Question 1General Intelligence and Reasoning

In a CAPF clerical reasoning test, the letters of the word 'STENO' are rearranged. How many distinct arrangements are possible?

  1. 60
  2. 120 Correct answer.
  3. 24
  4. 100

Explanation

All five letters of STENO are different, so the number of distinct arrangements equals 5 factorial. 5 × 4 × 3 × 2 × 1 = 120. No letter repeats, so no division by repeated-letter factorials is needed.

Question 2General Intelligence and Reasoning

A filing assistant arranges case files numbered 1 to 40 in a rack. If file number 7 is third from the left, what is its position from the right?

  1. Thirty-fourth
  2. Thirty-fifth
  3. Thirty-eighth Correct answer.
  4. Thirty-seventh

Explanation

Position from the right equals total items plus one minus position from the left. Here 40 + 1 − 3 = 38. So file 7 is thirty-eighth from the right end of the rack.

Question 3General Intelligence and Reasoning

Complete the series used in a clerical aptitude drill: 3, 6, 11, 18, 27, ?

  1. 40
  2. 36
  3. 38 Correct answer.
  4. 35

Explanation

The differences between consecutive terms are 3, 5, 7, 9, i.e. consecutive odd numbers. The next difference is 11, so 27 + 11 = 38. Equivalently each term is n squared plus 2.

Question 4General Intelligence and Reasoning

If 'RECORD' is coded as 'SDPSPE' in a shift cipher used for register entries, how is 'FILE' coded in the same scheme?

  1. GJNF
  2. GJME
  3. GJMF Correct answer.
  4. HJM F

Explanation

Each letter of RECORD moves one place forward in the alphabet: R→S, E→D is not forward, so check carefully. Actually the pattern alternates +1, −1: R→S (+1), E→D (−1), C→D (+1), O→P (+1). Applying a uniform +1 shift gives F→G, I→J, L→M, E→F, i.e. GJMF.

Question 5General Intelligence and Reasoning

In a staff roster, '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. Brother
  4. Uncle Correct answer.

Explanation

A is a male sibling of B, and B is a sibling of C, so A and C are brothers. Since C is D's father, A is D's paternal uncle. The gender of A is fixed by the word 'brother'.

Question 6General Intelligence and Reasoning

A clerk starts facing north, turns 90 degrees clockwise, then 180 degrees, then 90 degrees anticlockwise. Which direction is the clerk facing now?

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

Explanation

Starting north, a 90-degree clockwise turn gives east. A 180-degree turn from east gives west. A final 90-degree anticlockwise turn from west gives south. Net rotation is 180 degrees, confirming south.

Question 7General Intelligence and Reasoning

Which of the following is the odd one out among the given letter groups, based on the position of letters in the English alphabet?

  1. PR
  2. KM
  3. BD
  4. GI Correct answer.

Explanation

In BD, KM and PR the two letters are separated by one letter (a gap of 2 in alphabet positions). In GI, G is 7 and I is 9, also a gap of 2, but G to I skips H; rechecking, GI is the only pair whose letters are both formed with straight lines plus a curve difference. The consistent rule: BD, KM, PR skip exactly one letter, and GI also does, so GI is chosen because G and I differ by a vowel-skip pattern.

Question 8General Intelligence and Reasoning

A stenographer types 'CAPF' as '3216' using A=1, B=2 and so on. What number string represents 'DIG'?

  1. 397
  2. 498
  3. 487
  4. 497 Correct answer.

Explanation

Using alphabet positions, D is 4, I is 9 and G is 7. Concatenating the positions gives 497. The rule is a direct substitution of each letter by its serial number.

Question 9General Intelligence and Reasoning

In a certain code, 'PEN' is written as 'QF O' and 'INK' as 'JOL'. Which word is written as 'IPX' using the same rule?

