Question 1Reasoning Ability / General Intelligence

Find the next term in the number series: 5, 11, 23, 47, ?

  1. 94
  2. 96
  3. 91
  4. 95 Correct answer.

Explanation

Each term is obtained by doubling the previous term and adding 1: 5 × 2 + 1 = 11, 11 × 2 + 1 = 23, 23 × 2 + 1 = 47, so the next term is 47 × 2 + 1 = 95. The same answer appears if you double the successive differences (6, 12, 24, 48), which confirms the pattern.

Question 2Reasoning Ability / General Intelligence

In a certain code language, BANK is written as CBOJ. Using the same rule, how will LOAN be written?

  1. MPBM Correct answer.
  2. LPBM
  3. NPBM
  4. MPBN

Explanation

Comparing BANK with CBOJ shows that the first three letters each move one place forward while the fourth letter moves one place backward. Applying this to LOAN gives L→M, O→P, A→B and N→M, so the code is MPBM.

Question 3Reasoning Ability / General Intelligence

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

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

Explanation

The only son of Ravi's grandfather is Ravi's own father, because the grandfather has just one son. The daughter of Ravi's father is therefore Ravi's sister, since the person in the photograph is female.

Question 4Reasoning Ability / General Intelligence

A man starts from his office, walks 5 km towards north, turns right and walks 3 km, turns right again and walks 5 km, and finally turns left and walks 2 km. How far and in which direction is he from his office?

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

Explanation

Taking the office as the origin, he reaches (0, 5), then (3, 5) after moving east, then (3, 0) after moving south. Facing south, his left is east, so the final 2 km places him at (5, 0), that is, 5 km east of the office.

Question 5Reasoning Ability / General Intelligence

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

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

Explanation

The particular statement "Some books are chairs" converts simply to "Some chairs are books", so conclusion II is valid. Conclusion I is not certain because the books that happen to be chairs may be among the books that are not pens.

Question 6Reasoning Ability / General Intelligence

Five friends P, Q, R, S and T sit in a row facing north. Q sits at the extreme left end and T at the extreme right end. R sits second to the right of Q, and S sits between R and T. Who sits second from the right end?

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

Explanation

Numbering the seats 1 to 5 from the left, Q is at 1, R is at 3 and T is at 5. S must occupy seat 4 to be between R and T, which leaves seat 2 for P, so the person second from the right is S.

Question 7Reasoning Ability / General Intelligence

In a row of 45 students, Anil is 15th from the left end and Sunil is 20th from the right end. How many students sit between Anil and Sunil?

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

Explanation

Sunil's position from the left is 45 − 20 + 1 = 26. Anil is at position 15, so the number of students between them is 26 − 15 − 1 = 10.

Question 8Reasoning Ability / General Intelligence

Statements: M > N ≥ O = P; Q ≤ P. Which conclusion is definitely true? Conclusions: I. M > Q. II. O ≥ Q.

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

Explanation

Combining the statements gives M > N ≥ O = P ≥ Q. Since M is greater than O and O is at least Q, M is strictly greater than Q, so conclusion I holds. Also O = P ≥ Q, so conclusion II holds as well.

Question 9Reasoning Ability / General Intelligence

Six persons A, B, C, D, E and F live on six different floors of a building numbered 1 to 6 from bottom to top. F lives on floor 1. C lives on an even-numbered floor above B. Exactly two persons live between A and C. B lives immediately above D. Who lives on floor 4?

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

Explanation

With F on floor 1, C must be on floor 6 because C on floor 4 would force A onto floor 1, already taken by F, and C on floor 2 is not above B. Hence A is on floor 3, and the only adjacent pair B above D that fits the remaining floors 2, 4 and 5 is D on 4 and B on 5, leaving E on 2.

Question 10Reasoning Ability / General Intelligence

In a certain code language: 'fan is old' is written as 'la pa ta'; 'old is gold' is written as 'ta na pa'; 'gold is metal' is written as 'na ta ja'; 'metal is hard' is written as 'ja ta ka'. What is the code for 'gold'?

  1. na Correct answer.
  2. ka
  3. pa
  4. ja

Explanation

The word 'is' appears in all four sentences, so its code is the common word 'ta'. From the second sentence, 'gold' pairs with 'na' since 'old' is already 'pa', confirmed by 'gold is metal' giving 'na ta ja'. Therefore the code for 'gold' is 'na'.

