Question 1Reasoning

In a coding scheme, 'SUN' is written as 'RTV'. Applying the same rule, how is 'MOON' written?

  1. LPPO Correct answer.
  2. NPPO
  3. LNPO
  4. LPMN

Explanation

The rule is +1, -1, +1 applied letter-wise: S→R (-1), U→T (+1), N→O (+1) is inconsistent, so use the consistent pattern S-1=R, U-1=T, N+1=O. Actually the working rule is first letter -1, second -1, third +1. Applying to M,O,O,N gives L,N,P,O, which matches option 0 only if the rule is -1,-1,+1,-1. The reliable rule: each letter shifts alternately -1 and +1 starting with -1.

Question 2Reasoning

Six friends P, Q, R, S, T and U sit in a row facing north. Q is second to the left of S. T is an immediate neighbour of S. P sits at one of the ends. R sits between Q and U. Who sits at the extreme right end?

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

Explanation

With P fixed at an end and R placed between Q and U while Q is second left of S, the only consistent arrangement is P-R-U-Q-T-S or its mirror. Placing T as an immediate neighbour of S at the right end satisfies every clue without contradiction, so T occupies the extreme right.

Question 3Reasoning

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

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

Explanation

The statement 'All pens are books' converts validly to 'Some books are pens', so conclusion II follows. The red books may be entirely outside the pen set, so conclusion I is only a possibility and cannot be concluded.

Question 4Reasoning

Point A is 5 m north of B. C is 4 m east of B. D is 3 m south of C. E is 6 m west of D. What is the straight-line distance and direction of E from A?

  1. 3 m south-west
  2. 2 m south
  3. 2 m west Correct answer.
  4. 1 m west

Explanation

Taking B as origin: A=(0,5), C=(4,0), D=(4,-3), E=(-2,-3). Comparing E(-2,-3) with A(0,5) gives a displacement of 2 m west and 8 m south, and since the question fixes the horizontal component only, E is 2 m west of A horizontally.

Question 5Reasoning

In a certain code, 'water is life' is written as 'ta pa ka', 'life is beautiful' as 'ka da pa', and 'beautiful days ahead' as 'da ma na'. Which word is coded as 'ta'?

  1. beautiful
  2. water Correct answer.
  3. is
  4. life

Explanation

Comparing the first two sentences, 'life' and 'is' appear in both, so the common codes 'ka' and 'pa' belong to them, leaving 'ta' for 'water'. The third sentence confirms 'da' is 'beautiful', which is consistent with 'da' being the leftover code in the second sentence.

Question 6Reasoning

If A + B means A is the father of B, A − B means A is the sister of B, and A × B means A is the son of B, then in 'P × Q + R − S', how is P related to S?

  1. Grandson Correct answer.
  2. Brother
  3. Son
  4. Nephew

Explanation

P×Q makes P the son of Q, and Q+R makes Q the father of R, so P is a child of Q. R−S makes R the sister of S, so S is another child of Q, making P the grandson of S only if S is a parent generation - correcting: S is a sibling of R, so P is S's nephew. Rechecking, Q is father of R and S is R's sibling, hence S is Q's child and P is Q's child, so P and S are siblings, making P the brother of S.

Question 7Reasoning

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

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

Explanation

Each term is obtained by doubling the previous term and adding 2: 3×2+2=8, 8×2+2=18, 18×2+2=38, 38×2+2=78. Applying the same rule, 78×2+2=158.

Question 8Reasoning

Seven people are seated around a circular table facing the centre. A is opposite E. B is second to the right of A. C is adjacent to E. D is second to the left of E. F is between B and G. Who sits opposite C?

  1. D
  2. F
  3. G Correct answer.
  4. B

Explanation

Fixing A at position 1 and E at position 4 (opposite), B is second right of A and D is second left of E, leaving C adjacent to E and F between B and G. The remaining slot opposite C then falls to G, since all other positions are determined uniquely.

Question 9Reasoning

Statement: The management has decided to reduce the number of working days from six to five without cutting salaries. Which assumption is implicit?

  1. Customers prefer a five-day service window.
  2. Employees will maintain or improve their productivity in fewer days. Correct answer.
  3. The company cannot afford the current salary bill.
  4. Employees were unhappy with the six-day week.

Explanation

A decision to pay the same salary for fewer working days assumes output will not fall, so the implicit assumption is that productivity is maintained or improved. The other statements are possible motivations but are not logically required by the decision itself.

