1
Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
EFG, HIJ, KLM, ?
A.NOP
B.GHS
C.BHS
D.KMN
Solution
Consecutive letters
Each cluster has three consecutive letters.
The first letters go E, H, K — each +3 ⇒ next is N.
So the cluster is N, O, P.
Hence NOP — option (a).
2
Choose the address that is the same as the one given below.
Bungalow 10, Marine Drive, Mumbai, Maharashtra - 500080
Address matching
Everything except the PIN code is identical in all four options.
The given PIN is 500080.
(a) shows 501080, (b) 500012 and (d) 500021.
Only (c) matches — option (c).
3
Choose the address that is the same as the one given below.
Sample Address: House No. 87, Block C, Karol Bagh, New Delhi, Delhi - 110056
A.House No. 87, Block-C, Karol Bagh, New Delhi, Delhi - 110056
B.House No. 87, Block C, Karol Bagh, New Delhi, Delhi - 110056
C.House 87, Block C, Karol Bagh, New Delhi, Delhi - 110056
D.House No. 87, Block D, Karol Bagh, New Delhi, Delhi - 110056
Solution
Address matching
(a) adds a hyphen in 'Block-C'; (c) drops 'No.'.
(d) changes the block to D.
Only (b) matches the sample exactly.
Hence option (b).
4
Consider the following statement and choose the option that follows.Statement: Many accidents occur due to careless driving at night.
Conclusions:
I. Night driving should be banned.
II. Drivers should be educated about safe driving.
A.Only I follows
B.Only II follows
C.Both follow
D.Neither follows
Solution
Statement — conclusions
The problem is CARELESS driving, not night driving itself.
Educating drivers attacks the real cause — II follows.
Banning night driving is extreme and would paralyse normal life — I does not follow.
Hence Only II — option (b).
5
Consider the following statement and choose the option that follows.
Problem: City roads are full of potholes, leading to frequent traffic jams.
Course of Action:
I. The municipal corporation should repair the roads immediately.
II. People should avoid using vehicles.
A.Only I follows
B.Only II follows
C.Both follow
D.Neither follows
Solution
Course of action
The potholes are the cause, so repairing the roads removes the problem — I follows.
Asking people to stop using vehicles is impractical and does not fix the roads.
A course of action must be workable.
Hence Only I — option (a).
6
A number is increased by 10% and then decreased by 10%. What is the net change in the number?
A.4% increase
B.4% decrease
C.No change
D.1% decrease
Solution
Successive % change
Net change = a + b + with a = +10 and b = −10.
= 10 − 10 − .
= −1.
So a 1% decrease — option (d).
7
If '×' stands for addition, '÷' stands for subtraction, '+' stands for multiplication, and '−' stands for division, then 14 × 6 ÷ 6 − 3 + 4 = ?
If 'A' denotes addition, 'B' denotes subtraction, 'C' denotes multiplication, and 'D' denotes division, then what will be the value of the following expression?
{20 B (25 B 33)} D {−5 C 4 B (−6)} A 56 D (−27 A 13)
A.−6
B.6
C.4
D.−4
Solution
Coded operations
Replace the letters: {20 − (25 − 33)} ÷ {−5 × 4 − (−6)} + 56 ÷ (−27 + 13).
First brackets: 20 − (−8) = 28 and −20 + 6 = −14; the last bracket is −14.
28 ÷ (−14) = −2 and 56 ÷ (−14) = −4.
−2 + (−4) = −6 — option (a).
9
If "+" means division, "−" means multiplication, "×" means addition, and "÷" means subtraction, then what is 48 − 9 + 6 ÷ 4 × 8 = ?
P is the father of Q. Q is the husband of R. S is the daughter of R. How is P related to S?
A.Father
B.Grandfather
C.Uncle
D.Brother
Solution
Blood relation
Q and R are husband and wife, and S is their daughter.
P is Q’s father, i.e. one generation above Q.
So P is two generations above S.
P is S’s grandfather — option (b).
11
Solve: FLOW : WOLF :: FORT : ?
A.TROF
B.TPOS
C.PSOT
D.TSOP
Solution
Word reversal
FLOW written backwards gives WOLF.
Reverse FORT letter by letter: T, R, O, F.
That is TROF.
Hence option (a).
12
Complete the given pattern: 17, 23, 31, 41, 53, ?
A.47
B.67
C.59
D.61
Solution
Series — even gaps
Differences: 6, 8, 10, 12 — each rises by 2.
So the next difference is 14.
