IBPS Clerk 2025 Prelims Memory-Based Paper 4 October Shift 1 with Answers

Answer: (E) schooled

In 'Snowy was trained at a special military school, where he learned...', trained means taught or schooled. 'Aimed' is the sense used for pointing a weapon (to train a gun on something), which does not fit here.

Answer: (C) merely

In 'They are not just companions on the sidelines', just means only or merely. The other options are different senses of just (fair, rightful, exactly, a moment ago).

Answer: (E) They are skilled working members of a unit who help detect and respond to real threats.

The first paragraph says dogs track intruders, guard camps and sniff out explosives, and calls them valuable members of a unit who stand on the front line. Companionship and obedience are mentioned only as lesser or partial aspects, so the statement that they are skilled working members of a unit who help detect and respond to real threats captures the role best.

Answer: (C) pricked up

The next sentence says he had sensed movement, so his ears rose in alertness. 'Pricked up' is the idiom for ears rising when an animal becomes alert; the other options suggest relaxing or losing attention.

Answer: (B) Snowy's training included lessons on comforting worried soldiers.

The passage lists what Snowy learned at the military school (commands, detecting explosives, moving over rough ground, silent signals, teamwork). Comforting worried soldiers is described as something he did on his own at the outpost, not part of his training. All other statements are stated in the passage.

Answer: (D) Snowy adapted to harsh terrain and acted on his own initiative at a critical moment.

Snowy learned to move over rough and icy ground, and on the cold night he barked and ran to the fence without a moment's delay. He alerted the guards, who caught the intruders, so he did not capture anyone himself; the other statements are not supported.

Answer: (C) watchman

A sentinel is a guard who keeps watch, and the passage itself explains it as watchful, fearless and devoted. Watchman has the same meaning.

Answer: (E) It shows how an alert, trained dog can sense danger before the human guards do.

While the soldiers rested, Snowy sensed movement and alerted the guards, who then stopped the intruders. The incident illustrates the value of a trained dog's senses; nothing suggests disobedience, panic or a missing fence.

Answer: (B) Snowy was posted to the border mainly because of the colour of his coat.

His white coat only explains his name. The passage gives no link between the coat and his posting, so the statement about his posting is incorrect; the others are supported by the passage.

Answer: (D) taken

The fixed expression is 'take a step'; with 'have recently', the form is 'have taken an important step'. One does not give, build, produce or shift a step.

Answer: (E) excavation

Archaeologists uncover ruins while digging at a site, which is an excavation. The article 'an' also suits excavation. The other words do not describe digging.

Answer: (D) collaboration

After 'a rare' we need a noun meaning working together, followed by 'between archaeologists and doctors'. Collaboration fits. Merge is a verb, joint is an adjective or a body part, and togetherness means emotional closeness, not joint work.

Answer: (A) reconstruct

Imaging and 3D modelling were used to rebuild the body bone by bone, so reconstruct fits. The other verbs make no sense with 'the body of the ancient person'.

Answer: (C) insights

The collocation is 'valuable insights into' something. Perceiving and understands are verb forms, and intuition and point do not take 'into' here.

Answer: (B) remains

The skeleton and ruins are ancient remains, and the plural verb 'can guide' needs a plural noun. Decayed is an adjective, dispose a verb, ruin is singular and excesses does not fit the meaning.

Answer: (C) Both (I) and (III)

Discord means disagreement or conflict (in music, a harsh clash of sounds). (I) and (III) use it for conflict correctly. (II) is wrong because a discord is harsh and unpleasant, not soft and soothing.

Answer: (A) restrain her excitement

A modal verb such as could (not) is followed by the base form of the verb, so 'could not restrain her excitement' is correct.

Answer: (A) to curb the growing unrest

Attempt is followed by the to-infinitive, which is to plus the base form: 'attempted to curb'. 'To curbing' and 'to curbed' are not correct infinitives.

Answer: (E) No replacement required

'Tried to mask his nervousness' is correct: try takes the to-infinitive with the base form mask. No change is needed.

