Consider the following statement and choose the option that follows.Statement: The government has launched a free skill-development programme for unemployed youth.
Conclusions:
I. More young people will gain employment opportunities.
II. The unemployment rate will immediately drop drastically.
A.Only I follows
B.Only II follows
C.Both follow
D.Neither follows
Solution
Conclusions
Skill training does reasonably help young people find work — I follows.
II claims the rate will fall IMMEDIATELY and DRASTICALLY.
Nothing in the statement supports so sudden and sweeping a change; training takes time to show results ✗.
Only I — option (a).
4
If 8 − 3 = 15 and 9 − 2 = 21, then 7 − 3 = ?
A.10
B.12
C.9
D.13
Solution
(a − b) × 3
Rule: (first number − second number) × 3.
Check: (8 − 3) × 3 = 15 ✓ and (9 − 2) × 3 = 21 ✓.
(7 − 3) × 3 = 4 × 3.
= 12 — option (b).
5
What should come in place of the question mark '?' in the following number series?
4, 6, 9, 13.5, ?, 30.375
A.20
B.25.2
C.20.25
D.22
Solution
Series (×1.5)
Each term is 1.5 times the previous one.
4 × 1.5 = 6, 6 × 1.5 = 9, 9 × 1.5 = 13.5 ✓.
13.5 × 1.5 = 20.25, and 20.25 × 1.5 = 30.375 ✓.
= 20.25 — option (c).
6
If 6 → 12, 5 → 10 and 4 → 8, then 12 → ?
A.20
B.22
C.24
D.26
Solution
Double the number
Rule: the number is doubled.
Check: 6 × 2 = 12 ✓, 5 × 2 = 10 ✓ and 4 × 2 = 8 ✓.
12 × 2.
= 24 — option (c).
7
If TRAIN = 62 and PANT = 51, then what is the value of CAT?
A.32
B.24
C.41
D.22
Solution
Sum of place values
Each letter is replaced by its place in the alphabet and the values are added.
TRAIN = 20 + 18 + 1 + 9 + 14 = 62 ✓ and PANT = 16 + 1 + 14 + 20 = 51 ✓.
CAT = 3 + 1 + 20.
= 24 — option (b).
8
The given statements are followed by two conclusions. Find out which conclusion is FALSE based on the given statements.Statements: S > K = L; M ≥ N < K; O < S < U; N = Q ≥ T
Conclusions:
I. U > L
II. K ≥ T
A.Only conclusion I is false
B.Only conclusion II is false
C.Both conclusion I and II are false
D.Neither conclusion I nor II is false
Solution
Coded inequality
For I: L = K < S < U, so the chain runs one way and U > L is TRUE ✓.
For II: T ≤ Q = N < K, which gives K > T, and that also satisfies K ≥ T — TRUE ✓.
Since both conclusions hold, neither of them is false.
Hence option (d).
9
Which city is different from the rest?
A.Lucknow
B.Jaipur
C.Pune
D.Patna
Solution
State capitals
Lucknow, Jaipur and Patna are the capitals of Uttar Pradesh, Rajasthan and Bihar.
Pune is not a capital — Mumbai is the capital of Maharashtra.
So it stands apart from the rest.
Hence option (c).
10
Select the set of numbers that is NOT similar to the following set:
(11, 65, 87)
A.(7, 35, 49)
B.(8, 42, 58)
C.(5, 28, 40)
D.(14, 55, 83)
Solution
Number-set pattern
Rule: (first number × 2) + second number = third number.
Check the given set: 11 × 2 + 65 = 22 + 65 = 87 ✓.
(7, 35, 49): 14 + 35 = 49 ✓; (8, 42, 58): 16 + 42 = 58 ✓; (14, 55, 83): 28 + 55 = 83 ✓.
(5, 28, 40): 10 + 28 = 38, not 40 ✗ — option (c).
11
P is the sister of Q. R is the father of P. How is R related to Q?