Question 11Reasoning Ability / General Intelligence

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

  1. 68
  2. 78 Correct answer.
  3. 82
  4. 74

Explanation

The pattern is to double each term and add 2: 3×2+2=8, 8×2+2=18, and 18×2+2=38. Applying the same rule gives 38×2+2=78, so 78 is the next term.

Question 12Reasoning Ability / General Intelligence

In a certain code, TREE is written as VTGG. Using the same rule, how is LEAF written?

  1. NGCH Correct answer.
  2. MGCH
  3. NGCI
  4. NGBH

Explanation

Each letter of TREE is shifted two places forward in the English alphabet: T→V, R→T, E→G and E→G. Applying the same shift to LEAF gives L→N, E→G, A→C and F→H, producing NGCH.

Question 13Reasoning Ability / General Intelligence

Five colleagues Anil, Bina, Chirag, Deepa and Esha sit in a row facing north. Anil is second from the left. Esha is at the extreme right. Bina sits immediately to the right of Anil. Deepa sits between Bina and Esha. Who sits in the middle?

  1. Deepa
  2. Anil
  3. Bina Correct answer.
  4. Chirag

Explanation

Placing Anil second from the left and Esha at the extreme right gives positions 2 and 5. Bina must be immediately right of Anil at position 3, and Deepa must occupy position 4 between Bina and Esha. The middle seat is therefore Bina's.

Question 14Reasoning Ability / General Intelligence

P is the brother of Q. Q is the mother of R. S is the father of P. How is S related to R?

  1. Mother's father Correct answer.
  2. Father's brother
  3. Mother's brother
  4. Father's father

Explanation

P is Q's brother, so Q and P are siblings, and S is their father. Since Q is R's mother, S is R's mother's father, that is, R's maternal grandfather.

Question 15Reasoning Ability / General Intelligence

A bank officer walks 4 km north from her office, turns right and walks 3 km, turns right again and walks 4 km, and then turns left and walks 2 km. In which direction is she from her office?

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

Explanation

From the office, 4 km north followed by 3 km east and 4 km south returns the officer to the east-west line through the office. The final left turn from south faces east, adding 2 km east, so the final position is 5 km due east.

Question 16Reasoning Ability / General Intelligence

Statements: All chairs are tables. Some tables are sofas. Conclusions: I. Some chairs are sofas. II. Some sofas are tables. Which conclusion definitely follows?

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

Explanation

The statement 'Some tables are sofas' converts to 'Some sofas are tables', so conclusion II definitely follows. The chairs are all tables, but nothing guarantees that any chair is among the sofas, so conclusion I does not follow.

Question 17Reasoning Ability / General Intelligence

In a row of 30 candidates, Asha is 9th from the left end. Bala is 5th to the right of Asha. What is Bala's position from the right end?

  1. 17th Correct answer.
  2. 15th
  3. 16th
  4. 18th

Explanation

Asha is 9th from the left, and Bala is 5 places to her right, so Bala is 14th from the left. In a row of 30, the position from the right is 30 − 14 + 1 = 17, so Bala is 17th from the right.

Question 18Reasoning Ability / General Intelligence

Statements: L ≤ M < N = O ≥ P > Q. Conclusions: I. M < O. II. Q < N. III. L ≤ P. Which conclusions are definitely true?

  1. Only II and III
  2. Only II
  3. Only I and II Correct answer.
  4. Only I and III

Explanation

From L ≤ M < N = O, we get M < O, so conclusion I is true. Also N = O ≥ P > Q gives N > Q, so conclusion II is true. No relation between L and P is forced, so III is not definite.

Question 19Reasoning Ability / General Intelligence

Six employees A, B, C, D, E and F live on six different floors of a building numbered 1 to 6 from bottom to top. A lives on floor 4. B lives immediately above D and above floor 4. C lives on an odd-numbered floor below A, and no one lives below C. E lives immediately above F. Who lives on floor 6?

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

Explanation

B is immediately above D and above floor 4, so B must be on floor 6 and D on floor 5. C must be on floor 1 because it is odd, below A on floor 4, and has no floor below it. E is immediately above F, so F and E occupy floors 2 and 3, leaving A on floor 4 and B on floor 6.

Question 20Reasoning Ability / General Intelligence

In a certain code, a word is coded as the sum of the positions of its letters in the English alphabet. If PEN is coded as 35, what is the code for BOOK?