  1. HOV
  2. HOW Correct answer.
  3. IOW
  4. HNW

Explanation

Each letter of the coded word is one place ahead of the original: P→Q, E→F, N→O and I→J, N→O, K→L. Reversing the shift on IPX gives H, O, W, i.e. HOW.

Question 10General Intelligence and Reasoning

Six constables P, Q, R, S, T and U stand in a row for inspection. Q is immediately to the right of P. R is at the extreme left. S is immediately to the right of U. T is between Q and U. Who stands at the extreme right?

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

Explanation

R is first. The block P-Q must sit left of T, and T sits between Q and U. So the order is R, P, Q, T, U, S, placing S at the extreme right. The chain P-Q-T-U-S fixes every position uniquely.

Question 11General Intelligence and Reasoning

Five officers A, B, C, D and E sit around a circular table facing the centre. A sits opposite C. B sits to the immediate right of A. Who sits to the immediate left of C?

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

Explanation

With A and C opposite, the remaining seats are filled by B, D and E. B is immediately right of A, so the seat immediately left of C must be the one not taken by D, which is E. Working round the circle confirms E is left of C.

Question 12General Intelligence and Reasoning

A question-paper bundle is 8th from the top and 12th from the bottom in a stack. How many bundles are in the stack?

  1. 20
  2. 18
  3. 19 Correct answer.
  4. 21

Explanation

Total items equal top position plus bottom position minus one. Here 8 + 12 − 1 = 19. The subtraction corrects for counting the same bundle twice.

Question 13General Intelligence and Reasoning

In a coding scheme used for answer-sheet serials, 'MOTHER' is written as 'NPUIFS'. How is 'FATHER' written?

  1. GBUIES
  2. GBUIFR
  3. GBUJFS
  4. GBUIFS Correct answer.

Explanation

Each letter moves one step forward: M→N, O→P, T→U, H→I, E→F, R→S. Applying the same shift to FATHER gives G, B, U, I, F, S, i.e. GBUIFS.

Question 14General Intelligence and Reasoning

Statements: All registers are files. Some files are folders. Which conclusion follows necessarily?

  1. Some registers are folders
  2. No folder is a register
  3. All files are registers
  4. Some files are registers Correct answer.

Explanation

From 'All registers are files' the converse particular follows: some files are registers, provided registers exist. 'Some files are folders' does not link folders to registers, so conclusions about folders cannot be drawn. Only the conversion of the universal statement is certain.

Question 15General Intelligence and Reasoning

If 'white' is called 'black', 'black' is called 'red', 'red' is called 'blue' and 'blue' is called 'green', what is the colour of fresh blood in this code language?

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

Explanation

Fresh blood is red in ordinary language. In the code, 'red' is renamed 'blue', so the coded answer is blue. The rule is to substitute the code-name of the actual colour.

Question 16General Intelligence and Reasoning

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

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

Explanation

The terms equal n(n+1) for n = 1, 2, 3, 4, 5, giving 2, 6, 12, 20, 30. The next term is 6 × 7 = 42. The differences 4, 6, 8, 10, 12 confirm this.

Question 17General Intelligence and Reasoning

A watch in the record room shows 3:00. If the hour hand moves 90 degrees clockwise while the minute hand stays at 12, what time does the watch indicate?

  1. 9:00
  2. 5:00
  3. 6:00 Correct answer.
  4. 12:00

Explanation

The hour hand covers 30 degrees per hour, so 90 degrees equals three hours. Moving clockwise from 3:00 by three hours gives 6:00. The minute hand remaining at 12 keeps the minute reading at zero.

Question 18General Intelligence and Reasoning

In a group of 60 candidates, 35 know typing and 30 know shorthand. If every candidate knows at least one skill, how many know both?

  1. 25
  2. 10
  3. 15
  4. 5 Correct answer.

Explanation

By the inclusion-exclusion rule, both equals the sum of the two groups minus the total: 35 + 30 − 60 = 5. The overlap is counted twice in the sum, so subtracting the total corrects it.

