Question 1Reasoning Ability

In a coded language, the word 'BANK' is written as 'CBOL'. Following the same rule, how would 'POINT' be written?

  1. QNJOU
  2. QPIOU
  3. QPJOU Correct answer.
  4. QPOJU

Explanation

Each letter of BANK moves one step forward in the alphabet: B→C, A→B, N→O, K→L, giving CBOL. Applying the same +1 shift to POINT gives Q, P, J, O, U, i.e. QPJOU.

Question 2Reasoning Ability

Pointing to a photograph, Ravi said, 'She is the daughter of the only son of my mother.' How is the girl in the photograph related to Ravi?

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

Explanation

The only son of Ravi's mother is Ravi himself (assuming Ravi is that son), so the daughter of that son is Ravi's own daughter. However, if the speaker is male and the phrase refers to himself, the girl is his daughter; the standard reading of such puzzles treats 'only son of my mother' as the speaker's brother only when the speaker is female. For a male speaker, the girl is his daughter.

Question 3Reasoning Ability

Six friends A, B, C, D, E and F sit in a row facing north. C is immediately to the right of A. B is at one of the extreme ends. F sits second to the left of D. E sits between B and C. If B is at the leftmost end, who sits at the rightmost end?

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

Explanation

With B at position 1, E must be adjacent to B and C, so E is at 2 and C at 3. Since C is immediately right of A, A is at 2, which conflicts, so the arrangement must place A at 1... Rechecking: B at 1, E between B and C means order B-E-C, so E=2, C=3, A=2 is impossible; hence B is at the rightmost end in the consistent reading, placing D at the far left. The only arrangement satisfying all clues ends with D at the right.

Question 4Reasoning Ability

Statements: All pens are books. Some books are red. Conclusions: I. Some pens are red. II. Some red are books. Which conclusion logically follows?

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

Explanation

'Some books are red' converts to 'Some red are books', so conclusion II definitely follows. Conclusion I is not guaranteed because the red books may be entirely outside the pen subset.

Question 5Reasoning Ability

Find the next number in the series: 3, 8, 18, 38, 78, ?

  1. 158 Correct answer.
  2. 156
  3. 148
  4. 168

Explanation

Each term equals the previous term multiplied by 2 and then increased by 2: 3×2+2=8, 8×2+2=18, 18×2+2=38, 38×2+2=78. Applying the rule again gives 78×2+2=158.

Question 6Reasoning Ability

If in a certain code 'DELHI' is written as 'CDKGH', which rule is being applied?

  1. Vowels are replaced by the previous consonant
  2. Letters are reversed and then shifted
  3. Each letter is shifted one place backward Correct answer.
  4. Each letter is shifted one place forward

Explanation

Comparing D→C, E→D, L→K, H→G, I→H shows every letter moved one position backward in the alphabet. The rule is therefore a uniform −1 shift.

Question 7Reasoning Ability

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

Explanation

A, B and C are siblings, and C is D's father. Therefore A, being C's brother, is D's paternal uncle.

Question 8Reasoning Ability

In a row of 40 students facing north, Ramesh is 12th from the left end. What is his position from the right end?

  1. 29th Correct answer.
  2. 30th
  3. 27th
  4. 28th

Explanation

Position from the right equals total minus position from the left plus one: 40 − 12 + 1 = 29. Ramesh is therefore 29th from the right end.

Question 9Reasoning Ability

Statements: No cat is a dog. All dogs are animals. Conclusions: I. No cat is an animal. II. Some animals are dogs. Which conclusion follows?

  1. Only II follows Correct answer.
  2. Neither follows
  3. Only I follows
  4. Both follow

Explanation

'All dogs are animals' converts to 'Some animals are dogs', so conclusion II follows. Conclusion I is invalid because cats may still be animals even though no cat is a dog.

Question 10Reasoning Ability

Five people P, Q, R, S and T are sitting around a circular table facing the centre. Q is to the immediate right of P. R is second to the left of Q. S is not adjacent to P. Who is sitting immediately to the left of P?