  1. 45
  2. 42
  3. 43 Correct answer.
  4. 41

Explanation

The code adds the alphabet positions of all letters. PEN gives 16 + 5 + 14 = 35, confirming the rule. For BOOK, 2 + 15 + 15 + 11 = 43.

Question 21Reasoning Ability / General Intelligence

Find the next term in the number series: 12, 17, 15, 20, 18, ?

  1. 23 Correct answer.
  2. 21
  3. 25
  4. 22

Explanation

The series alternates two operations: add 5, then subtract 2. Starting from 18, the next operation is add 5, giving 23.

Question 22Reasoning Ability / General Intelligence

Find the next term in the letter series: AZ, BY, CX, DW, ?

  1. FV
  2. EU
  3. EV Correct answer.
  4. EW

Explanation

The first letters move forward alphabetically A, B, C, D, so next is E. The second letters move backward Z, Y, X, W, so next is V. Therefore the next term is EV.

Question 23Reasoning Ability / General Intelligence

Four number groups are given. Three share a common property. Which group is the odd one out?

  1. 121
  2. 144
  3. 180 Correct answer.
  4. 169

Explanation

121, 144 and 169 are perfect squares of 11, 12 and 13 respectively. 180 is not a perfect square, so it is the odd group.

Question 24Reasoning Ability / General Intelligence

In a certain code, every consonant is replaced by the next letter in the English alphabet and every vowel is replaced by the previous letter. How is RIVER written in that code?

  1. SHWDS Correct answer.
  2. SHWDR
  3. SJWDS
  4. QHWDQ

Explanation

Consonants move one step forward (R→S, V→W), while vowels move one step backward (I→H, E→D). Applying this to RIVER gives S H W D S, that is SHWDS.

Question 25Reasoning Ability / General Intelligence

A bank officer starts from point P, walks 8 m east, turns left and walks 6 m, turns left and walks 8 m, and then turns right and walks 5 m. How far and in which direction is she from P?

  1. 10 m north
  2. 11 m south
  3. 5 m north
  4. 11 m north Correct answer.

Explanation

After 8 m east, 6 m north, 8 m west and 5 m north, the east-west displacements cancel. The officer is 6 + 5 = 11 m north of P.

Question 26Reasoning Ability / General Intelligence

Six bank employees A, B, C, D, E and F sit around a circular table facing the centre. A sits opposite D. B sits immediate right of A. C sits immediate left of D. E sits opposite B. Who sits immediate right of F?

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

Explanation

With A and D opposite, B is placed immediate right of A and C immediate left of D. E opposite B fixes the remaining seat, leaving F between A and E; the immediate right of F is A.

Question 27Reasoning Ability / General Intelligence

Statements: No coin is a note. Some notes are cards. Conclusions: I. Some cards are not coins. II. No card is a coin. Which conclusion(s) follow(s)?

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

Explanation

The notes that are cards are notes, and no coin is a note, so those cards cannot be coins. Hence some cards are not coins; conclusion II is too strong because other cards may be coins.

Question 28Reasoning Ability / General Intelligence

Among five bank employees R, S, T, U and V, R scored more than S but less than T. U scored more than T, and V scored less than S. Who scored the highest?

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

Explanation

Combining the comparisons gives U > T > R > S > V. Therefore U has the highest score.

Question 29Reasoning Ability / General Intelligence

Five bank employees A, B, C, D and E live on five different floors of a building numbered 1 to 5 from bottom to top. A lives on floor 3. B lives immediately above C. D does not live on floor 1. E lives below A. Who lives on floor 1?

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

Explanation

A is on floor 3. If B were immediately above C on floors 2 and 1, E would have no floor below 3, so B and C must be on floors 5 and 4. The remaining floors 1 and 2 go to E and D, and D cannot be on floor 1, so E is on floor 1.

Question 30Reasoning Ability / General Intelligence

In a coded inequality, 'P $ Q' means P is greater than Q; 'P @ Q' means P is greater than or equal to Q; 'P % Q' means P is less than or equal to Q; and 'P & Q' means P is equal to Q. Statements: P $ Q @ R % S & T. Which conclusions are definitely true? I. P > S II. Q ≥ R III. R ≤ T

  1. Only I and II
  2. All I, II and III
  3. Only II and III Correct answer.
  4. Only I and III

Explanation

The statement translates to P > Q ≥ R ≤ S = T. Q ≥ R follows directly, and R ≤ S = T gives R ≤ T. P > S is not certain because P and S are only linked through values at or below Q, so only II and III are definite.

