Sentence: "Reflections are clearer in calm waters." If each letter is mirrored using alphabetical symmetry (A↔Z, B↔Y…), what is the 4th letter of the 3rd word after mirroring?
A.c
B.W
C.x
D.z
Solution
Mirror letters (A↔Z)
Words: Reflections(1), are(2), clearer(3), in(4), calm(5), waters(6).
The 3rd word is "clearer"; its 4th letter is a.
Mirroring: a ↔ z.
Hence z — option (d).
2
Choose the address that is exactly the same as the one given below.
Flat 203, Sapphire building, Garia Station Rd., Kolkata, West Bengal - 600084
A.Flat 203, Saphire building, Garia Station Rd., Kolkata, West Bengal - 600084
B.Flat 203, Sapphire building, Garia Station Rd., Kolkata, West Bengal - 600084
C.Flat 203, Sapphire building, Gariya Station Rd., Kolkata, West Bengal - 600084
D.Flat 203, Sapphire building, Garia Station Road, Kolkata, West Bengal - 600084
Solution
Address matching
(a) misspells 'Saphire'; (c) writes 'Gariya' instead of 'Garia'.
(d) writes 'Road' in full instead of 'Rd.'.
Only (b) matches every character of the given address.
Hence option (b).
3
Which of the following alternative will fill the blanks?
s_u_sg_b_gu_
A.g, b, u, s, b
B.g, b, u, b, s
C.b, u, u, b, s
D.b, b, u, s, g
Solution
Repeating block (sgub)
The 12 letters split into three blocks of four.
Filling with g, b, u, s, b gives: sgub / sgub / sgub.
Each block is the same group "sgub" ✓.
Hence option (a).
4
Select the letter-cluster from among the given options that can replace the question mark (?) in the following series:
TBDF, THMR, TNVD, TTEP, ?
A.TZMB
B.TZNC
C.TZNB
D.TYNB
Solution
Letter series (+6, +9, +12)
The first letter T stays fixed.
2nd letters: B, H, N, T → +6 each ⇒ next is Z.
3rd letters: D, M, V, E → +9 each (cyclic) ⇒ next is N; 4th letters: F, R, D, P → +12 each ⇒ next is B.
Hence TZNB — option (c).
5
If 'A' denotes 'addition', 'C' denotes 'multiplication', 'B' denotes 'division', and 'D' denotes 'subtraction', then what will be the value of the following expression?
3.2 A (0.56 B 1.4 C 4) D 4 C 5 B 20 A 5
Letter–place value
Pattern: letter @ its place value @ the same letter.
C = 3 ✓, E = 5 ✓, G = 7 ✓.
But F is the 6th letter, not the 5th ✗.
Hence option (c).
7
What will come at the place of question mark?
3, 7, 15, 31, 63, ?
Identify the assumptions that must hold for the statement to be valid, then choose the correct option.Statement: The use of electric vehicles (EVs) in cities can significantly reduce air pollution and dependence on fossil fuels.
Assumptions:
I. Electric vehicles produce less pollution compared to petrol or diesel vehicles.
II. A major part of urban air pollution is caused by conventional fuel-based vehicles.
III. The production of electricity for EVs does not involve any pollution.
A.Only I and II are implicit
B.Only II and III are implicit
C.Only I is Implicit
D.All I, II and III are implicit
Solution
Statement — assumptions
EVs can cut pollution only if they pollute LESS than petrol/diesel vehicles — I is implicit.
The cut will be significant only if vehicles are a major source of urban pollution — II is implicit.
III is not assumed: electricity generation may itself pollute; the statement never denies that.
Hence Only I and II — option (a).
9
Read the following statement carefully and identify the conclusion that follows.Statement: The city recorded its highest rainfall in the last 30 years.
Conclusions:
I. The city’s drainage system might have failed.
II. Such heavy rainfall happens regularly.
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
Record rainfall makes drainage failure a reasonable possibility — the word 'might' keeps I safe, so I follows.
Being the highest in 30 years means such rain is RARE, not regular — II is contradicted.
So only the first conclusion holds.
Hence option (a).