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

Explanation

Fixing P and placing Q to his immediate right, R second to the left of Q falls opposite P. S cannot be beside P, so S takes the remaining seat next to R, leaving T immediately left of P.

Question 11Reasoning Ability

Which number should replace the question mark? 7 : 56 :: 9 : ?

  1. 72 Correct answer.
  2. 90
  3. 63
  4. 81

Explanation

The pattern is the number multiplied by the next integer: 7×8=56, so 9×8=72. The constant multiplier 8 links the two pairs.

Question 12Reasoning Ability

If 'CLOUD' is coded as 'DMNVE', what is the position of each letter shifted by?

  1. Alternating forward and backward
  2. One place backward
  3. Two places forward
  4. One place forward Correct answer.

Explanation

C→D, L→M, O→N, U→V, D→E shows each letter moving exactly one place forward. The shift is uniform across the word.

Question 13Reasoning 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 and in which direction?

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

Explanation

Walking 5 km north then 5 km south cancels the vertical displacement, leaving only the 3 km eastward leg. He ends 3 km east of the start.

Question 14Reasoning Ability

In a certain code, 'RAIN' is written as 'SBJO'. How would 'SNOW' be written using the same code?

  1. TOPW
  2. TOPY
  3. TOPX Correct answer.
  4. TNPX

Explanation

Each letter of RAIN is shifted one place forward: R→S, A→B, I→J, N→O. Applying the same +1 shift to SNOW gives T, O, P, X, i.e. TOPX.

Question 15Reasoning Ability

Statements: All roses are flowers. All flowers are plants. Conclusions: I. All roses are plants. II. Some plants are roses. Which is true?

  1. Only II follows
  2. Only I follows
  3. Neither follows
  4. Both I and II follow Correct answer.

Explanation

Roses are a subset of flowers, which are a subset of plants, so all roses are plants. That also guarantees some plants are roses, making both conclusions valid.

Question 16Reasoning Ability

Find the odd one out: 121, 144, 169, 200

  1. 200 Correct answer.
  2. 144
  3. 121
  4. 169

Explanation

121, 144 and 169 are perfect squares (11², 12², 13²), while 200 is not a perfect square. Hence 200 is the odd one out.

Question 17Reasoning Ability

A is taller than B but shorter than C. D is taller than C. Who is the tallest?

  1. B
  2. A
  3. C
  4. D Correct answer.

Explanation

The chain is D > C > A > B, since A is shorter than C and D is taller than C. Therefore D is the tallest of the four.

Question 18Reasoning Ability

In a family, X is the son of Y. Y is the daughter of Z. W is the brother of Z. How is W related to X?

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

Explanation

Y is X's mother and Z is Y's parent, so Z is X's grandparent. W, being Z's brother, is a sibling of X's grandparent, which makes him X's great-uncle in strict terms but is conventionally shown as uncle-level in these puzzles.

Question 19Reasoning Ability

If 5th March of a year is a Wednesday, what day is 5th April of the same year (non-leap year)?

  1. Saturday Correct answer.
  2. Friday
  3. Thursday
  4. Sunday

Explanation

March has 31 days, so the day advances by 31 mod 7 = 3 days from 5 March to 5 April. Three days after Wednesday is Saturday.

Question 20Reasoning Ability

The hands of a clock are at 3:00. What is the angle between the hour hand and the minute hand?

  1. 120 degrees
  2. 90 degrees Correct answer.
  3. 45 degrees
  4. 60 degrees

Explanation

At 3:00 the minute hand points at 12 and the hour hand at 3. Each hour mark is 30 degrees apart, so three marks give 3 × 30 = 90 degrees.

Question 21Reasoning Ability

Six boxes are stacked one above another. Box P is above Q. Box R is above P. Box S is below Q. Box T is between P and Q. Which box is at the bottom?

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

Explanation

The vertical order from top is R, P, T, Q, S, since R is above P, T lies between P and Q, and S is below Q. Hence S occupies the lowest position.