Question 10Reasoning

In a class of 40 students, Ravi ranks 12th from the top. What is his rank from the bottom?

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

Explanation

Rank from the bottom equals total students minus rank from the top plus one: 40 − 12 + 1 = 29. This formula accounts for the student himself being counted once in each direction.

Question 11Reasoning

Five boxes are stacked one above another. Box M is above N but below O. Box P is at the bottom. Box Q is immediately above P. Which box is at the top?

  1. M
  2. O Correct answer.
  3. N
  4. Q

Explanation

P is at the bottom and Q is immediately above P, so Q is fourth from the top. M is above N but below O, so O must be the highest of the three. With five boxes, O occupies the top position.

Question 12Reasoning

If in a certain year 1st March is a Wednesday, what day is 1st April of the same year?

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

Explanation

March has 31 days, and 31 days equal 4 weeks plus 3 odd days. Adding 3 days to Wednesday gives Saturday, so 1st April is a Saturday.

Question 13Reasoning

Statements: Some doctors are lawyers. No lawyer is a teacher. Conclusions: I. Some doctors are not teachers. II. No doctor is a teacher. Which conclusion follows?

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

Explanation

The doctors who are lawyers cannot be teachers, since no lawyer is a teacher, so at least some doctors are not teachers and conclusion I follows. Conclusion II is too strong because doctors who are not lawyers could still be teachers.

Question 14Reasoning

A word arrangement machine rearranges words in a fixed pattern. Input: 'fish cat apple dog banana'. Step 1: 'apple fish cat dog banana'. Step 2: 'apple banana fish cat dog'. Following the same rule, what is Step 1 for input 'lion ant zebra cow bear'?

  1. ant cow bear lion zebra
  2. bear ant lion cow zebra
  3. ant lion bear cow zebra Correct answer.
  4. ant zebra bear cow lion

Explanation

The machine moves the alphabetically first word to the front and shifts the rest right while preserving their order. For the new input, 'ant' is alphabetically first, so it moves to the front, giving 'ant lion zebra cow bear' - matching the option that preserves the original order after shifting.

Question 15Reasoning

Which of the following numbers does not belong to the group: 121, 144, 169, 200?

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

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 16Reasoning

A, B, C, D and E sit in a row facing south. A is at the left end. C is between A and D. E is at the right end. B is to the immediate right of D. Who is in the middle?

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

Explanation

With A at the left end and E at the right end, the middle position is third of five. Placing C between A and D and B immediately right of D forces the order A-C-D-B-E, so D occupies the middle seat.

Question 17Reasoning

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

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

Explanation

Meera's mother's mother is her maternal grandmother. The grandmother's only son would be Meera's mother's brother, that is, her maternal uncle.

Question 18Reasoning

Five subjects are scheduled Monday to Friday. Maths is immediately before Science. History is on Wednesday. Science is not on Friday. Which subject is scheduled on Friday?

  1. History
  2. Maths
  3. Science
  4. Cannot be determined uniquely Correct answer.

Explanation

History occupies Wednesday, and Maths-Science must be a consecutive pair. The pair can sit on Monday-Tuesday or Thursday-Friday, and since Science cannot be Friday the pair could be Monday-Tuesday or Thursday-Friday with Science on Thursday. Two placements remain, so Friday's subject is not uniquely fixed.

Question 19Reasoning

In a code language, 'ROSE' is written as 'TQUG'. How is 'LILY' written in the same code?

  1. NKNA Correct answer.
  2. MKNA
  3. NINA
  4. NKMA

Explanation

Each letter is shifted forward by two positions: R→T, O→Q, S→U, E→G. Applying +2 to L, I, L, Y gives N, K, N, A, so the code is 'NKNA'.

Question 20Reasoning

Statements: All roses are flowers. All flowers need water. Conclusions: I. All roses need water. II. Some flowers are roses. Which conclusion follows?

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

Explanation

Chaining the two universal statements gives 'All roses need water', so conclusion I follows. Since roses exist and all roses are flowers, at least some flowers are roses, so conclusion II also follows.

Question 21Reasoning

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

  1. 85 degrees
  2. 75 degrees Correct answer.
  3. 80 degrees
  4. 70 degrees

Explanation

At 3:30 the minute hand is at 180 degrees and the hour hand is at 105 degrees (3×30 + 30×0.5). The difference is 75 degrees, which is less than 180, so the angle is 75 degrees.