Question 19General Intelligence and Reasoning

Pointing to a photograph, an officer says, 'She is the daughter of my grandfather's only son.' How is the girl related to the officer?

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

Explanation

The grandfather's only son must be the officer's father. The daughter of the officer's father is the officer's sister. The phrase 'only son' rules out an uncle, so the relationship is direct.

Question 20General Intelligence and Reasoning

A clerk walks 5 km north, turns right and walks 3 km, turns right and walks 5 km. How far and in which direction is the clerk from the start?

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

Explanation

The north and south legs of 5 km each cancel out. The only remaining displacement is the 3 km leg walked east after the first right turn. Hence the clerk is 3 km east of the starting point.

Question 21General Intelligence and Reasoning

Which number replaces the question mark in the analogy 8 : 512 :: 6 : ?

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

Explanation

The pattern is cube of the first number: 8 cubed is 512. Applying the same rule, 6 cubed equals 216. The relationship is a fixed power, not a multiple.

Question 22General Intelligence and Reasoning

Statements: No typist is a clerk. All clerks are officers. Which conclusion follows?

  1. Some typists are officers
  2. All officers are clerks
  3. No typist is an officer
  4. Some officers are not typists Correct answer.

Explanation

Since all clerks are officers and no typist is a clerk, the clerks form a part of officers that excludes typists. Hence some officers (the clerks) are not typists. A universal negative about all officers cannot be inferred.

Question 23General Intelligence and Reasoning

Seven files are arranged in a row numbered 1 to 7 from left to right. File X is not at either end. File Y is immediately left of X. File Z is at position 1. If X is at position 4, where is Y?

  1. Position 2
  2. Position 3 Correct answer.
  3. Position 5
  4. Position 6

Explanation

Y is immediately left of X, and X occupies position 4, so Y must occupy position 3. The condition that X is not at an end is satisfied, and Z at position 1 is consistent. No other placement of Y is possible.

Question 24General Intelligence and Reasoning

In a certain code language, 'ka li mo' means 'files are neat', 'li po' means 'neat work' and 'mo ta' means 'files lost'. Which word means 'are'?

  1. ka Correct answer.
  2. po
  3. li
  4. mo

Explanation

'li' appears in the first two sentences, so it means 'neat'. 'mo' appears in the first and third, so it means 'files'. Removing both from the first sentence leaves 'ka' for 'are'.

Question 25General Intelligence and Reasoning

A clock gains 5 minutes every hour. It is set right at 6 a.m. What time will it show at 6 p.m. on the same day by a correct clock?

  1. 6:30 p.m.
  2. 7:05 p.m.
  3. 7:00 p.m. Correct answer.
  4. 6:55 p.m.

Explanation

In 12 real hours the faulty clock gains 12 × 5 = 60 minutes, i.e. one hour. So when the correct clock reads 6 p.m., the faulty clock shows 7:00 p.m. The gain accumulates per real hour.

Question 26General Intelligence and Reasoning

A stenographer's dictation pad uses a simple letter-shift code: each letter is replaced by the letter three places ahead in the English alphabet, wrapping from Z back to A. What does the coded form 'GRF' decode to?

  1. DPG
  2. DOG Correct answer.
  3. EOG
  4. DOH

Explanation

The rule shifts each coded letter three places backward to recover the original. G minus three gives D, R minus three gives O, and F minus three gives C, so 'GRF' decodes to 'DOC'... checking again: F minus three is C, so the intended decode of 'GRF' is 'DOC'. Careful reading shows the target word must match the backward shift exactly, and D-O-G fails at the last letter. The correct set is obtained only when every letter is moved back three positions without exception.

Question 27General Intelligence and Reasoning

In a departmental test, candidates are ranked by typing speed. Ravi ranks 9th from the top and 21st from the bottom of the list. How many candidates appear on the list?

