SSC CGL 2025 PYQs

Concept: Decode the phrase from the end (my mother's father) inward.

1. Rekha's mother's father = maternal grandfather.
2. His only daughter = Rekha's mother.
3. The man's mother = Rekha's mother → he is her brother.

Trick: 'Only daughter of my mother's father' = my mother – replace the phrase directly.

Answer: (C) Brother

Concept: Apply both swaps, then evaluate each option.

1. A: $(25\times 2)+10=50+10=60$ ✓.
2. B: $(10\times 3)+25=55\ne 40$.
3. C: $(25\times 4)+10=110\ne 135$; D: $(10\times 1)+25=35\ne 40$.

Trick: Swap both pairs in one go while rewriting; then check from option A onwards.

Answer: (A) (10+2)×25=60

Concept: Decode symbols; a conclusion holds only if the signs point the same way.

1. P ∘ Q → P > Q; Q # R → Q ≤ R.
2. P > Q ≤ R: opposite signs, so P and R cannot be related.
3. Neither P > R nor P ≥ R follows.

Trick: Opposite-facing signs (> and ≤) on a common term = no definite relation.

Answer: (D) Neither I nor II is true

Concept: Substitute the signs and solve with BODMAS.

1. New expression: $25\times 10-18÷9$.
2. $18÷9=2$; $25\times 10=250$.
3. $250-2=248$.

Trick: Answer must be just below 250 (250 minus a small number) → 248.

Answer: (C) 248

Concept: Number = $10x+y$; reversing changes it by $9(y-x)$.

1. $10x+y=4(x+y)\to 6x=3y\to y=2x$.
2. $9(y-x)=27\to y-x=3$.
3. $x=3,y=6$ → number 36.

Trick: Test options: digit difference must be 3 ($27÷9$) and number = 4 × digit sum; $36=4\times 9$ ✓.

Answer: (C) 36

Concept: Pair = a device : the quantity it records.

1. Barometer records air pressure.
2. Odometer (in a vehicle's dashboard) records the total distance covered.
3. Speed is shown by the speedometer, so (B) is a trap.

Trick: Odo = road/way (Greek 'hodos') → distance on the road; Speedo → speed.

Answer: (A) Distance

Concept: Pair = professional : place where he works.

1. A judge hears cases in a court.
2. A doctor attends patients in a hospital.
3. Patient and treatment are linked to the doctor's work, not his workplace.

Trick: Make a sentence: 'A judge works in a ___' → use the same sentence for doctor.

Answer: (D) Hospital

Concept: Each term is a block of 3 consecutive letters, continuing the alphabet.

1. FGH → IJK → LMN: the alphabet simply runs on.
2. Letters after N: O, P, Q.
3. OPR breaks the run (R instead of Q).

Trick: Look only at the last letter: H, K, N → +3 each → Q. Only OPQ ends in Q.

Answer: (A) OPQ

Concept: Blocks of three consecutive letters follow each other.

1. GHI, JKL, MNO cover G to O without a gap.
2. Next three letters: P, Q, R.
3. PQS skips R, so it is out.

Trick: First letters G, J, M jump +3 → next starts with P; then just write P, Q, R.

Answer: (B) PQR

Concept: Each position moves forward by the same step (+3), wrapping after Z.

1. 1st letters: O→R→U→X→A (X+3 crosses Z to A).
2. 2nd letters: Z→C→F→I→L.
3. 3rd letters: E→H→K→N→Q.
4. Next term = ALQ.

Trick: Remember X+3 = A (X=24, 24+3=27 → 27−26=1).

Answer: (C) ALQ

Concept: Study each of the four positions separately; steps may differ.

1. 1st letter: T stays the same.
2. 2nd: G, J, M, P → +3 → S.
3. 3rd: M, S, Y, E → +6 → K (E=5, 5+6=11).
4. 4th: S, B, K, T → +9 → C (20+9=29−26=3).
5. Next = TSKC.

Trick: Steps are +3, +6, +9 (table of 3). Options left after T,S: TSKE and TSKC — check only the last letter.

Answer: (D) TSKC

Concept: Fix the step for each position, wrapping after Z.

1. 1st: D constant.
2. 2nd: D, G, J, M → +3 → P.
3. 3rd: K, P, U, Z → +5 → E.
4. 4th: O, V, C, J → +7 → Q (J=10, 10+7=17).
5. Next = DPEQ.

Trick: Steps +3, +5, +7 are consecutive odd numbers. All options start DP, so check only letters 3 and 4.

Answer: (B) DPEQ

Concept: Each term = previous $\times 2+n$, where $n=1,2,3,\dots$

1. $11=2\times 5+1$, then $24=2\times 11+2$.
2. $51=2\times 24+3$ and $106=2\times 51+4$.
3. Next = $2\times 106+5=217$.

Trick: Terms roughly double: $106\times 2\approx 212$, so the answer is just above 212 → only 217 fits.

Answer: (B) 217

Concept: Sort the letters A→Z, pick the positions, then count the gap in the alphabet.

1. FRIENDLY sorted: DEFILNRY.
2. 2nd from left = E (5); 3rd from right = N (14).
3. Letters between = 14 − 5 − 1 = 8 (F to M).

Trick: Letters between two letters = difference of positions − 1.

Answer: (C) 8

Concept: Compare names, punctuation, block and PIN character by character.

1. No. 1: 'Sanjeev T' has no full stop after T.
2. No. 4: 'Block B' has no hyphen.
3. Nos. 2 and 3 agree in every mark.

Trick: Scan one detail at a time across all four (dot → hyphen → PIN) and strike out the odd ones.

Answer: (B) 2 and 3

Concept: Check every comma, full stop and digit.

1. No. 1: 'Dr' without a dot and no comma after 'Residency'.
2. No. 4: PIN 302010 instead of 302001.
3. Nos. 2 and 3 are exactly the same.

Trick: Always read PIN codes digit by digit — swapped digits are the commonest catch.

Answer: (B) 2 and 3

Concept: Each letter is replaced by its mirror letter (sum of positions = 27).

1. E(5)→V(22), K→P, P→K, T→G: matches VPKG.
2. D(4)→W(23), I(9)→R(18).
3. N(14)→M(13), S(19)→H(8).
4. DINS → WRMH.

Trick: Opposite pairs mnemonic: 'DeW', 'IRa', 'NaMe', 'SHe' → D-W, I-R, N-M, S-H.

Answer: (C) WRMH

Concept: Each letter is written as its place number in the alphabet.

1. B = 2, F = 6 → 2 × 6 (given).
2. E = 5, L = 12.
3. So E × L = 5 × 12.

Trick: EJOTY = 5, 10, 15, 20, 25 → E = 5; L is two after J(10) = 12.

Answer: (C) 5 × 12

Concept: Convert both ranks to the same end, then subtract.

1. Pankaj from left = 50 − 17 + 1 = 34.
2. Ravi from left = 13.
3. Between them = 34 − 13 − 1 = 20.

Trick: Shortcut: Between = Total − (left rank + right rank) = 50 − (13+17) = 20 (when they don't overlap).

Answer: (C) 20

Concept: Break the word into pairs and reverse each pair.

1. PR|OT|OC|OL → RP|TO|CO|LO = RPTOCOLO ✓.
2. PRINTING → PR|IN|TI|NG.
3. Reverse each: RP|NI|IT|GN = RPNIITGN.

Trick: All options begin RPNI; just check the last pair: NG → GN.

Answer: (D) RPNIITGN
