Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
PQR, MNO, JKL, GHI, ?
A.ADS
B.DGF
C.DEF
D.AHB
Solution
Letter series (−3)
Each cluster has three consecutive letters and every cluster moves back by 3.
P, M, J, G → next first letter is D.
So the cluster is D, E, F.
Hence DEF — option (c).
2
Choose the address that is the same as the one given below.
20, Rani Ghat Road, Jaipur, Rajasthan - 302001
A.20, Raj Ghat Road, Jaipur, Rajasthan - 302001
B.20, Rani Ghat Road, Jaipur, Rajasthan - 302002
C.20, Rani Ghat Road, Jaipur, Rajasthan - 302001
D.21, Rani Ghat Road, Jaipur, Rajasthan - 302001
Solution
Address matching
(a) writes 'Raj Ghat' instead of 'Rani Ghat'.
(b) changes the PIN to 302002 and (d) the house number to 21.
Only (c) matches every detail.
Hence option (c).
3
Choose the address that is the same as the one given below.
Villa No. 204, Lake View Estate, Lajpat Nagar, New Delhi, Delhi - 110024
A.Villa No. 204, Lake View Estate, Lajpat Nagar, New Delhi, Delhi - 110024
C.Villa No. 204, Lake View Estates, Lajpat Nagar, New Delhi, Delhi - 110024
D.Villa No. 240, Lake View Estate, Lajpat Nagar, New Delhi, Delhi - 110024
Solution
Address matching
(b) drops 'No.' and joins 'Lakeview'; (c) writes 'Estates' with an s.
(d) changes the villa number to 240.
Only (a) is identical to the given address.
Hence option (a).
4
Consider the following statement and choose the option that follows.
Problem: The issue of heavy traffic jams in the main parts of the city during the morning and evening peak hours.
Course of Action:
I. The government should improve the frequency and quality of public transport (like buses and metro).
II. The traffic police should ban the entry of private vehicles in the main areas during peak hours.
A.Only I follows
B.Only II follows
C.Both I and II follow
D.Neither I nor II follows
Solution
Course of action
Better public transport gives commuters a real alternative, so fewer private vehicles hit the road — I is a practical solution.
A blanket ban on private vehicles is drastic and would create fresh hardship for the public — II is not advisable.
A course of action must solve the problem without creating a bigger one.
Hence Only I — option (a).
Number puzzle (ab + a − b)
Rule: a @ b = (a × b) + (a − b).
Check: 7×3 + 4 = 25 ✓; 9×5 + 4 = 49 ✓; 10×2 + 8 = 28 ✓.
8 @ 6 = 48 + 2.
= 50 — option (a).
6
If 'Q' denotes 'addition', 'C' denotes 'subtraction', 'R' denotes 'multiplication', and 'U' denotes 'division', then what will be the value of the following expression?
(48 U 8 Q 25 C 6 R 4 Q 3) C (25 U 5 R 3 C 4 R 3)
The given statements are followed by two conclusions. Find out which conclusion is TRUE based on the given statements.Statements: A > B = C, D ≥ E < B, F = A = G, E > H > I
Conclusions:
I. B = F
II. B > F
A.Only conclusion I is true
B.Only conclusion II is true
C.Both conclusion I and II are true
D.Neither conclusion I nor II is true
Solution
Coded inequality
F = A and A > B, so B is definitely SMALLER than F.
Therefore B = F is false and B > F is also false.
The true relation would be B < F, which is not offered.
Hence Neither — option (d).
8
A is the son of B. B is the brother of C. C is the son of D. How is A related to D?
A.Father
B.Son
C.Grandson
D.Uncle
Solution
Blood relation
B and C are brothers, and C is D’s son — so B is also D’s son.
A is B’s son, i.e. one generation below B.
So A is D’s grandson.
Hence option (c).
9
Complete the series:
1331, 10648, 35937, ?, 166375
A.15478
B.85184
C.96637
D.67895
Solution
Cubes of multiples of 11
These are cubes of multiples of 11: 11³ = 1331, 22³ = 10648, 33³ = 35937.
The missing term is 44³.
44³ = 85184 (and 55³ = 166375 ✓).