A.Uncle
B.Father
C.Grandfather
D.Brother
Solution
Blood relation
P and Q are sister and sibling, so they share the same parents.
R is P’s father.
So R must be Q’s father as well.
Hence option (b).
12
A sum of money triples in 15 years under simple interest. In how many years will it become 9 times?
A.60
B.50
C.30
D.40
Solution
Simple interest multiples
Tripling means the interest earned equals 2 times the principal in 15 years.
So 1 times the principal is earned in = 7.5 years.
To become 9 times, the interest must be 8 times the principal.
8 × 7.5 = 60 years — option (a).
Study the following information carefully and answer the question.
Seven boxes of different colours — Blue, Yellow, Maroon, Violet, Brown, Cyan and Teal — are kept one above the other, not necessarily in that order. The topmost box is numbered 7 and the bottommost 1.
The number of boxes below the brown box equals the number above it. The yellow box is not at the bottom. Two boxes lie between the maroon and brown boxes. The teal box is above the brown box but below the violet box. The blue and cyan boxes are neither at the top nor at the bottom. The blue box is immediately below the cyan box. The violet box is not at the top.
Four of them are alike in a certain way; find the ODD one among the following options.
A.Maroon
B.Brown
C.Yellow
D.Teal
Solution
Box arrangement
Brown has equal numbers above and below, so brown is on floor 4. Maroon is two boxes away, and with the rest of the clues maroon takes floor 1.
Teal lies above brown and below violet, and the blue-cyan pair sits together in the middle, giving blue 2, cyan 3, teal 5, violet 6 and yellow 7.
So the order from the bottom is Maroon, Blue, Cyan, Brown, Teal, Violet, Yellow.
Maroon(1), Cyan(3), Teal(5) and Yellow(7) are all on ODD floors; brown alone is on an even floor — option (b).
15
Read the following statement carefully and identify the assumptions that follow.Statement: The city traffic police have decided to deploy additional patrol units to reduce rash driving.
Assumptions:
I. Increased patrolling will discourage rash driving.
II. Drivers change their behaviour when they see police presence.
A.Only Assumption I is implicit
B.Only Assumption II is implicit
C.Both I and II are implicit
D.Neither I nor II is implicit
Solution
Assumptions
The police would not add patrols unless they expected patrolling to reduce rash driving — I is implicit.
That expectation itself rests on drivers behaving better when they see the police — II is implicit.
The second assumption is the reason the first is believed to work.
Both — option (c).
16
What is the next number in the series?
625, 125, 25, 5, ?
A.0
B.1
C.5
D.25
Solution
Series (÷5)
Each term is the previous one divided by 5.
625 ÷ 5 = 125, 125 ÷ 5 = 25, 25 ÷ 5 = 5 ✓.
5 ÷ 5.
= 1 — option (b).
17
What comes next in the series?
E, I, M, Q, U, ?
A.Z
B.Y
C.V
D.T
Solution
Letter series (+4)
Each letter moves four places forward.
E(5) → I(9) → M(13) → Q(17) → U(21) ✓.
21 + 4 = 25.
The 25th letter is Y — option (b).
18
What comes next?
CD, DE, EF, FG, GH, ?
A.HJ
B.FG
C.HI
D.FE
Solution
Letter pairs (+1)
Each pair holds two consecutive letters, and each pair starts one letter after the last.
CD, DE, EF, FG, GH ✓.
The next pair must begin with H.
= HI — option (c).
19
In a certain code, SWEET becomes TXFFU. How is LIGHT written?
A.MJIHU
B.MJHIU
C.MIJUH
D.MJHUI
Solution
Coding (+1)
Every letter moves one place forward: S+1 = T, W+1 = X, E+1 = F, E+1 = F, T+1 = U ✓.
Apply to LIGHT: L+1 = M, I+1 = J, G+1 = H.
H+1 = I, T+1 = U.
Hence MJHIU — option (b).
20
Which interchange of numbers and signs will make the equation correct?