53 + 14 = 67.
Hence option (b).
13
Read the following statement carefully and identify the conclusion that follows.Statement: The bank introduced online appointment booking for branch visits.
Conclusions:
I. The bank wants to reduce crowding in branches.
II. Customers will stop visiting branches.
A.Only Conclusion I follows
B.Only Conclusion II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Statement — conclusions
Appointment booking spreads visits over the day, so crowding falls — I follows.
Customers will still come for essential work; II is an extreme claim.
Booking manages visits, it does not end them.
Hence option (a).
14
Read the following statement carefully and identify the conclusion that follows.Statement: The railway department has increased the number of ticket counters at major stations.
Conclusions:
I. The department wants to reduce passenger queues.
II. The number of passengers has increased.
A.Only Conclusion I follows
B.Only Conclusion II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Statement — conclusions
More counters obviously aim to cut waiting queues — I follows.
Counters are added when demand grows, so a rise in passengers is a fair inference — II also follows.
Both are natural explanations of the step.
Hence Both — option (c).
15
If GANGA is coded as 711471, how will KAVERI be coded?
A.261131421
B.261131425
C.261113421
D.111225189
Solution
Letter place values
Each letter is replaced by its position: G = 7, A = 1, N = 14, G = 7, A = 1 → 7-1-14-7-1 = 711471 ✓.
KAVERI: K = 11, A = 1, V = 22, E = 5, R = 18, I = 9.
Writing them together: 11-1-22-5-18-9.
= 111225189 — option (d).
16
What comes next?
BYB, CXC, DWD, EVE, ?
A.EVE
B.FUF
C.EUE
D.EXE
Solution
Letter series (+1, −1, +1)
1st and 3rd letters are the same and move +1: B, C, D, E → F.
2nd letters: Y, X, W, V — each −1 ⇒ next is U.
So the cluster is F, U, F.
Hence FUF — option (b).
17
Find the odd one out from the given alternatives:
A.Square
B.Triangle
C.Circle
D.Rectangle
Solution
Polygons vs circle
Square, triangle and rectangle are POLYGONS made of straight sides.
A circle has no sides — it is a single curved line.
So it belongs to a different category.
Hence option (c).
18
If 'JUMP' is coded as 'KVNQ', what is the code for 'QMTP'?
A.RNVQ
B.RNWQ
C.RNXQ
D.RNUQ
Solution
Coding (+1)
J+1 = K, U+1 = V, M+1 = N, P+1 = Q — every letter moves +1.
Apply to QMTP: Q+1 = R, M+1 = N.
T+1 = U, P+1 = Q.
Hence RNUQ — option (d).
19
What will come at the place of the question mark?
5 7 12 | 4 9 13 | 6 8 ?
A.14
B.18
C.17
D.15
Solution
Sum of two digits
Rule: first number + second number = third number.
Check: 5 + 7 = 12 ✓ and 4 + 9 = 13 ✓.
So 6 + 8.
= 14 — option (a).
20
If the given symbols mean: '+' means 'divided by', '−' means 'multiplied by', '×' means 'minus', '÷' means 'plus', then find the value of the following expression:
18 + 3 − 8 × 2 ÷ 1 = ?
P says to Q, "I am the daughter of the only son of your father." How is Q related to P?
A.Grandfather
B.Father
C.Uncle
D.Brother
Solution
Blood relation
The only son of Q's father is Q himself (Q must be male).
P is the daughter of that only son.
So P is Q’s daughter, which makes Q her father.
Hence option (b).
22
If '×' = '−', '−' = '+', '/' = '×', and '+' = '÷', which equation is correct?
A.60 − 4 + 8 / 2 × 1 = 60
B.18 − 6 × 3 + 2 / 2 = 13
C.14 + 7 − 3 / 2 × 1 = 16
D.12 × 4 − 2 + 8 / 4 = 11
Solution
Symbol substitution
Test option (a): 60 − 4 + 8 / 2 × 1 becomes 60 + 4 ÷ 8 × 2 − 1.
BODMAS: 4 ÷ 8 = 0.5, then 0.5 × 2 = 1.
60 + 1 − 1 = 60 = RHS ✓ (the other options do not balance).
Hence option (a).
23
If '×' means '+', '+' means '−', and '−' means '÷', then 5 × 6 + 4 − 2 = ?
What should come at the place of the question mark?
2, 6, 18, 54, ?
A.108
B.162
C.216
D.324
Solution
Series (×3)
Each term is three times the previous one.