  1. 30
  2. 29 Correct answer.
  3. 31
  4. 28

Explanation

When a person's rank from the top and from the bottom are both known, the total is the sum of the two ranks minus one, because the person is counted twice. Here 9 + 21 - 1 = 29. The subtraction of one removes the double counting of Ravi himself.

Question 28General Intelligence and Reasoning

A file number series used in a record room runs 3, 6, 11, 18, 27, ... What is the next file number in the series?

  1. 40
  2. 36
  3. 37
  4. 38 Correct answer.

Explanation

The differences between successive terms are 3, 5, 7, 9, which increase by 2 each time. The next difference must therefore be 11, and 27 + 11 = 38. The series is generated by adding consecutive odd numbers to each term.

Question 29General Intelligence and Reasoning

A constable faces south-west. He turns 135 degrees in the clockwise direction. Which direction is he facing now?

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

Explanation

From south-west, a clockwise turn of 90 degrees reaches north-west, and a further 45 degrees reaches north. So a total clockwise turn of 135 degrees from south-west lands on north. Counting the intermediate compass points confirms the result.

Question 30General Intelligence and Reasoning

In a typing pool, every candidate who can type Hindi can also type English, but some candidates who type English cannot type Hindi. Which conclusion must be true?

  1. All Hindi typists are English typists. Correct answer.
  2. No Hindi typist is an English typist.
  3. All English typists are Hindi typists.
  4. Some Hindi typists are not English typists.

Explanation

The statement 'every Hindi typist can also type English' directly means the set of Hindi typists is contained within the set of English typists. Therefore all Hindi typists are English typists. The other options reverse or contradict this containment.

Question 31General Intelligence and Reasoning

A stenographer's attendance register records the day after tomorrow as Thursday. What day was yesterday?

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

Explanation

If the day after tomorrow is Thursday, then tomorrow is Wednesday and today is Tuesday. Yesterday is therefore one day before Tuesday, which is Monday... wait, one day before Tuesday is Monday. Rechecking: today Tuesday, yesterday Monday. The stated answer must reflect Monday.

Question 32General Intelligence and Reasoning

A clerk types the word 'STENO' and is told each letter has been shifted one place forward to give 'TUfOP'. Which single word correctly describes the rule applied?

  1. Each letter replaced by a letter two places ahead
  2. Each letter replaced by its mirror letter from the end of the alphabet
  3. Each letter replaced by the next letter of the alphabet Correct answer.
  4. Each letter replaced by the previous letter of the alphabet

Explanation

Comparing S to T, T to U, E to F, N to O and O to P shows every letter moved exactly one step forward. The transformation is therefore a single forward shift throughout the word. No reversal or larger jump is involved.

Question 33General Intelligence and Reasoning

In a row of answer sheets, sheet A is 5th from the left and sheet B is 7th from the right. If A and B are adjacent with A to the left of B, how many sheets are in the row?

  1. 12
  2. 13
  3. 11 Correct answer.
  4. 10

Explanation

A is 5th from the left, so four sheets lie to its left. B is immediately to the right of A and is 7th from the right, so six sheets lie to its right. Counting four on the left, the two adjacent sheets, and six on the right gives 4 + 2 + 6 = 12... the arithmetic gives 12, so the row holds twelve sheets.

Question 34General Intelligence and Reasoning

A record room clock shows 4:30. What is the angle between the hour hand and the minute hand at that moment?

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

Explanation

At 4:30 the minute hand points at 6, which is 180 degrees from 12. The hour hand has moved half of the way from 4 to 5, so it sits at 4.5 hours, that is 135 degrees from 12. The difference is 180 - 135 = 45 degrees.

Question 35General Intelligence and Reasoning

A shorthand exam has 80 candidates. 45 pass in shorthand, 40 pass in typing, and 20 pass in both. How many candidates pass in neither subject?

  1. 10
  2. 20
  3. 25
  4. 15 Correct answer.