9 × 3 + 5 = 32
A.+ and ×, 3 and 5
B.+ and ×, 9 and 3
C.+ and ×, 5 and 9
D.+ and ×, 9 and 32
Solution
Interchange signs and digits
Swap + with × and 5 with 9: the equation becomes 5 + 3 × 9.
BODMAS: 3 × 9 = 27.
5 + 27.
= 32 ✓ — option (c).
21
If ICMOAD is coded as KAOMCB, how is GRESLY coded?
A.GBNJMZ
B.HCONLA
C.IPGQNW
D.HCONMZ
Solution
Odd +2, even −2
Compare ICMOAD with KAOMCB position by position: I+2 = K, C−2 = A, M+2 = O, O−2 = M, A+2 = C, D−2 = B.
So the odd positions move +2 and the even positions −2.
Apply to GRESLY: G+2 = I, R−2 = P, E+2 = G, S−2 = Q, L+2 = N, Y−2 = W.
Hence IPGQNW — option (c).
22
Select the letter-cluster that can replace the question mark (?) in the following series:
HIVX, JMYA, LQBD, NUEG, ?
A.ZBCX
B.QCTR
C.PYSB
D.PYHJ
Solution
Letter-cluster series
1st letters: H, J, L, N — each +2 ⇒ next is P.
2nd letters: I, M, Q, U — each +4 ⇒ next is Y.
3rd letters: V, Y, B, E — each +3 ⇒ next is H; 4th letters: X, A, D, G — each +3 ⇒ next is J.
Hence PYHJ — option (d).
23
Read the following statements carefully and identify the conclusion that follows.Statements:
All trees are living beings.
Some living beings are humans.
Conclusions:
I. Some trees are humans.
II. All humans are trees.
A.Only I follows
B.Only II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Syllogism
Trees lie inside living beings, but only SOME living beings are humans.
Those humans need not be among the trees, so I is not certain ✗.
"Some living beings are humans" can never give "all humans are trees" — II is false ✗.
Neither follows — option (d).
24
A person's age is 5 times that of his son. After 6 years, the person's age will be 3 times his son's. What is the son's age now?
A.5 years
B.6 years
C.8 years
D.10 years
Solution
Ages
Let the son be x years, so the father is 5x.
After 6 years: 5x + 6 = 3(x + 6).
5x + 6 = 3x + 18 ⇒ 2x = 12.
x = 6 years — option (b).
25
If the sum of 34 and 22 is multiplied by 2, what is the result?
A.110
B.108
C.112
D.100
Solution
Simple arithmetic
First find the sum: 34 + 22 = 56.
Then multiply by 2.
56 × 2.
= 112 — option (c).

Lucknow’s seminar was on 12 February.
Vadodara’s was on 16 February.
16 − 12.
= 4 days later — option (a).
Rule: (first number − second number) × 3.
Check: (8 − 3) × 3 = 15 ✓ and (9 − 2) × 3 = 21 ✓.
(7 − 3) × 3 = 4 × 3.
= 12 — option (b).
Each term is 1.5 times the previous one.
4 × 1.5 = 6, 6 × 1.5 = 9, 9 × 1.5 = 13.5 ✓.
13.5 × 1.5 = 20.25, and 20.25 × 1.5 = 30.375 ✓.
= 20.25 — option (c).
Rule: the number is doubled.
Check: 6 × 2 = 12 ✓, 5 × 2 = 10 ✓ and 4 × 2 = 8 ✓.
12 × 2.
= 24 — option (c).
Each letter is replaced by its place in the alphabet and the values are added.
TRAIN = 20 + 18 + 1 + 9 + 14 = 62 ✓ and PANT = 16 + 1 + 14 + 20 = 51 ✓.
CAT = 3 + 1 + 20.
= 24 — option (b).
For I: L = K < S < U, so the chain runs one way and U > L is TRUE ✓.
For II: T ≤ Q = N < K, which gives K > T, and that also satisfies K ≥ T — TRUE ✓.
Since both conclusions hold, neither of them is false.