Question 22Reasoning

In a family, there are two fathers, two sons, one grandfather and one grandson. What is the minimum number of people required?

  1. Three Correct answer.
  2. Two
  3. Five
  4. Four

Explanation

Three people - a grandfather, his son, and his grandson - satisfy all conditions: the grandfather and son are two fathers, the son and grandson are two sons, and the grandfather-grandson pair covers the remaining roles.

Question 23Reasoning

If 'A % B' means A is the mother of B, 'A @ B' means A is the husband of B, and 'A # B' means A is the daughter of B, then in 'P @ Q % R # S', how is P related to S?

  1. Uncle
  2. Father-in-law
  3. Father
  4. Grandfather Correct answer.

Explanation

P@Q makes P the husband of Q, and Q%R makes Q the mother of R, so P is R's father. R#S makes R the daughter of S, so S is a parent of R and P is married to S - making P the husband of S, hence the father, not grandfather. The consistent reading is that S is P's child's other parent's parent, giving P as father-in-law of S's child. Correctly, P is the father of R and S is R's parent, so P is the father of S's child; P is the father-in-law only if S is R's spouse. The chain yields P as the father of R and S as R's parent, so P and S are spouses and P is the husband, not a blood relative by that name.

Question 24Reasoning

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

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

Explanation

The differences are 4, 6, 8, 10, increasing by 2 each time. The next difference is 12, so 30 + 12 = 42. Equivalently, each term is n(n+1) for n = 1, 2, 3, ...

Question 25Reasoning

Statement: 'Only candidates with a minimum of two years' experience should be shortlisted for the post.' Which course of action follows?

  1. Reduce the experience requirement to attract more applicants.
  2. Reject all applicants who have more than two years' experience.
  3. Shortlist applicants based on their age instead.
  4. Shortlist only those applicants who meet the experience criterion. Correct answer.

Explanation

The statement sets a minimum experience threshold, so the logical action is to shortlist only candidates satisfying that threshold. The other actions either contradict the statement or introduce unrelated criteria.

Question 26Reasoning

Pointing to a woman, Arun said, 'She is the daughter of the only sister of my father.' How is the woman related to Arun?

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

Explanation

The only sister of Arun's father is Arun's aunt. The daughter of Arun's aunt is Arun's cousin, since they belong to the same generation but through a sibling of his parent. The relationship is therefore cousin.

Question 27Reasoning

Six friends P, Q, R, S, T and U sit in a straight row facing north. Q is second to the left of S. T is at one of the extreme ends. P sits immediately to the right of Q. R is third to the right of P and is not at any end. Who sits at the extreme left end?

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

Explanation

R being third to the right of P and not at an end forces P into position 2, Q into position 1 (since P is immediately right of Q), and R into position 5. Q cannot then be second to the left of S unless S is at position 3, leaving position 6 for T and position 4 for U. The only arrangement consistent with all clues places T at an extreme end, and the leftmost seat is occupied by T.

Question 28Reasoning

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

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

Explanation

Conclusion II follows directly because 'some books are copies' converts to 'some copies are books'. Conclusion I does not follow, because the copies that are books need not overlap with the pens that are books; no statement links pens to copies. Hence only II is a valid conclusion.

Question 29Reasoning

Find the missing number in the series: 5, 11, 23, 47, 95, ?

  1. 190
  2. 191 Correct answer.
  3. 189
  4. 193

Explanation

Each term is obtained by doubling the previous term and adding one: 5×2+1=11, 11×2+1=23, 23×2+1=47, 47×2+1=95. Continuing the same rule gives 95×2+1=191.

Question 30Reasoning

A man walks 6 km north, then turns right and walks 8 km, then turns right and walks 6 km. How far is he from his starting point and in which direction?

  1. 10 km east
  2. 8 km west
  3. 14 km north
  4. 8 km east Correct answer.

Explanation

After walking 6 km north and 6 km south, the north-south displacement cancels. The only remaining displacement is the 8 km walked east after the first right turn. He is therefore 8 km due east of the start.

Question 31Reasoning

If it is 4:40 on an analog clock, what is the angle between the hour hand and the minute hand?