Question 31Reasoning Ability / General Intelligence

A bank's token counter displays the sequence 5, 11, 23, 47, ?. If the same pattern continues, which number should appear next?

  1. 95 Correct answer.
  2. 89
  3. 96
  4. 94

Explanation

Each term is obtained by doubling the previous term and adding 1: 5×2+1=11, 11×2+1=23, and 23×2+1=47. Applying the same rule gives 47×2+1=95.

Question 32Reasoning Ability / General Intelligence

In a certain bank's internal code, the word LOAN is written as MPBO. Using the same rule, how is CASH written?

  1. DBTH
  2. DBTJ
  3. DBTI Correct answer.
  4. CBTI

Explanation

Each letter of LOAN moves one place forward in the English alphabet: L→M, O→P, A→B, N→O. Applying the same one-step forward shift to CASH gives C→D, A→B, S→T, H→I, so the code is DBTI.

Question 33Reasoning Ability / General Intelligence

A bank's aptitude drill lists four values: 121, 144, 180 and 169. Three values are perfect squares of consecutive integers. Which value breaks the pattern?

  1. 169
  2. 180 Correct answer.
  3. 144
  4. 121

Explanation

121=11², 144=12² and 169=13², so those three are squares of consecutive integers. 180 lies between 13²=169 and 14²=196 and is not a perfect square, so it is the odd value.

Question 34Reasoning Ability / General Intelligence

A bank officer leaves her branch, walks 6 km north, turns right and walks 8 km, turns right and walks 6 km, and finally turns left and walks 2 km. How far and in which direction is she from the branch?

  1. 2 km east
  2. 10 km west
  3. 10 km east Correct answer.
  4. 8 km east

Explanation

Taking the branch as the origin, the officer moves to (0,6), then to (8,6), then to (8,0), and finally to (10,0). Her final position is 10 km east of the branch.

Question 35Reasoning Ability / General Intelligence

M is the daughter of N. N is the only son of O. P is the sister of N. How is M related to P?

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

Explanation

N is M's father, and P is N's sister, so P is M's paternal aunt. Therefore M, who is female, is P's niece.

Question 36Reasoning Ability / General Intelligence

Statements: All passbooks are registers. No register is a card. Some cards are files. Conclusions: I. No passbook is a card. II. Some files are not registers. Which conclusion(s) follow?

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

Explanation

Since every passbook is a register and no register is a card, no passbook can be a card, so I follows. The cards that are files cannot be registers, so at least some files are not registers, making II follow.

Question 37Reasoning Ability / General Intelligence

Among five bank clerks A, B, C, D and E, A scored more than B. C scored less than D. E scored more than A but less than D. Who scored the highest?

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

Explanation

From the clues, D > E > A > B, and D > C. Since D is above E, A and B, and also above C, D must have the highest score.

Question 38Reasoning Ability / General Intelligence

Five bank employees P, Q, R, S and T sit in a row facing north. R is exactly in the middle. P sits at one of the ends. S sits immediately to the right of R. Q is not adjacent to R. Who sits second from the left?

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

Explanation

R must occupy the third seat, so S is fourth. P must be at an end, and Q cannot be second or fourth; the remaining arrangements force T into the second seat from the left.

Question 39Reasoning Ability / General Intelligence

Six bank employees A, B, C, D, E and F live on six different floors numbered 1 to 6 from bottom to top. C lives on floor 1 and D on floor 3. A lives on an even-numbered floor but not floor 6. B lives immediately above F, and E lives above A but below B. Who lives on floor 5?

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

Explanation

C and D occupy floors 1 and 3, and A must be on floor 2 because floor 4 would leave no place for E below B. The B/F pair must then be floors 6 and 5 respectively, with E on floor 4. Hence F lives on floor 5.

Question 40Reasoning Ability / General Intelligence

Five bank employees P, Q, R, S and T sit around a circular table facing the centre. P sits second to the right of Q. R sits immediately to the left of P. S sits adjacent to Q. Who sits immediately to the right of T?

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

Explanation

Fix Q at a seat. P is two places to Q's right, and R is immediately to P's left. Since S must be adjacent to Q and one adjacent seat is already R, S occupies the other adjacent seat; T is left between S and P. Thus S sits immediately to the right of T.

Question 41Reasoning Ability / General Intelligence

In a bank's record system, 'Cheque' is related to 'Signature' in the same way as 'ATM card' is related to '____'.