Hence option (b).
10
Identify the assumptions that must hold for the statement to be valid, then choose the correct option.Statement: The Right to Information (RTI) Act is a landmark law that gives Indian citizens the right to obtain information from public authorities, thereby promoting transparency and accountability in the functioning of the government. However, this Act also includes some exemption provisions, which restrict access to certain information related to national security, strategic interests, and personal privacy.
Assumptions:
I. A primary objective of RTI is to bring transparency in government functioning.
II. Due to the exemption provisions, the RTI Act is completely ineffective in empowering citizens.
III. In a democratic governance, it is necessary to strike a balance between citizens' access to information and the nation's security.
A.Only I and II are implicit
B.Only I and III are implicit
C.Only I is implicit
D.All I, II, and III are implicit
Solution
Statement — assumptions
The statement itself says RTI promotes transparency and accountability — I is implicit.
The exemptions for security and privacy make sense only if a balance is thought necessary — III is implicit.
II calls the Act COMPLETELY ineffective, which contradicts the statement’s praise of it.
Hence Only I and III — option (b).
11
Read the following statement carefully and identify the conclusion that follows.Statement: The central bank has increased the interest rates on loans.
Conclusions:
I. The interest rates on home loans and car loans will increase.
II. People will stop saving completely.
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
Home and car loans are ordinary bank loans, so their rates rise with the policy rate — I follows.
Higher rates usually ENCOURAGE saving; stopping saving completely is an extreme claim — II does not follow.
So only the first conclusion holds.
Hence option (a).
12
Read the following statement carefully and identify the conclusion that follows.Statement: The use of online food delivery apps has increased significantly in recent years.
Conclusions:
I. People are valuing convenience and time-saving more.
II. People no longer like to dine out at restaurants.
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
Ordering food at home saves time and effort, so rising use does suggest a preference for convenience — I follows.
II says people NO LONGER like dining out — an extreme claim; both habits can coexist.
So only the first conclusion holds.
Hence option (a).
13
Find the option that best completes the analogy.
PQ : XY :: JF : ?
A.RN
B.OP
C.QR
D.KL
Solution
Analogy (+8)
P(16) + 8 = X(24) and Q(17) + 8 = Y(25).
So each letter moves 8 places forward.
J(10) + 8 = R(18) and F(6) + 8 = N(14).
Hence RN — option (a).
14
If "PRAYAG" is written as "GAYARP", how is "FOOLPUR" written?
A.ROPLUUF
B.RUPLOOF
C.RNPLOUF
D.RUNUOOF
Solution
Word reversal
PRAYAG written backwards gives GAYARP — the letters are simply reversed.
Reverse FOOLPUR letter by letter: R, U, P, L, O, O, F.
That is RUPLOOF.
Hence option (b).
15
Find the odd one out from the given alternatives:
A.Pollution
B.Afforestation
C.Deforestation
D.Climate Change
Solution
Environment — odd one
Pollution, deforestation and climate change are all environmental PROBLEMS.
Afforestation — planting new forests — is a SOLUTION to such problems.
So it belongs to a different category.
Hence option (b).
16
What comes next?
RST, STU, TUV, UVW, VWX, WXY, ?, YZA, ZAB
A.XYZ
B.YZA
C.UXY
D.WSY
Solution
Consecutive triplets
Each cluster has three consecutive letters and shifts one step forward.
After WXY the next starting letter is X.
So the cluster is X, Y, Z.
Hence XYZ — option (a).
17
A train 90 m long passes a point in 6 s. Find the speed of the train.
A.36 km/h
B.54 km/h
C.50 km/h
D.60 km/h
Solution
Speed of a train
To pass a point the train covers its own length.
Speed = = 15 m/s.
Convert: 15 × = 54.
= 54 km/h — option (b).
Introducing a woman, Viru said, "She is the daughter of the only child of my grandfather." How is the woman related to Viru?
A.Aunt
B.Sister
C.Niece
D.Cousin
Solution
Blood relation
The only child of Viru's grandfather must be Viru's own father.
So the woman is the daughter of Viru’s father.
That makes her Viru’s sister.