Question 22Reasoning Ability

Find the missing term: 2, 6, 12, 20, 30, ?

  1. 40
  2. 42 Correct answer.
  3. 44
  4. 36

Explanation

The differences are 4, 6, 8, 10, increasing by two each time. The next difference is 12, so 30 + 12 = 42.

Question 23Reasoning Ability

Statement: Some doctors are lawyers. All lawyers are graduates. Conclusion: Some doctors are graduates. Does the conclusion follow?

  1. Cannot be determined under any condition
  2. Yes, it definitely follows Correct answer.
  3. No, it does not follow
  4. Follows only if all doctors are lawyers

Explanation

The doctors who are lawyers must also be graduates, because every lawyer is a graduate. Therefore at least some doctors are graduates, so the conclusion follows necessarily.

Question 24Reasoning Ability

In a code, 'MOUSE' is written as 'NPVTF'. What is the code for 'HOUSE'?

  1. IPVTF Correct answer.
  2. IPUTF
  3. IOVTF
  4. GPVTF

Explanation

Each letter is shifted one place forward: M→N, O→P, U→V, S→T, E→F. Applying the same shift to HOUSE gives I, P, V, T, F, i.e. IPVTF.

Question 25Reasoning Ability

A, B, C, D and E are five friends of different heights. B is taller than only A. C is taller than B but shorter than D. E is the tallest. Who is the shortest?

  1. A Correct answer.
  2. D
  3. B
  4. C

Explanation

B being taller than only A means A is shortest and B is second shortest. The full order is E, D, C, B, A, confirming A is the shortest.

Question 26Reasoning Ability

In a certain coding system, the word 'PLANET' is written by moving each letter two places forward in the English alphabet. Which word is produced?

  1. RNCPGV Correct answer.
  2. RNBPGV
  3. RNCPHV
  4. RMCPGV

Explanation

Each letter shifts forward by two: P→R, L→N, A→C, N→P, E→G, T→V, giving RNCPGV. The rule is applied uniformly to every position, so any deviation in even one letter makes an option invalid.

Question 27Reasoning Ability

Pointing to a photograph, Kavita says, 'He is the only son of my mother's mother.' How is the man in the photograph related to Kavita?

  1. Maternal uncle Correct answer.
  2. Cousin
  3. Brother
  4. Father

Explanation

Kavita's mother's mother is her maternal grandmother. The only son of the maternal grandmother is Kavita's mother's brother, that is, her maternal uncle. A brother would be the son of Kavita's own mother, not of her grandmother.

Question 28Reasoning Ability

In a queue of 35 candidates facing the counter, Meera is 9th from the front and Sana is 12th from the back. How many candidates stand strictly between Meera and Sana?

  1. 14 Correct answer.
  2. 12
  3. 13
  4. 15

Explanation

Sana's position from the front is 35 − 12 + 1 = 24. Candidates between positions 9 and 24 number 24 − 9 − 1 = 14. Subtracting only the two end persons, not the two named candidates, gives the correct count.

Question 29Reasoning Ability

Statements: All pens are tools. Some tools are costly. Conclusions: I. Some pens are costly. II. Some tools are pens. Which conclusion follows?

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

Explanation

Conclusion II is the valid converse of 'All pens are tools', since every pen is a tool, so some tools are pens. Conclusion I is not guaranteed because the costly tools need not include any pen.

Question 30Reasoning Ability

Six colleagues A, B, C, D, E and F sit in a straight row facing north. C sits third to the left of F. F sits at the extreme right end. Who sits at the extreme left end?

  1. D
  2. A
  3. B
  4. C Correct answer.

Explanation

With F at position 6 (extreme right), third to the left is position 3, occupied by C. The remaining people fill positions 1, 2, 4 and 5, so only C's place is fixed and no one else can be at the extreme left.

Question 31Reasoning Ability

Which number completes the analogy 13 : 169 :: 17 : ?

  1. 279
  2. 289 Correct answer.
  3. 269
  4. 299

Explanation

The pattern is the square of the first number: 13² = 169, so 17² = 289. Each option differs from the square by a multiple of ten, so checking the units digit confirms only 289 fits.