Answer: (A) to temper her frustration

Manage takes the to-infinitive: 'managed to temper her frustration'. It is not followed by an -ing form or a bare verb.

Answer: (A) A

The subject 'the district judge' is singular, so the verb should be 'has called', not 'have called'. The error is in part A.

Answer: (A) A

The present perfect continuous is has been + -ing: 'has been covering'. 'Has being' is wrong, so the error is in part A.

Answer: (B) B

After 'to', the base form of the verb is used: 'planning to install'. 'To installs' is wrong, so the error is in part B.

Answer: (C) C

After the modal 'will', the base form is used: 'will affect'. The error is in part C.

Answer: (E) No error

The sentence is correct: singular subject with 'was', the 'so ... that' structure, and past tense 'disrupted' matching 'yesterday'. No error.

Answer: (D) CBA

Correct sentence: 'Urban expansion often endangers heritage sites, prompting residents to demand stronger conservation laws.' The words in order are expansion (C), heritage (B), demand (A), so CBA.

Answer: (B) BAC

Correct sentence: 'Trade tensions among the largest economies have broken supply chains, pushing firms to widen their sourcing options.' The order is tensions (B), economies (A), sourcing (C), so BAC.

Answer: (C) CAB

Correct sentence: 'Warmer seas are damaging coral habitats, causing shifts in where fish species live.' The order is damaging (C), habitats (A), shifts (B), so CAB.

Answer: (A) ACB

Correct sentence: 'Although voter turnout increased in the recent election, misinformation still influenced public perception and voter behaviour.' Turnout (A) stays, then influenced (C), then behaviour (B), so ACB.

Answer: (E) No rearrangement required

The sentence already reads correctly: heavy monsoon rains, low-lying districts, officials had to evacuate residents. Swapping any of the marked words breaks the meaning, so no rearrangement is required.

Answer: (B) 166%

English books by A and B = 28 + 55 = 83. Hindi books by A = 50. Required % = 83/50 x 100 = 166%.

Answer: (E) 19

English books by X = 125% of 28 = 35. Hindi books by B = 54. Difference = 54 - 35 = 19.

Answer: (A) 3:2

Hindi by B : Urdu by A = 54 : 36 = 3 : 2.

Answer: (C) 47

Books sold by B = 55 + 54 + 32 = 141. Average = 141/3 = 47.

Answer: (D) 27

Total by A = 28 + 50 + 36 = 114. Total by B = 55 + 54 + 32 = 141. Difference = 141 - 114 = 27.

Answer: (E) 11:14

A : C = 220 : 280 = 11 : 14.

Answer: (B) 280

Total = 220 + 340 + 280 = 840. Average = 840/3 = 280.

Answer: (D) 80.95%

Required % = 340/420 x 100 = 80.95% (approx.).

Answer: (C) 210

Males = 3/(3+1) x 280 = 210.

Answer: (A) 305

Visitors to E = 420 x 5/4 = 525. Difference from A = 525 - 220 = 305.

Answer: (C) 1468

784 + 1297 = 2081; 2081 - 613 = 1468.

Answer: (A) 75

Work left to right: 225 ÷ 45 = 5; 5 ÷ 5 = 1; 1 × 75 = 75.

Answer: (B) 2

343 ÷ 512 × 64 = 343/8; 343/8 × 56 = 2401; 2401 ÷ 49 = 49. So 7^? = 49 = 7^2, hence ? = 2.

Answer: (E) 26.5

(120 + 39) = 159 and (12 - 6) = 6. 159 ÷ 6 = 26.5.

Answer: (D) 28

3080 + 6160 = 9240. ? = 9240 ÷ 330 = 28.

Answer: (B) 16

10800 ÷ 36 = 300. So 144 - 300 + ?² = 100, giving ?² = 256 and ? = 16.

Answer: (E) 9

√1225 = 35 and 3/5 of 35 = 21. ∛729 = 9 and 1/3 of 9 = 3. 21 ÷ 3 = 7, so ? - 2 = 7 and ? = 9.