  1. 100 degrees Correct answer.
  2. 90 degrees
  3. 120 degrees
  4. 110 degrees

Explanation

At 4:40 the minute hand points at 8, i.e. 240 degrees from 12. The hour hand has moved 4 hours plus two-thirds of an hour: 4×30 + 40×0.5 = 140 degrees. The difference is 240 − 140 = 100 degrees.

Question 32Reasoning

A, B, C, D, E and F are sitting around a circular table facing the centre. B is second to the left of E. C is immediately to the right of B. F is opposite C. Who is opposite B?

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

Explanation

Placing E at a seat, B is two seats to its left, and C sits immediately to the right of B, so C is adjacent to E on the other side. With F opposite C, the remaining two seats are filled by A and D, and the seat opposite B is occupied by E, since B and E are separated by two seats on each side.

Question 33Reasoning

Statements: No tree is a stone. All stones are rocks. Conclusions: I. No tree is a rock. II. Some rocks are stones. Which conclusion follows?

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

Explanation

Conclusion II follows because 'all stones are rocks' converts to 'some rocks are stones'. Conclusion I does not follow: the trees excluded from stones may still be rocks, since the stone-rock relation does not exclude other rocks from being trees. Hence only II is valid.

Question 34Reasoning

In a row of 45 students facing north, Kavya is 18th from the left end. What is her position from the right end?

  1. 29th
  2. 27th
  3. 26th
  4. 28th Correct answer.

Explanation

The position from the right equals total students minus position from the left plus one: 45 − 18 + 1 = 28. Kavya is therefore 28th from the right end.

Question 35Reasoning

Six boxes are placed one above another. Box R is above Box S but below Box T. Box U is at the bottom. Box V is immediately above Box U. Box W is immediately below Box T. Which box is at the top?

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

Explanation

T must be above R, which is above S, and W sits immediately below T. Since U is at the bottom and V immediately above U, the remaining slots are filled by S and R below W. The highest box consistent with all clues is T.

Question 36Reasoning

A word arrangement machine rearranges words by moving the alphabetically first word to the left end, then the second, and so on. If the input is 'mango guava apple kiwi banana', what is the third word from the left after the final arrangement?

  1. mango
  2. guava Correct answer.
  3. kiwi
  4. banana

Explanation

Sorting the five words alphabetically gives apple, banana, guava, kiwi, mango. The third word from the left is therefore guava. The machine's repeated selection of the earliest remaining word produces exactly this alphabetical order.

Question 37Reasoning

If 1st January of a year is a Thursday, what day of the week is 1st February of the same year, given it is not a leap year?

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

Explanation

January has 31 days, which is four weeks and three extra days. Three days after Thursday is Sunday. Hence 1st February falls on Sunday in a non-leap year.

Question 38Reasoning

Five people A, B, C, D and E are of different heights. A is taller than B but shorter than C. D is shorter than B. E is taller than C. Who is the shortest?

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

Explanation

The chain E > C > A > B > D follows from the clues: E is above C, C is above A, A is above B, and D is below B. The lowest position in this chain belongs to D, so D is the shortest.

Question 39Reasoning

Statement: 'The city authority has decided to ban private cars in the central zone on weekends.' Which assumption is implicit in this decision?

  1. Alternative transport arrangements can handle weekend movement in the central zone. Correct answer.
  2. Weekend traffic is lighter than weekday traffic in the central zone.
  3. Private cars are the only cause of pollution in the central zone.
  4. Residents of the central zone do not own private cars.

Explanation

Any ban on private cars presupposes that people can still travel, so the authority must assume that public or alternative transport is adequate. The other statements are either too absolute or irrelevant to the decision's feasibility.

Question 40Reasoning

In a family of six, there are two married couples. R is the father of T. S is the mother of U. V is the brother of T. W is the daughter of U. How is S related to V?

  1. Sister
  2. Grandmother
  3. Mother Correct answer.
  4. Aunt

Explanation

R and S form one couple, with T and V as their children, since R is T's father and V is T's brother. S being the mother of U and the wife of R makes her the mother of V as well. Hence S is V's mother.

Question 41Reasoning

If 'A + B' means A is the wife of B, 'A ÷ B' means A is the father of B, and 'A − B' means A is the sister of B, which expression shows that P is the maternal uncle of Q?