Question 32Reasoning Ability

A watch shows 4:30. What is the angle between the hour hand and the minute hand?

  1. 30 degrees
  2. 45 degrees Correct answer.
  3. 60 degrees
  4. 75 degrees

Explanation

At 4:30 the minute hand points at 6 (180°), while the hour hand has moved half past 4, giving 4.5 × 30 = 135°. The difference is 180 − 135 = 45 degrees.

Question 33Reasoning Ability

Five boxes are placed one above another. Box R is immediately above Box S. Box T is at the bottom. Box Q is immediately above Box R. Box P is at the top. Which box is in the middle position?

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

Explanation

The stack from top to bottom is P, Q, R, S, T. The middle (third) position is occupied by R, since Q is immediately above R and R is immediately above S.

Question 34Reasoning Ability

Find the missing term in the series: 3, 8, 18, 38, 78, ?

  1. 148
  2. 158 Correct answer.
  3. 138
  4. 168

Explanation

Each term is double the previous term plus 2: 3×2+2=8, 8×2+2=18, and so on, so 78×2+2=158. The differences 5, 10, 20, 40, 80 double each time, which confirms the same result.

Question 35Reasoning Ability

In a certain code, 'TABLE' is written as 'UBCMF'. How is 'CHAIR' written in the same code?

  1. DHBJS
  2. DIBJS Correct answer.
  3. DJBJS
  4. DIBIS

Explanation

Each letter moves one place forward in the alphabet: C→D, H→I, A→B, I→J, R→S, giving DIBJS. The shift is uniform at every position, so any option that changes a single letter is wrong.

Question 36Reasoning Ability

A person starts facing north, turns 90° clockwise, then 180° clockwise, then 90° anticlockwise. Which direction is the person finally facing?

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

Explanation

Net rotation is 90 + 180 − 90 = 180° clockwise from north, which points south. Tracking each turn in sequence confirms the same final facing direction.

Question 37Reasoning Ability

Statement: All engineers in the office are graduates. Some graduates in the office are women. Conclusion: Some engineers in the office are women. Does the conclusion logically follow?

  1. Yes, but only if all graduates are women
  2. No, it does not follow Correct answer.
  3. No, because no engineer is a woman
  4. Yes, it definitely follows

Explanation

The women who are graduates may all be non-engineers, so the overlap between engineers and women is not guaranteed. A conclusion follows only when it is true in every possible arrangement consistent with the statements.

Question 38Reasoning Ability

In a row of children facing south, Arjun is 7th from the left end and Bina is 9th from the right end. If they interchange positions, Arjun becomes 15th from the left. How many children are in the row?

  1. 24
  2. 22
  3. 21
  4. 23 Correct answer.

Explanation

After interchange, Arjun occupies Bina's original seat, which is 15th from the left. That same seat is 9th from the right, so total = 15 + 9 − 1 = 23. The facing direction does not affect this counting rule.

Question 39Reasoning Ability

A clock shows 7:00. If the minute hand moves to 25 minutes, through what angle does the minute hand rotate?

  1. 120 degrees
  2. 150 degrees Correct answer.
  3. 180 degrees
  4. 90 degrees

Explanation

The minute hand covers 6° per minute, so 25 minutes gives 25 × 6 = 150 degrees. The starting position at 12 does not change the angle swept, which depends only on elapsed minutes.

Question 40Reasoning Ability

Five friends P, Q, R, S and T sit around a circular table facing the centre. P is opposite R. Q is to the immediate left of P. S is to the immediate right of R. Who sits to the immediate left of R?

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

Explanation

With P opposite R and Q immediately left of P, S immediately right of R, the only remaining seat belongs to T, which falls immediately left of R. Placing all five in order confirms T is the only person who can occupy that seat.

Question 41Reasoning Ability

If in a code 'WATER' is written as 'XBUFS', what does the code 'IPXFS' decode to?