10
How many meaningful four-letter English words can be formed using the first, third, fifth and sixth letters of the word "PLANET" (when counted from left to right), using each letter only once in each word?
A.One
B.Two
C.Three
D.Four
Solution
Word formation — PEAT
PLANET: P(1) L(2) A(3) N(4) E(5) T(6).
Required letters: P, A, E, T.
The only meaningful word from all four is PEAT (a kind of soil fuel).
One word — option (a).
11
In the following question, a pair of letters is given, followed by its corresponding product of alphabetical positions (A=1, B=2, …, Z=26). A second pair of letters is given without its product. Identify the correct product for the second pair that maintains the same relationship as the first.
M × O : 13 × 15 :: G × I : ?
A.7 × 9
B.5 × 9
C.6 × 10
D.7 × 8
Solution
Place-value products
Each letter is replaced by its alphabetical place value.
M = 13 and O = 15 ✓.
G is the 7th letter and I the 9th.
So G × I = 7 × 9 — option (a).
12
Complete the series.
A1, Z2, Y3, X4, ?
A.W5
B.V4
C.U5
D.X5
Solution
Series — letters back, numbers up
After the opening A, the letters run backwards: Z, Y, X, …
The next letter is W.
The numbers simply count 1, 2, 3, 4 → 5.
Hence W5 — option (a).
13
Find the odd one out from the given alternatives:
A.Article 15
B.Article 16
C.Article 18
D.Article 352
Solution
Fundamental Rights articles
Articles 15, 16 and 18 all fall under Fundamental Rights (Right to Equality).
Article 352 deals with the National Emergency — an emergency provision.
It belongs to a different part of the Constitution.
Hence option (d).
14
P is the daughter of Q. Q is the son of R. S is the wife of R. How is S related to P?
A.Aunt
B.Mother
C.Grandmother
D.Sister
Solution
Blood relation
Q is the son of R and S, so R and S are Q’s parents.
P is Q’s daughter, so P belongs to the next generation.
S is therefore P’s grandmother.
Hence option (c).
In a certain code language, each letter is assigned a unique digit. Based on the given codes for specific words, determine the code for the target word using the same logic.
If TQFFE is coded as 83551 and DPPM is coded as 9226, then how will TDPPQ be coded?
A.89231
B.89726
C.89223
D.83927
Solution
Letter–digit code
From TQFFE = 83551: T = 8, Q = 3, F = 5, E = 1.
From DPPM = 9226: D = 9, P = 2, M = 6.
TDPPQ = 8, 9, 2, 2, 3.
= 89223 — option (c).
If 'READ' is coded as T2#3, and 'DEAR' is coded as 32#T, then what is the code for 'DARE'?
A.3#T2
B.T#23
C.#32T
D.#32Y
Solution
Letter–symbol code
From READ = T2#3: R = T, E = 2, A = #, D = 3.
Check with DEAR = 3 2 # T ✓ — the same mapping holds.
DARE = D, A, R, E = 3, #, T, 2.
= 3#T2 — option (a).
19
What is the average of 5 consecutive odd numbers starting from 11?
A.17
B.15
C.20
D.25
Solution
Average of consecutive odds
The numbers are 11, 13, 15, 17, 19.
For evenly spaced numbers the average is the middle term.
Sum = 75, so average = .
= 15 — option (b).
20
If the given symbols mean:
'+' means 'divided by', '−' means 'multiplied by', '×' means 'minus', '÷' means 'plus'
Then, find the value of the following expression: 30×5÷32+16−2 = ?
Pointing to a photograph, Ram says, "Siya is the daughter of the only son of my father's wife." Who is Siya to Ram?
A.Sister
B.Cousin
C.Niece
D.Daughter
Solution
Blood relation
Ram's father's wife is Ram's mother.
Her ONLY son must be Ram himself.
So Siya is Ram’s own daughter.
Hence option (d).
22
If '×' = '+', '+' = '−', '−' = '÷', '÷' = '×', which equation is correct?
A.10+2×2−4=10
B.32÷2−4+5=11
C.12×2+4−1=27
D.8+4−2×1=10
Solution
Symbol substitution
Test option (b): 32÷2−4+5 becomes 32 × 2 ÷ 4 − 5.