Answer: (C) 60

√225 × 4 = 15 × 4 = 60. 5/8 × 160% = 5/8 × 8/5 = 1, so ? = 60.

Answer: (A) 225

225% of 2400 = 5400. ? = 5400 ÷ 24 = 225.

Answer: (D) 16

40² × 8 = 1600 × 8 = 12800; 12800 ÷ 50 = 256; 256 ÷ 16 = 16.

Answer: (A) 374

65% of 1700 = 1105; 1105 ÷ 13 = 85; 17² = 289; 85 + 289 = 374.

Answer: (D) 169

35% of 40 = 14; 14 × 10 = 140; 140 + 29 = 169.

Answer: (C) 4

Milk = 4/7 x 56 = 32 L, water = 24 L. After adding Y litres of water: 32/(24 + Y) = 8/7, so 24 + Y = 28 and Y = 4.

Answer: (E) 1600

A's capital-months = 2400 x 12 = 28800. B's = 9X. 28800 : 9X = 2 : 1, so 9X = 14400 and X = 1600.

Answer: (B) 54

Let A = 3x, B = 2x. (3x - 16)/(2x + 16) = 19/26, so 78x - 416 = 38x + 304, giving 40x = 720 and x = 18. A = 54.

Answer: (E) 744

X = 840 x 100/(1600 x 5) = 10.5%. New rate = 15.5%. Interest = 1600 x 15.5 x 3/100 = Rs 744.

Answer: (B) 144

1/2 x base x 24 = 180, so base = 15 cm. Side of square = 12 cm, area = 144 cm².

Answer: (A) 62

Let ages be 9a and 5a. (9a + 5)/(5a - 5) = 16/5, so 45a + 25 = 80a - 80, giving a = 3. Ages are 27 and 15. After 10 years: 37 + 25 = 62.

Answer: (C) 108 km

Downstream speed = 48 km/h, upstream = 42 km/h. Still-water speed = (48 + 42)/2 = 45 km/h. Reduced by 20%: 36 km/h. Distance in 3 h = 108 km.

Answer: (D) 270

X/27 - X/30 = 1, so X(30 - 27)/810 = 1, giving X = 270.

Answer: (E) 35

Let adults = a. 30a + 20(50 - a) = 1350, so 10a = 350 and a = 35.

Answer: (B) 672

Selling price of A = 1.25 x 0.9 = 1.125 times CP, so profit = 12.5% of CP = 75 and CP of A = 600. CP of B = 840. SP of B = 80% of 840 = Rs 672.

Answer: (A) 72 km/h

For equal distances, average speed = 2 x 60 x 90/(60 + 90) = 10800/150 = 72 km/h.

Answer: (C) 16.67

A's one-day work = 1/10 - 1/25 = 3/50. A alone takes 50/3 = 16.67 days.

Answer: (D) 135

Cultural = 100 - 40 - 25 = 35% = 315, so total = 900. Difference = (40 - 25)% of 900 = 135.

Answer: (C) Three

Number the positions 1 (bottom) to 8 (top). T is two places above R and P is just below T, so P is just above R. W is four places from R and below P, so W is four places below R; this needs R at 5 or 6. If R = 5, then W = 1, P = 6 and V (three places from P) = 3, leaving no room for S three places below V. So R = 6: T = 8, P = 7, W = 2, V = 4, S = 1, Q = 3 (next to W) and U = 5. Stack from top to bottom: T, P, R, U, V, Q, W, S. T, P and R are above U, so the answer is three.

Answer: (A) Box V

Number the positions 1 (bottom) to 8 (top). T is two places above R and P is just below T, so P is just above R. W is four places from R and below P, so W is four places below R; this needs R at 5 or 6. If R = 5, then W = 1, P = 6 and V (three places from P) = 3, leaving no room for S three places below V. So R = 6: T = 8, P = 7, W = 2, V = 4, S = 1, Q = 3 (next to W) and U = 5. Stack from top to bottom: T, P, R, U, V, Q, W, S. V is immediately above Q.