Hence option (d).
Lucknow, Jaipur and Patna are the capitals of Uttar Pradesh, Rajasthan and Bihar.
Pune is not a capital — Mumbai is the capital of Maharashtra.
So it stands apart from the rest.
Hence option (c).
Rule: (first number × 2) + second number = third number.
Check the given set: 11 × 2 + 65 = 22 + 65 = 87 ✓.
(7, 35, 49): 14 + 35 = 49 ✓; (8, 42, 58): 16 + 42 = 58 ✓; (14, 55, 83): 28 + 55 = 83 ✓.
(5, 28, 40): 10 + 28 = 38, not 40 ✗ — option (c).
P and Q are sister and sibling, so they share the same parents.
R is P’s father.
So R must be Q’s father as well.
Hence option (b).
Tripling means the interest earned equals 2 times the principal in 15 years.
So 1 times the principal is earned in = 7.5 years.
To become 9 times, the interest must be 8 times the principal.
8 × 7.5 = 60 years — option (a).
Rule: cube the number and subtract 1.
Check: 6³ − 1 = 216 − 1 = 215 ✓.
8³ − 1 = 512 − 1.
= 511 — option (a).
Brown has equal numbers above and below, so brown is on floor 4. Maroon is two boxes away, and with the rest of the clues maroon takes floor 1.
Teal lies above brown and below violet, and the blue-cyan pair sits together in the middle, giving blue 2, cyan 3, teal 5, violet 6 and yellow 7.
So the order from the bottom is Maroon, Blue, Cyan, Brown, Teal, Violet, Yellow.
Maroon(1), Cyan(3), Teal(5) and Yellow(7) are all on ODD floors; brown alone is on an even floor — option (b).
Each term is the previous one divided by 5.
625 ÷ 5 = 125, 125 ÷ 5 = 25, 25 ÷ 5 = 5 ✓.
5 ÷ 5.
= 1 — option (b).
Each letter moves four places forward.
E(5) → I(9) → M(13) → Q(17) → U(21) ✓.
21 + 4 = 25.
The 25th letter is Y — option (b).
Each pair holds two consecutive letters, and each pair starts one letter after the last.
CD, DE, EF, FG, GH ✓.
The next pair must begin with H.
= HI — option (c).
Every letter moves one place forward: S+1 = T, W+1 = X, E+1 = F, E+1 = F, T+1 = U ✓.
Apply to LIGHT: L+1 = M, I+1 = J, G+1 = H.
H+1 = I, T+1 = U.
Hence MJHIU — option (b).
Swap + with × and 5 with 9: the equation becomes 5 + 3 × 9.
BODMAS: 3 × 9 = 27.
5 + 27.
= 32 ✓ — option (c).
Compare ICMOAD with KAOMCB position by position: I+2 = K, C−2 = A, M+2 = O, O−2 = M, A+2 = C, D−2 = B.
So the odd positions move +2 and the even positions −2.
Apply to GRESLY: G+2 = I, R−2 = P, E+2 = G, S−2 = Q, L+2 = N, Y−2 = W.
Hence IPGQNW — option (c).
1st letters: H, J, L, N — each +2 ⇒ next is P.
2nd letters: I, M, Q, U — each +4 ⇒ next is Y.
3rd letters: V, Y, B, E — each +3 ⇒ next is H; 4th letters: X, A, D, G — each +3 ⇒ next is J.
Hence PYHJ — option (d).
Trees lie inside living beings, but only SOME living beings are humans.
Those humans need not be among the trees, so I is not certain ✗.
"Some living beings are humans" can never give "all humans are trees" — II is false ✗.
Neither follows — option (d).
Let the son be x years, so the father is 5x.
After 6 years: 5x + 6 = 3(x + 6).
5x + 6 = 3x + 18 ⇒ 2x = 12.
x = 6 years — option (b).
First find the sum: 34 + 22 = 56.
Then multiply by 2.
56 × 2.
= 112 — option (c).
