SSC CHSL 2025 PYQs

Concept: Facing north, right = our right; fix ends first.

1. U at seat 6 (right end).
2. R is between Q and S; T immediately left of S → block T S R Q.
3. P not at an end → P at seat 5, block fills seats 1–4: T S R Q P U.
4. Left end = T.

Trick: T must be just left of S, and nothing else can stand left of T in the block – T leads.

Answer: (A) T

Concept: Number seats along the boys' own right-hand direction (they face south).

1. S immediate right of W → W = 1, S = 2, P = 8.
2. Q between S and R → Q = 3, R = 4.
3. V third right of Q → V = 6; T not next to R → T = 7, U = 5.
4. Between S (2) and V (6): Q, R, U = 3.

Trick: Between = 6 − 2 − 1 = 3 once both seats are fixed.

Answer: (C) 3

Concept: 'If fail → not allowed' is equivalent to 'if allowed (participated) → did not fail'.

1. Rohit participated in the National Games.
2. So he certainly did not fail the fitness test.
3. Topping, months of practice or an exemption are not stated – cannot be inferred.

Trick: Infer only what must be true – reject options that add new information.

Answer: (B) Rohit did not fail the physical fitness test.

Concept: Swap the two numbers everywhere, then solve by BODMAS.

1. 3 ↔ 8: $8\times 5+3-6÷1$.
2. $6÷1=6$; $8\times 5=40$.
3. $40+3-6=$ 37.

Trick: Only the 3 and 8 move – every other number stays as it is.

Answer: (C) 37

Concept: Swap 4 and 5 in each equation, then check the value.

1. I: $6\times 5+4-10÷2=30+4-5=29$ ✔ (correct).
2. II: $8+5\times 3-4÷1=8+15-4=19\ne 25$ ✘.
3. So only II is NOT correct.

Trick: The question asks for the wrong one – don't pick the equation that works.

Answer: (B) Only II

Concept: Find the position-wise shift from word to code.

1. GLOW → CIKS: G−4 = C, L−3 = I, O−4 = K, W−4 = S.
2. FISH → BFOD confirms −4, −3, −4, −4.
3. DARK: D−4 = Z, A−3 = X, R−4 = N, K−4 = G → ZXNG.

Trick: First letter D − 4 = Z already leaves only ZXNG and ZXMF; R − 4 = N decides.

Answer: (A) ZXNG

Concept: Letters shift alternately by −5 and −6 (wrap around Z/A).

1. HEAD → CYVX: H−5 = C, E−6 = Y, A−5 = V, D−6 = X.
2. MILK → HCGE confirms the same pattern.
3. PENT: P−5 = K, E−6 = Y, N−5 = I, T−6 = N → KYIN.

Trick: Use the last letter: T − 6 = N separates KYIN from KYIM.

Answer: (C) KYIN

Concept: Treat the two letters and the number as three separate series.

1. 1st letters J, G, D, A → back 3 → X.
2. 2nd letters S, P, M, J → back 3 → G.
3. Numbers 400, 440, 480, 520 → +40 → 560.

Trick: Number 560 cuts options to XG560, YG560, WH560; A − 3 = X finishes it.

Answer: (A) XG560

Concept: Split each term into letter parts and a number part.

1. 1st letters A, G, M, S → +6 → Y.
2. 2nd letters D, J, P, V → +6 → B (after Z).
3. Numbers 10, 20, 40, 80 → ×2 → 160.

Trick: In each term the 2nd letter is 3 ahead of the 1st (A→D, G→J): Y + 3 = B.

Answer: (A) YB160

Concept: Letters move +2; $\text{number}=\text{previous}\times 3+2$.

1. Letters: B, D, F, H, J and E, G, I, K, M.
2. Numbers: $15\times 3+2=47$, $47\times 3+2=143$.
3. $143\times 3+2=$ 431; check $431\times 3+2=1295$ ✔.

Trick: HK is in options A and D; $1295÷3\approx 431$ rules out 430.

Answer: (D) HK431

Concept: Decode the relation from the innermost phrase outward.

1. Son's father-in-law = father of the son's wife.
2. His only daughter = the son's wife herself.
3. Son's wife = Ramesh's daughter-in-law.

Trick: 'Only daughter of X's father-in-law' always = X's wife.

Answer: (A) Daughter-in-law

Concept: Simplify the chain step by step.

1. Only daughter of Amit's wife's mother = Amit's wife.
2. Husband of Amit's wife = Amit.
3. Mother of Amit = Amit's mother.

Trick: The chain loops back to the speaker himself – so the woman is simply 'mother of Amit'.

Answer: (A) Mother

Concept: Apply two separate rules: vowels move 3 forward, consonants 1 back.

1. C→B, H→G, A→D, M→L
2. P→O, I→L, O→R, N→M
3. Code: BGDLOLRM

Trick: Check only the 5th letter: P−1 = O. That removes A (P) ; then 6th letter I+3 = L removes D (K). Answer in 10 seconds.

Answer: (B) BGDLOLRM

Concept: The best response fixes the root cause while keeping the team together.

1. The real complaint: members were not consulted.
2. Talking to them, explaining reasons and involving them later repairs trust.
3. Ignoring, blaming or replacing them worsens the conflict.

Trick: In leadership questions, pick the option with communication + participation; reject anything extreme.

Answer: (C) Talk to them, explain your reasons, and involve them in future decisions

Concept: Draw the minimal Venn diagram and test each conclusion.

1. City and Village circles are separate.
2. Some villages are towns → the town part inside Village can never be a city → some towns are not cities (I follows).
3. II 'No town is a village' contradicts 'Some villages are towns' → false.

Trick: 'No A is B' + 'Some B are C' ⇒ always 'Some C are not A'.

Answer: (A) Only conclusion I follows.

Concept: Only what is certain in every diagram is a valid conclusion.

1. All diabetics ⊂ Rich; Teachers only partly overlap Rich.
2. Diabetics may or may not touch Teachers → conclusion 1 is only possible, not certain.
3. All diabetics are rich ⇒ some rich are diabetic (conversion) → conclusion 2 follows.

Trick: 'All A are B' always gives 'Some B are A'.

Answer: (D) Only conclusion 2 can be drawn

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

1. Sushma from left = 30 − 12 + 1 = 19.
2. Reena from left = 5.
3. Between = 19 − 5 − 1 = 13.

Trick: Between = Total − (left rank + right rank) = 30 − (5 + 12) = 13 (when they don't overlap).

Answer: (B) 13

Concept: $\text{Share}=\frac{\text{its ratio part}}{\text{sum of parts}}\times \text{total}$.

1. Sum of parts = $3+4+5=12$.
2. $Y=\frac{4}{12}\times 1200=\frac{1}{3}\times 1200$.
3. Y = ₹400.

Trick: Y's part 4 out of 12 = exactly one-third of the total.

Answer: (A) ₹400

Concept: Emotional intelligence = self-awareness + responsible action.

1. The faulty plan was the manager's responsibility.
2. Accepting it and planning improvements rebuilds trust and prevents repeats.
3. Blaming others, ignoring, or endless apologies achieve nothing.

Trick: Best EI answers combine 'accept' + 'improve'.

Answer: (B) Accept your mistake and plan for improvement

Concept: The words are the levels of Bloom's taxonomy in order.

1. Order: Knowledge → Comprehension → Application → Analysis → Synthesis/Evaluation.
2. Memory, sensation and information are not levels in this hierarchy.

Trick: Bloom's order mnemonic: K C A A S E – 'Kids Can Always Ask Smart Explanations'.

Answer: (B) Analysis