Answer: (D) Only II and III

Number the positions 1 (bottom) to 8 (top). T is two places above R and P is just below T, so P is just above R. W is four places from R and below P, so W is four places below R; this needs R at 5 or 6. If R = 5, then W = 1, P = 6 and V (three places from P) = 3, leaving no room for S three places below V. So R = 6: T = 8, P = 7, W = 2, V = 4, S = 1, Q = 3 (next to W) and U = 5. Stack from top to bottom: T, P, R, U, V, Q, W, S. I is false (only W is between Q and S). II is true (R is just above U). III is true.

Answer: (B) One

Number the positions 1 (bottom) to 8 (top). T is two places above R and P is just below T, so P is just above R. W is four places from R and below P, so W is four places below R; this needs R at 5 or 6. If R = 5, then W = 1, P = 6 and V (three places from P) = 3, leaving no room for S three places below V. So R = 6: T = 8, P = 7, W = 2, V = 4, S = 1, Q = 3 (next to W) and U = 5. Stack from top to bottom: T, P, R, U, V, Q, W, S. Alphabetical order from top: P, Q, R, S, T, U, V, W. Comparing with T, P, R, U, V, Q, W, S, only R (third from top) stays in place.

Answer: (E) Box Q

Number the positions 1 (bottom) to 8 (top). T is two places above R and P is just below T, so P is just above R. W is four places from R and below P, so W is four places below R; this needs R at 5 or 6. If R = 5, then W = 1, P = 6 and V (three places from P) = 3, leaving no room for S three places below V. So R = 6: T = 8, P = 7, W = 2, V = 4, S = 1, Q = 3 (next to W) and U = 5. Stack from top to bottom: T, P, R, U, V, Q, W, S. Below T: P (1st), R (2nd), U (3rd), V (4th), Q (5th).

Answer: (B) Only conclusion II follows

R > M = J > T gives R > T, so II follows. M and F are linked only through T (M > T and F ≥ T), so their relation is unknown; I does not follow.

Answer: (D) Both conclusions I and II follow

T < W < Z = D ≤ P gives P > T, so I follows. L ≤ T < W < Z gives L < Z, so II follows.

Answer: (A) Only conclusion I follows

Y > B ≥ X > C gives Y > C, so I follows. M and F meet only through C with opposite signs (M > C, F ≥ C), so II does not follow.

Answer: (B) Two

Checking every pair: 1 and 2 are adjacent in the number and adjacent in the series; 6 and 5 are adjacent in the number and in the series. No other pair qualifies, so there are two pairs.

Answer: (D) 19 m

Take C as (0, 0): B (0, 9), A (-5, 9), D (12, 0), E (12, 15), F (0, 15), G (0, 19). C and G lie on the same north-south line, 19 m apart.

Answer: (E) South-east

Take C as (0, 0): B (0, 9), A (-5, 9), D (12, 0), E (12, 15), F (0, 15), G (0, 19). D is 17 m east and 9 m south of A, so D is south-east of A.

Answer: (C) B - E

Take C as (0, 0): B (0, 9), A (-5, 9), D (12, 0), E (12, 15), F (0, 15), G (0, 19). D is south-east of A, C is south-east of A, E is south-east of G and D is south-east of F. E is north-east of B, so B - E is the odd one.

Answer: (D) Third to the right

Going clockwise (which is each person's left when facing the centre): H, K, O, X, M, P, Y, T. Counting to Y's right (anticlockwise): P, M, X. So X is third to the right of Y.

Answer: (E) Two

Going clockwise (which is each person's left when facing the centre): H, K, O, X, M, P, Y, T. Moving to T's left (clockwise) from T: H, K, then O. So two persons (H and K) sit between them.

Answer: (A) K

Going clockwise (which is each person's left when facing the centre): H, K, O, X, M, P, Y, T. To X's right (anticlockwise): O, then K.