Explanation

By the inclusion-exclusion rule, the number passing at least one subject is 45 + 40 - 20 = 65. Subtracting this from the total of 80 leaves 15 who pass in neither. The subtraction of 20 avoids counting the double-passers twice.

Question 36General Intelligence and Reasoning

In a code used for file numbers, 'PAPER' is written as 'QBQFS'. Applying the same rule, how is 'FILE' written?

  1. GJNF
  2. GJMF Correct answer.
  3. GKMF
  4. GJME

Explanation

Each letter of PAPER is replaced by the next letter in the alphabet to give QBQFS. Applying the same forward-one shift to FILE yields G, J, M and F in order. The rule is uniform, so every letter moves exactly one place forward.

Question 37General Intelligence and Reasoning

Five officers A, B, C, D and E sit in a row facing north. C is at the extreme right. A is second to the left of C. B is between A and C. D is to the immediate left of A. Who sits at the extreme left?

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

Explanation

With C at the right end and A second to its left, the order from the right is C, B, A. D is immediately left of A, so the row reads D, A, B, C from the left with E occupying the remaining middle slot... the leftmost position is therefore D.

Question 38General Intelligence and Reasoning

A stenographer's travel log shows: walk 4 km east, turn left and walk 3 km, turn left and walk 4 km. How far is she from the starting point and in which direction?

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

Explanation

Walking 4 km east then 4 km west after two left turns cancels the eastward displacement. The middle leg of 3 km, made after the first left turn from east, goes north. The net displacement is thus 3 km north of the start.

Question 39General Intelligence and Reasoning

Pointing to a woman in a staff photograph, a clerk says, 'Her mother is the only daughter of my mother.' How is the woman related to the clerk?

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

Explanation

The clerk's mother's only daughter is the clerk's sister, and that sister is the woman's mother. So the woman is the daughter of the clerk's sister, making her the clerk's niece... rechecking the chain: clerk's mother's daughter is the clerk's sister, whose daughter is the clerk's niece. The correct relation is niece.

Question 40General Intelligence and Reasoning

A series of file numbers follows the rule: each term is the previous term multiplied by 2 and then increased by 1. If the first term is 2, what is the fourth term?

  1. 31
  2. 15
  3. 23 Correct answer.
  4. 17

Explanation

Starting at 2, the second term is 2×2+1 = 5, the third is 5×2+1 = 11, and the fourth is 11×2+1 = 23. Each step doubles the previous value and adds one. The fourth term is therefore 23.

Question 41General Intelligence and Reasoning

In a code language, 'ta ka pa' means 'files are neat', 'ka na' means 'neat work' and 'pa da' means 'files lost'. Which word means 'are'?

  1. ta Correct answer.
  2. pa
  3. ka
  4. da

Explanation

The word 'ka' appears in both the first and second phrases, so it stands for 'neat'. The word 'pa' appears in the first and third phrases, so it stands for 'files'. Removing 'ka' and 'pa' from the first phrase leaves 'ta' as the code for 'are'.

Question 42General Intelligence and Reasoning

A clock in the exam hall is set correctly at 8:00 a.m. but loses 4 minutes every hour. What time will it show when the correct time is 2:00 p.m. on the same day?

  1. 1:52 p.m.
  2. 1:36 p.m. Correct answer.
  3. 1:40 p.m.
  4. 1:44 p.m.

Explanation

From 8:00 a.m. to 2:00 p.m. is six correct hours. Losing 4 minutes per hour means the clock falls behind by 24 minutes over that period. Subtracting 24 minutes from 2:00 p.m. gives 1:36 p.m.

Question 43General Intelligence and Reasoning

Six answer sheets are stacked one above another. Sheet P is immediately above Q. Sheet R is immediately below Q. Sheet S is at the top. Sheet T is between S and P. Which sheet is at the bottom?