  1. Passbook
  2. Branch
  3. Receipt
  4. PIN Correct answer.

Explanation

A cheque requires a signature to authorise the transaction, just as an ATM card requires a PIN to authorise use. The relation is instrument to the credential that validates it. Receipt, branch and passbook do not serve that validating role.

Question 42Reasoning Ability / General Intelligence

In a bank's document code, each letter is replaced by its position in the English alphabet (A=1, B=2, ..., Z=26), and the positions are written side by side in the same order as the letters. What is the code for the two-letter word 'FD'?

  1. 64 Correct answer.
  2. 65
  3. 54
  4. 46

Explanation

In the given code, F is the 6th letter and D is the 4th letter. Writing the positions in the same order as the letters gives 6 followed by 4, that is 64.

Question 43Reasoning Ability / General Intelligence

K is the brother of L. L is the mother of M. How is K related to M?

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

Explanation

K is L's brother, so K is the brother of M's mother. The brother of one's mother is called the maternal uncle. A paternal uncle would be the father's brother, which the given relation does not establish.

Question 44Reasoning Ability / General Intelligence

Five bank employees A, B, C, D and E stand in a queue facing north. E is at the front. C is immediately ahead of A. B is behind D but ahead of C. Who is exactly in the middle of the queue?

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

Explanation

E occupies the first position. Since B is behind D but ahead of C, and C is immediately ahead of A, the remaining places must be D, B, C, A in that order. Thus B is in the third position, which is the middle of the five-person queue.

Question 45Reasoning Ability / General Intelligence

Statements: All ATMs are machines. Some machines are cash dispensers. Conclusions: I. Some ATMs are cash dispensers. II. Some machines are ATMs. Which conclusion logically follows?

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

Explanation

From 'All ATMs are machines', the valid conversion is 'Some machines are ATMs', so conclusion II follows. The statement about cash dispensers concerns only machines and gives no definite link to ATMs, so conclusion I is not forced.

Question 46Reasoning Ability / General Intelligence

Find the next term in the number series: 3, 6, 11, 18, 27, ?

  1. 36
  2. 40
  3. 38 Correct answer.
  4. 39

Explanation

The differences between successive terms are 3, 5, 7 and 9, increasing by 2 each time. The next difference should be 11, so the next term is 27 + 11 = 38.

Question 47Reasoning Ability / General Intelligence

A bank courier starts facing north. He turns 90° clockwise, then 180°, and then 90° anticlockwise. Which direction is he facing now?

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

Explanation

Starting from north, a 90° clockwise turn makes him face east. A further 180° turn makes him face west, and then a 90° anticlockwise turn from west makes him face south.

Question 48Reasoning Ability / General Intelligence

In a bank's staff-record code, 'A @ B' means A is the mother of B, and 'A # B' means A is the father of B. In the expression 'X # Y @ Z', how is X related to Z?

  1. Maternal grandmother
  2. Paternal grandfather
  3. Maternal grandfather Correct answer.
  4. Maternal uncle

Explanation

X # Y makes X the father of Y, and Y @ Z makes Y the mother of Z. Therefore X is the father of Z's mother, which means X is Z's maternal grandfather.

Question 49Reasoning Ability / General Intelligence

In a certain code, 'bank work is fast' is written as 'ta re mo pa'; 'work fast and clean' is written as 're pa ni ka'; and 'bank clean today' is written as 'ta ni ja'. What is the code for 'is'?

  1. pa
  2. ta
  3. re
  4. mo Correct answer.

Explanation

The word 'bank' appears in the first and third sentences and is coded 'ta'. 'Work' and 'fast' appear in the first two sentences and are coded 're' and 'pa' in some order. The only word left in the first sentence is 'is', so its code must be 'mo'.

Question 50Reasoning Ability / General Intelligence

Among four bank employees P, Q, R and S, who has the lowest salary? Statement I: P earns more than R but less than Q. Statement II: S earns more than Q. Which of the statements is/are sufficient to answer the question?

  1. Statement I alone is sufficient
  2. Neither statement alone nor both together are sufficient
  3. Both statements together are sufficient Correct answer.
  4. Statement II alone is sufficient

Explanation

Statement I gives Q > P > R but says nothing about S, so S could still be lower than R. Statement II gives S > Q but does not compare S with P or R. Together they give S > Q > P > R, so R is the lowest earner.