BODMAS: 32 × 2 = 64, then 64 ÷ 4 = 16.
16 − 5 = 11 = RHS ✓ (the other options do not balance).
Hence option (b).
23
Read the following statements and evaluate the conclusions based on traditional syllogistic logic. Consider the statements to be absolutely true, even if they appear contrary to known facts.Statements:
All apples are fruits.
Some fruits are sweet.
Conclusions:
I. Some apples are sweet.
II. All sweet being fruits is a possibility.
A.Only Conclusion II follows
B.Both I and II follow
C.Only Conclusion I follows
D.Neither I nor II follows
Solution
Syllogism
The sweet fruits need not be the apple ones — they may be entirely different fruits, so I is NOT certain.
Nothing forbids every sweet thing from lying inside the circle of fruits, so that arrangement is possible — II follows as a possibility.
Possibility conclusions hold whenever no statement rules them out.
Hence Only II — option (a).
24
If '+' means '×', '−' means '÷', '×' means '+', then 8 − 2 × 3 + 6 = ?
Words: Reflections(1), are(2), clearer(3), in(4), calm(5), waters(6).
The 3rd word is "clearer"; its 4th letter is a.
Mirroring: a ↔ z.
Hence z — option (d).
The 12 letters split into three blocks of four.
Filling with g, b, u, s, b gives: sgub / sgub / sgub.
Each block is the same group "sgub" ✓.
Hence option (a).
The first letter T stays fixed.
2nd letters: B, H, N, T → +6 each ⇒ next is Z.
3rd letters: D, M, V, E → +9 each (cyclic) ⇒ next is N; 4th letters: F, R, D, P → +12 each ⇒ next is B.
Hence TZNB — option (c).
Pattern: letter @ its place value @ the same letter.
C = 3 ✓, E = 5 ✓, G = 7 ✓.
But F is the 6th letter, not the 5th ✗.
Hence option (c).
Each term = previous × 2 + 1.
3×2+1 = 7, 7×2+1 = 15, 15×2+1 = 31, 31×2+1 = 63 ✓.
Next: 63×2+1 = 126+1.
= 127 — option (b).
Each letter is replaced by its alphabetical place value.
M = 13 and O = 15 ✓.
G is the 7th letter and I the 9th.
So G × I = 7 × 9 — option (a).
After the opening A, the letters run backwards: Z, Y, X, …
The next letter is W.
The numbers simply count 1, 2, 3, 4 → 5.
Hence W5 — option (a).
Q is the son of R and S, so R and S are Q’s parents.
P is Q’s daughter, so P belongs to the next generation.
S is therefore P’s grandmother.
Hence option (c).
Rule: (first × second) + (first + second).
Check: (4×5) + (4+5) = 20 + 9 = 29 ✓; (3×6) + (3+6) = 18 + 9 = 27 ✓.
Apply: (1×6) + (1+6) = 6 + 7.
= 13 — option (b).
From TQFFE = 83551: T = 8, Q = 3, F = 5, E = 1.
From DPPM = 9226: D = 9, P = 2, M = 6.
TDPPQ = 8, 9, 2, 2, 3.
= 89223 — option (c).
Rule: a ∗ b = a² + b².
Check: 5² + 3² = 25 + 9 = 34 ✓; 6² + 4² = 36 + 16 = 52 ✓.
7 ∗ 2 = 49 + 4.
= 53 — option (c).
From READ = T2#3: R = T, E = 2, A = #, D = 3.
Check with DEAR = 3 2 # T ✓ — the same mapping holds.
DARE = D, A, R, E = 3, #, T, 2.
= 3#T2 — option (a).
Ram's father's wife is Ram's mother.
Her ONLY son must be Ram himself.
So Siya is Ram’s own daughter.
Hence option (d).
The sweet fruits need not be the apple ones — they may be entirely different fruits, so I is NOT certain.
Nothing forbids every sweet thing from lying inside the circle of fruits, so that arrangement is possible — II follows as a possibility.
Possibility conclusions hold whenever no statement rules them out.
Hence Only II — option (a).