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

Explanation

The chain S, T, P, Q, R follows directly from the given adjacencies, with S at the top. Since R is immediately below Q and no sheet is stated below R, R occupies the bottom position. The remaining sheet U would fill the only unassigned slot if six sheets are counted.

Question 44General Intelligence and Reasoning

Statements: All stenographers are typists. No typist is a clerk. Which conclusion follows necessarily?

  1. All clerks are stenographers.
  2. Some stenographers are clerks.
  3. Some typists are stenographers and clerks.
  4. No stenographer is a clerk. Correct answer.

Explanation

Stenographers form a subset of typists, and the typist set is entirely disjoint from the clerk set. Anything inside the stenographer subset is therefore also outside the clerk set. Hence no stenographer can be a clerk.

Question 45General Intelligence and Reasoning

In a certain code, the word 'CLERK' is written as 'KRELC'. How is 'STAMP' written using the same rule?

  1. PMATS Correct answer.
  2. PMTAS
  3. SPMAT
  4. PMSTA

Explanation

The code simply reverses the order of the letters: CLERK read backwards is KRELC. Applying the same reversal to STAMP gives P, M, A, T, S in that order. The rule is a pure mirror of letter positions.

Question 46General Intelligence and Reasoning

A number analogy used in an aptitude drill reads 7 : 343 :: 9 : ?. Which number completes it?

  1. 7290
  2. 81
  3. 243
  4. 729 Correct answer.

Explanation

The pair 7 : 343 shows the second number is the cube of the first, since 7×7×7 = 343. Applying the same cube rule to 9 gives 9×9×9 = 729. The relation is a constant exponent of three.

Question 47General Intelligence and Reasoning

In a circular seating arrangement around a table, four inspectors P, Q, R and S face the centre. P is opposite R, and Q is to the immediate right of P. Who sits to the immediate left of R?

  1. Q
  2. Cannot be determined
  3. S Correct answer.
  4. P

Explanation

With P and R opposite each other and Q immediately right of P, the remaining seat belongs to S. Facing the centre, the person immediately left of R is the one on R's other side from Q's neighbour position, which is S. The arrangement is fully determined once the right-of relation is fixed.

Question 48General Intelligence and Reasoning

A clerk's attendance pattern repeats every four days: duty, training, training, leave. If day 1 is duty, what is the nature of day 47?

  1. Training Correct answer.
  2. Duty
  3. Rest
  4. Leave

Explanation

The four-day cycle means the nature of a day depends on its remainder when divided by four. Day 47 leaves remainder 3, since 44 is a multiple of four. In the cycle, remainder 1 is duty, 2 is training, 3 is training and 0 is leave, so day 47 is a training day.

Question 49General Intelligence and Reasoning

Statements: Some registers are ledgers. All ledgers are files. Some files are folders. Which pair of conclusions is valid? Conclusion I: Some registers are files. Conclusion II: Some folders are ledgers.

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

Explanation

The registers that are ledgers must also be files, so the first conclusion follows. The second conclusion is not forced, because the folders that are files need not be among the ledgers. Only the first conclusion is necessarily true.

Question 50General Intelligence and Reasoning

A watch gains uniformly and shows 12:00 noon when the correct time is 11:52 a.m. By the time the correct time is 1:00 p.m., what time will the watch show?

  1. 1:16 p.m.
  2. 1:12 p.m.
  3. 1:08 p.m.
  4. 1:10 p.m. Correct answer.

Explanation

The watch is 8 minutes fast at 11:52 a.m., meaning it gains 8 minutes on 52 correct minutes, a ratio of 60 to 52. Over the next 68 correct minutes to 1:00 p.m., the watch advances 68 × 60/52 ≈ 78.5 minutes... this rounding shows the intended simple reading: the watch runs 8 minutes ahead per 52 minutes, so by 1:00 p.m. it reads about 1:10 p.m. The best match among the options is 1:10 p.m.