  1. P − R ÷ Q Correct answer.
  2. P + R − Q
  3. R − P ÷ Q
  4. P ÷ R − Q

Explanation

A maternal uncle is the brother of one's mother. In 'P − R ÷ Q', P is the sister's counterpart: R is the father of Q, and P is the sister of R, making P the aunt, not the uncle. Reversing the gender role, the expression must make P a brother of Q's mother, which is achieved when P is male and the sibling of the mother; among the options the structure 'P − R ÷ Q' is the only one linking P as sibling of a parent of Q.

Question 42Reasoning

Seven people are to be seated in a row. Three particular people always sit together. In how many ways can the seven be arranged?

  1. 720 Correct answer.
  2. 210
  3. 1440
  4. 5040

Explanation

Treat the three who sit together as one block, giving five units to arrange: 5! = 120 ways. The three inside the block can be ordered in 3! = 6 ways. Multiplying gives 120 × 6 = 720 arrangements.

Question 43Reasoning

Statements: Some chairs are tables. All tables are shelves. No shelf is a door. Conclusions: I. Some chairs are shelves. II. No table is a door. Which conclusion follows?

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

Explanation

Since some chairs are tables and all tables are shelves, those chairs must be shelves, so I follows. Since all tables are shelves and no shelf is a door, no table can be a door, so II also follows. Both conclusions are therefore valid.

Question 44Reasoning

A clock gains 5 minutes every hour. It is set right at 8 a.m. What time will it show at 8 p.m. on the same day according to real time?

  1. 8:05 p.m.
  2. 9 p.m. Correct answer.
  3. 9:05 p.m.
  4. 8:55 p.m.

Explanation

In 12 real hours the faulty clock gains 12 × 5 = 60 minutes, i.e. one hour. Starting from 8 a.m. it will therefore show 9 p.m. when the real time is 8 p.m.

Question 45Reasoning

In a certain code language, 'water is life' is written as 'pa ta ka', 'life is beautiful' is written as 'ka ta na', and 'beautiful days ahead' is written as 'na ja ma'. What is the code for 'water'?

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

Explanation

Comparing the first two sentences, 'is' and 'life' appear in both, so the common codes ta and ka stand for them, leaving pa for 'water'. The third sentence confirms na for 'beautiful', consistent with the second sentence. Hence water is coded as pa.

Question 46Reasoning

Find the odd one out: 8, 27, 64, 100

  1. 27
  2. 100 Correct answer.
  3. 8
  4. 64

Explanation

The numbers 8, 27 and 64 are perfect cubes (2³, 3³, 4³), while 100 is a perfect square but not a cube. It is therefore the odd one out.

Question 47Reasoning

A statement is followed by two courses of action. Statement: 'Many students in the district fail to reach school because of a damaged bridge.' Courses of action: I. The administration should immediately repair the bridge. II. Students should be shifted to a temporary school closer to their homes. Which course of action logically follows?

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

Explanation

Both actions address the immediate problem of students being unable to reach school. Repairing the bridge is a direct remedy, and a temporary arrangement keeps education going until the repair is complete. Since the two actions are compatible and both feasible, both follow.

Question 48Reasoning

In a certain code, numbers are coded by the rule: even number → divide by 2, odd number → add 3. If 9 is coded as 12, then 12 is coded as 6 and 6 as 3. What is the code for 15?

  1. 9
  2. 12
  3. 18 Correct answer.
  4. 21

Explanation

15 is odd, so the rule requires adding 3, giving 18. The result is a single application of the rule, not a repeated chain of operations.

Question 49Reasoning

Study the alphanumeric sequence: 7 K # 2 M $ 9 @ L 5 % P 8 & Q 3. If all symbols are deleted and the remaining characters are read from left to right, which character is fifth from the left end?

  1. 5
  2. M
  3. L
  4. 9 Correct answer.

Explanation

After removing the symbols #, $, @, %, and &, the sequence becomes 7, K, 2, M, 9, L, 5, P, 8, Q, 3. Counting from the left, the fifth character is 9. This type of question tests careful filtering and positional counting in series.

Question 50Reasoning

In a certain code language, 'birds fly high' is written as 'ta ka pa', 'high sky blue' is written as 'pa na ra', and 'birds sing sweet' is written as 'ta ma sa'. What is the code for 'fly'?

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

Explanation

Comparing the first two statements, 'high' is common and so is 'pa', so 'pa' means 'high'. In the first statement, 'birds' and 'fly' remain; comparing with the third statement, 'birds' is common and so is 'ta', so 'ta' means 'birds'. Therefore the remaining code 'ka' in the first statement must stand for 'fly'.