2×3 = 6, 6×3 = 18, 18×3 = 54 ✓.
Next: 54 × 3.
= 162 — option (b).
25
The series given below contains a sequence of numbers. Accordingly identify the incorrect combination.
10, 13, 26, 29, 59, 61, 121
A.13, 29
B.26, 61
C.59, 121
D.10, 26
Solution
Wrong terms in series
The rule alternates +3 and ×2: 10, 13, 26, 29, 58, 61, 122.
The series shows 59 in place of 58 and 121 in place of 122.
Every other term follows the pattern.
So 59 and 121 are the incorrect terms — option (c).
Finished reading? Now test yourself.
The same 25 questions, but with a timer and the answers hidden — 15 minutes.
Each cluster has three consecutive letters.
The first letters go E, H, K — each +3 ⇒ next is N.
So the cluster is N, O, P.
Hence NOP — option (a).
Net change = a + b + with a = +10 and b = −10.
= 10 − 10 − .
= −1.
So a 1% decrease — option (d).
Replace the symbols: 14 × 6 ÷ 6 − 3 + 4 becomes 14 + 6 − 6 ÷ 3 × 4.
BODMAS: 6 ÷ 3 = 2, then 2 × 4 = 8.
14 + 6 − 8.
= 12 — option (a).
Replace the letters: {20 − (25 − 33)} ÷ {−5 × 4 − (−6)} + 56 ÷ (−27 + 13).
First brackets: 20 − (−8) = 28 and −20 + 6 = −14; the last bracket is −14.
28 ÷ (−14) = −2 and 56 ÷ (−14) = −4.
−2 + (−4) = −6 — option (a).
Replace the symbols: 48 × 9 ÷ 6 − 4 + 8.
BODMAS: 48 × 9 = 432, then 432 ÷ 6 = 72.
72 − 4 + 8.
= 76 — option (b).
Q and R are husband and wife, and S is their daughter.
P is Q’s father, i.e. one generation above Q.
So P is two generations above S.
P is S’s grandfather — option (b).
FLOW written backwards gives WOLF.
Reverse FORT letter by letter: T, R, O, F.
That is TROF.
Hence option (a).
Differences: 6, 8, 10, 12 — each rises by 2.
So the next difference is 14.
53 + 14 = 67.
Hence option (b).
Each letter is replaced by its position: G = 7, A = 1, N = 14, G = 7, A = 1 → 7-1-14-7-1 = 711471 ✓.
KAVERI: K = 11, A = 1, V = 22, E = 5, R = 18, I = 9.
Writing them together: 11-1-22-5-18-9.
= 111225189 — option (d).
1st and 3rd letters are the same and move +1: B, C, D, E → F.
2nd letters: Y, X, W, V — each −1 ⇒ next is U.
So the cluster is F, U, F.
Hence FUF — option (b).
J+1 = K, U+1 = V, M+1 = N, P+1 = Q — every letter moves +1.
Apply to QMTP: Q+1 = R, M+1 = N.
T+1 = U, P+1 = Q.
Hence RNUQ — option (d).
Rule: first number + second number = third number.
Check: 5 + 7 = 12 ✓ and 4 + 9 = 13 ✓.
So 6 + 8.
= 14 — option (a).
Replace the symbols: 18 ÷ 3 × 8 − 2 + 1.
BODMAS: 18 ÷ 3 = 6, then 6 × 8 = 48.
48 − 2 + 1.
= 47 — option (b).
The only son of Q's father is Q himself (Q must be male).
P is the daughter of that only son.
So P is Q’s daughter, which makes Q her father.
Hence option (b).
Test option (a): 60 − 4 + 8 / 2 × 1 becomes 60 + 4 ÷ 8 × 2 − 1.
BODMAS: 4 ÷ 8 = 0.5, then 0.5 × 2 = 1.
60 + 1 − 1 = 60 = RHS ✓ (the other options do not balance).
Hence option (a).
Replace the symbols: 5 + 6 − 4 ÷ 2.
BODMAS: 4 ÷ 2 = 2.
5 + 6 − 2 = 11 − 2.
= 9 — option (c).
Each term is three times the previous one.
2×3 = 6, 6×3 = 18, 18×3 = 54 ✓.
Next: 54 × 3.
= 162 — option (b).
The rule alternates +3 and ×2: 10, 13, 26, 29, 58, 61, 122.
The series shows 59 in place of 58 and 121 in place of 122.
Every other term follows the pattern.
So 59 and 121 are the incorrect terms — option (c).