Hence option (b).
23
If '+' means '×', '×' means '−', '−' means '÷', then 15 − 5 + 2 × 3 = ?
The series given below contains a sequence of numbers. Accordingly identify the incorrect number.
25, 29, 37, 53, 89
A.29
B.37
C.25
D.89
Solution
Wrong term in series
Differences: 29 − 25 = 4, 37 − 29 = 8, 53 − 37 = 16.
The gaps double each time, so the next gap should be 32.
53 + 32 = 85, but the series shows 89.
So 89 is incorrect — option (d).

The same 25 questions, but with a timer and the answers hidden — 15 minutes.
Each cluster has three consecutive letters and every cluster moves back by 3.
P, M, J, G → next first letter is D.
So the cluster is D, E, F.
Hence DEF — option (c).
Rule: a @ b = (a × b) + (a − b).
Check: 7×3 + 4 = 25 ✓; 9×5 + 4 = 49 ✓; 10×2 + 8 = 28 ✓.
8 @ 6 = 48 + 2.
= 50 — option (a).
Replace the letters: (48 ÷ 8 + 25 − 6 × 4 + 3) − (25 ÷ 5 × 3 − 4 × 3).
First bracket: 6 + 25 − 24 + 3 = 10.
Second bracket: 15 − 12 = 3.
10 − 3 = 7 — option (d).
F = A and A > B, so B is definitely SMALLER than F.
Therefore B = F is false and B > F is also false.
The true relation would be B < F, which is not offered.
Hence Neither — option (d).
B and C are brothers, and C is D’s son — so B is also D’s son.
A is B’s son, i.e. one generation below B.
So A is D’s grandson.
Hence option (c).
These are cubes of multiples of 11: 11³ = 1331, 22³ = 10648, 33³ = 35937.
The missing term is 44³.
44³ = 85184 (and 55³ = 166375 ✓).
Hence option (b).
P(16) + 8 = X(24) and Q(17) + 8 = Y(25).
So each letter moves 8 places forward.
J(10) + 8 = R(18) and F(6) + 8 = N(14).
Hence RN — option (a).
PRAYAG written backwards gives GAYARP — the letters are simply reversed.
Reverse FOOLPUR letter by letter: R, U, P, L, O, O, F.
That is RUPLOOF.
Hence option (b).
Each cluster has three consecutive letters and shifts one step forward.
After WXY the next starting letter is X.
So the cluster is X, Y, Z.
Hence XYZ — option (a).
To pass a point the train covers its own length.
Speed = = 15 m/s.
Convert: 15 × = 54.
= 54 km/h — option (b).
Rule: a & a = a² × 2.
Check: 3² × 2 = 18 ✓; 4² × 2 = 32 ✓.
5 & 5 = 25 × 2.
= 50 — option (a).
CHAIR → DGYKS: C+1 = D, H−1 = G, A−2 = Y, I+2 = K, R+1 = S.
So the shifts are +1, −1, −2, +2, +1.
WORLD: W+1 = X, O−1 = N, R−2 = P, L+2 = N, D+1 = E.
Hence XNPNE — option (d).
Machines and days are inversely proportional: M₁ × D₁ = M₂ × D₂.
4 × 12 = 3 × x.
x = .
= 16 days — option (a).
Rule: a # b = (a² + b²) − 3.
Check: (36 + 4) − 3 = 37 ✓; (16 + 9) − 3 = 22 ✓.
6 # 5 = (36 + 25) − 3.
= 58 — option (c).
The only child of Viru's grandfather must be Viru's own father.
So the woman is the daughter of Viru’s father.
That makes her Viru’s sister.
Hence option (b).
Each term = previous × 2 + 1.
3×2+1 = 7, 7×2+1 = 15, 15×2+1 = 31 ✓.
Next: 31 × 2 + 1 = 63 (and 63 × 2 + 1 = 127 ✓).
Hence option (a).
Differences: 29 − 25 = 4, 37 − 29 = 8, 53 − 37 = 16.
The gaps double each time, so the next gap should be 32.
53 + 32 = 85, but the series shows 89.
So 89 is incorrect — option (d).