Answer: (C) K - O

Going clockwise (which is each person's left when facing the centre): H, K, O, X, M, P, Y, T. K-P, H-M, X-T and O-Y each sit exactly opposite each other. K and O are neighbours, so K - O is the odd pair.

Answer: (B) O

Going clockwise (which is each person's left when facing the centre): H, K, O, X, M, P, Y, T. To Y's left (clockwise): T, H, K, O. O is fourth to the left (also directly opposite Y).

Answer: (A) Sixth to the right

D is at the left end (position 1), so C is at position 5 and E at 4. B is three places from E: position 7 (position 1 is taken by D). A is five places from C: position 10. Persons left of B = 6, so persons right of A = 6, giving 16 persons in all. B is at 7 and D at 1, so B is sixth to the right of D.

Answer: (D) 16

D is at the left end (position 1), so C is at position 5 and E at 4. B is three places from E: position 7 (position 1 is taken by D). A is five places from C: position 10. Persons left of B = 6, so persons right of A = 6, giving 16 persons in all. Total = 16.

Answer: (C) Eight

D is at the left end (position 1), so C is at position 5 and E at 4. B is three places from E: position 7 (position 1 is taken by D). A is five places from C: position 10. Persons left of B = 6, so persons right of A = 6, giving 16 persons in all. A is at 10 and D at 1, so 8 persons sit between them.

Answer: (D) Four

Symbols followed by an even digit: # 4, * 8, % 4, @ 2. ($ is followed by *, ^ by 9 and & by 1.) So four.

Answer: (E) 1

From the right: 5, 2, @, 3, 9, 4, %, 6, 1, &, 1. The 11th element is 1 (the one just before &).

Answer: (B) Six

Between # and %: 4 5 $ * 8 3 ^ 9 2 7 1 & 1 6. Odd digits: 5, 3, 9, 7, 1, 1 = six.

Answer: (E) &

Even digits from the left: 2, 4, 8. To the right of 8 the symbols are ^, then &. So the answer is &.

Answer: (E) None

Every digit next to a symbol on one side has a digit or an end on the other side (for example * 8 3 and & 1 6). No digit has a symbol on both sides.

Answer: (B) DFA

Using letter positions: R(18) O(15) U(21), J(10) G(7) M(13), L(12) I(9) O(15) and V(22) S(19) Y(25) all follow -3 then +6. D(4) F(6) A(1) follows +2 then -5, so DFA is the odd one.

Answer: (D) X

The letters are C (1st), A (2nd), E (4th) and I (8th). No meaningful English word can be made from A, C, E and I, so the answer is X.

Answer: (A) Father-in-law

M's wife is G's daughter. V is unmarried, so D must be the wife of V's brother, which makes B a son married to D. Among the rest, only K can be M's wife, so K is G's daughter and V and B are K's children; K has only one daughter, so V is female. G's husband must be in the family; H is her son and M and B are married to K and D, so G's husband is C. So C and G are the grandparents, their children are K and H, and K's children are V and B. C is the father of M's wife K, so C is M's father-in-law.

Answer: (B) V

M's wife is G's daughter. V is unmarried, so D must be the wife of V's brother, which makes B a son married to D. Among the rest, only K can be M's wife, so K is G's daughter and V and B are K's children; K has only one daughter, so V is female. G's husband must be in the family; H is her son and M and B are married to K and D, so G's husband is C. So C and G are the grandparents, their children are K and H, and K's children are V and B. K's children are V and B; B is a son, so K's daughter is V.

Answer: (B) Nephew

M's wife is G's daughter. V is unmarried, so D must be the wife of V's brother, which makes B a son married to D. Among the rest, only K can be M's wife, so K is G's daughter and V and B are K's children; K has only one daughter, so V is female. G's husband must be in the family; H is her son and M and B are married to K and D, so G's husband is C. So C and G are the grandparents, their children are K and H, and K's children are V and B. H is K's brother and B is K's son, so B is H's nephew.