  1. HOWER
  2. HOVFR
  3. HOVER Correct answer.
  4. GOVER

Explanation

The code shifts each letter one place forward, so decoding shifts each letter one place back: I→H, P→O, X→W, F→E, S→R, giving HOVER. Applying the reverse shift at every position is essential.

Question 42Reasoning Ability

A man walks 4 km east, turns left and walks 3 km, then turns left and walks 4 km. How far and in which direction is he from the starting point?

  1. 3 km north Correct answer.
  2. 4 km west
  3. 5 km north
  4. 3 km south

Explanation

The east and west legs of 4 km cancel each other, leaving only the 3 km northward leg. The final displacement is therefore 3 km north of the start.

Question 43Reasoning Ability

In a family of three generations, Ram is the father of Sita. Sita is the mother of Gita. Mohan is the son of Ram. How is Mohan related to Gita?

  1. Maternal uncle Correct answer.
  2. Brother
  3. Grandfather
  4. Paternal uncle

Explanation

Gita's mother is Sita, and Mohan is Sita's brother because both are children of Ram. The brother of one's mother is the maternal uncle, so Mohan is Gita's maternal uncle.

Question 44Reasoning Ability

Which of the following numbers does not belong with the others: 64, 125, 216, 250?

  1. 250 Correct answer.
  2. 216
  3. 125
  4. 64

Explanation

64 = 4³, 125 = 5³ and 216 = 6³ are all perfect cubes, whereas 250 is not a perfect cube. The odd one out is therefore 250.

Question 45Reasoning Ability

Six people A, B, C, D, E and F are arranged in increasing order of age. A is older than only B. C is older than A but younger than D. F is the oldest. Who is the second oldest?

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

Explanation

With F oldest and A older than only B, the youngest two are B then A. Since C is older than A but younger than D, and E is unplaced, E must be the second oldest and D the third, making D the second oldest only if E is older; checking order F, E, D, C, A, B gives D as third oldest, so re-evaluating shows E is second and D third.

Question 46Reasoning Ability

A statement and conclusion are given. Statement: Some banks are private. All private entities are regulated. Conclusion: Some banks are regulated. Does the conclusion follow?

  1. No, it does not follow
  2. Only if no bank is regulated
  3. Only if all banks are private
  4. Yes, it follows Correct answer.

Explanation

The banks that are private fall under the class of regulated entities, so at least some banks are regulated. This is a valid inference from the two given statements.

Question 47Reasoning Ability

If 1st January of a non-leap year is a Monday, what day of the week is 1st March of the same year?

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

Explanation

January has 31 days and February has 28 in a non-leap year, totalling 59 days before 1st March. Since 59 ÷ 7 leaves remainder 3, the day advances three places from Monday to Thursday.

Question 48Reasoning Ability

In a code language, 'SUN' is written as 'RTM' and 'MOON' is written as 'LNNM'. How is 'STAR' written in the same code?

  1. RSZR
  2. RTZQ
  3. RSZQ Correct answer.
  4. QSZQ

Explanation

Every letter is shifted one place backward: S→R, T→S, A→Z, R→Q, giving RSZQ. The backward shift must be applied uniformly, including to the letter A, which wraps to Z.

Question 49Reasoning Ability

Five houses stand in a row. The blue house is to the right of the red house but to the left of the green house. The yellow house is to the left of the red house. The white house is to the right of the green house. Which house is in the middle?

  1. Yellow
  2. Green
  3. Red Correct answer.
  4. Blue

Explanation

The order from left to right is yellow, red, blue, green, white. The middle (third) house in this five-house row is the blue house, with two houses on each side. Rechecking the chain of left-right clues confirms this single order.

Question 50Reasoning Ability

A series of figures follows the rule: the number of sides increases by one each step, starting from a triangle. What is the number of sides in the fifth figure?

  1. 6
  2. 8
  3. 5
  4. 7 Correct answer.

Explanation

The sides progress as 3, 4, 5, 6, 7 for the first five figures, since each step adds one side. The fifth figure therefore has 7 sides.
