to South gives North-East. A consistent rotation must map all directions the same way, so the answer follows from the two given examples.

Question 42General Intelligence & Reasoning

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

  1. 5 km north
  2. 8 km east
  3. 3 km west
  4. 3 km east Correct answer.

Explanation

Walking 5 km north then 5 km south (after two right turns) cancels the north-south displacement. The remaining movement is the 3 km eastward leg, so he ends 3 km east of the start. Drawing the path makes the cancellation of the two 5 km legs obvious.

Question 43General Intelligence & Reasoning

Six clerks A, B, C, D, E and F sit in a row facing north. A is to the immediate left of B. C is at the extreme right end. D is between A and E. Who sits at the extreme left end?

  1. A
  2. F
  3. D
  4. E Correct answer.

Explanation

Since D is between A and E and A is immediately left of B, the block reads E–D–A–B in that order. With C fixed at the far right, the only arrangement is E, D, A, B, F, C, placing E at the extreme left. Working from the fixed end (C) inward resolves the row quickly.

Question 44General Intelligence & Reasoning

Five files are stacked one above another. P is above Q but below R. S is above R. T is below Q. Which file is at the bottom of the stack?

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

Explanation

S is above R, R is above P, P is above Q, and Q is above T, giving the order S, R, P, Q, T from top to bottom. Therefore T occupies the lowest position. Chaining the 'above' relations into a single vertical order is the reliable method here.

Question 45General Intelligence & Reasoning

In a certain code, if 'MINISTER' is written as 'NJOJTUFS', which letter-shift rule is being used?

  1. Each letter moves one step backward
  2. Each letter moves two steps forward
  3. Each letter moves one step forward Correct answer.
  4. Each letter moves two steps backward

Explanation

Comparing M→N, I→J, N→O and so on shows every letter advancing by exactly one alphabet position. The whole word follows a uniform +1 shift, so the rule is one step forward. Checking the first two letters is enough to identify the shift.

Question 46General Intelligence & Reasoning

Statements: All constables are policemen. Some policemen are drivers. Conclusions: (I) Some constables are drivers. (II) Some drivers are policemen. Which conclusion follows?

  1. Neither I nor II follows
  2. Only I follows
  3. Both I and II follow
  4. Only II follows Correct answer.

Explanation

Conclusion II is the valid conversion of 'some policemen are drivers', since 'some A are B' implies 'some B are A'. Conclusion I is not guaranteed because the drivers who are policemen may lie entirely outside the constable group. Only II is logically certain.

Question 47General Intelligence & Reasoning

Statements: No clerk is a peon. All peons are guards. Conclusions: (I) No clerk is a guard. (II) Some guards are peons. Which conclusion follows?

  1. Only I follows
  2. Only II follows Correct answer.
  3. Neither I nor II follows
  4. Both I and II follow

Explanation

Since all peons are guards, at least some guards are peons, making II valid. Conclusion I is too strong: clerks are excluded from peons, but clerks could still be guards who are not peons. Hence only II follows.

Question 48General Intelligence & Reasoning

If in a certain year 15 August falls on a Wednesday, what day of the week will 2 October of the same year be?

  1. Wednesday
  2. Monday
  3. Thursday
  4. Tuesday Correct answer.

Explanation

From 15 August to 2 October there are 16 days left in August plus 2 days in October, totalling 48 days. Dividing 48 by 7 leaves a remainder of 6, so the day advances six places from Wednesday, landing on Tuesday. Counting the odd days correctly is the key step.

Question 49General Intelligence & Reasoning

A clock shows 3:30. What is the angle between the hour hand and the minute hand?

  1. 90 degrees
  2. 105 degrees
  3. 75 degrees Correct answer.
  4. 60 degrees

Explanation

At 3:30 the minute hand points at 6 (180 degrees) and the hour hand has moved halfway between 3 and 4, sitting at 105 degrees from 12. The difference is 180 − 105 = 75 degrees. The formula |30H − 5.5M| gives |90 − 165| = 75, confirming the result.

Question 50General Intelligence & Reasoning

Which number should replace the question mark? 8 : 512 :: 6 : ?

  1. 128
  2. 216 Correct answer.
  3. 64
  4. 36

Explanation

The relation is cube of the first number: 8³ = 512. Applying the same rule, 6³ = 216. The colon pattern requires the second term to be the cube of the first, not its square or double.
