SSC CGL — Tier 1 — 2025 — 14 Sep 2025 — Shift I — Previous Year Paper — Kerala PSC PYQ Practice with Answers

Correct answer (Option D):\nLet us examine the pattern in each letter-number group. Each segment consists of a letter followed by its corresponding numerical position in the English alphabet (A=1, B=2, ..., Z=26).\nOption A: A=1 (noted as A3?), D=4 (D6?), G=7 (G9?). Wait, let's look at the gaps: A to D is +3, D to G is +3. The numbers are Letter Position + 2: 1+2=3, 4+2=6, 7+2=9.\nOption B: B=2 (+2=4), E=5 (+2=7), H=8 (+2=10). Gaps are +3 letters.\nOption C: C=3 (+2=5), F=6 (+2=8), I=9 (+2=11). Gaps are +3 letters.\nOption D: D=4 (+2=6), G=7 (+2=9), K=11 (+2=13). Note that G to K is a gap of +4 letters instead of +3.\nTherefore, Option D breaks the standard pattern.\n\nWhy others are wrong:\nOptions A, B, and C all follow a consistent internal shift rule of +3 letters and a standard offset rule where the number equals the letter's alphabetic rank plus 2.\n\nStudy tip:\nAlways cross-examine both the sequential letter intervals and the mathematical mapping between a letter and its accompanying digit in alphanumeric series.

Correct answer (Option D):\nLet us map the alphabet positions (A=1, B=2, C=3, etc.) for each group:\nOption A: B(2), E(5), H(8) -> The difference between consecutive letters is +3, and the digits exactly equal the letter position.\nOption B: C(3), F(6), I(9) -> The difference is +3, and digits equal the position.\nOption C: D(4), G(7), J(10) -> The difference is +3, and digits equal the position.\nOption D: E(5), H(8), K(11) -> The text says H9 and K13, which violates both the digit identity rule and the +3 letter spacing rule since H to K would be +3 but the text gives 9 and 13.\nHence, Option D is the odd group.\n\nWhy others are wrong:\nOptions A, B, and C rigorously adhere to the dual rule of constant +3 letter shifts combined with accurate alphabetical indexing values.\n\nStudy tip:\nWhen encountering colon-separated letter-number combinations, analyze letter-to-letter transformations independently from letter-to-number relationships first.

Correct answer (Option A):\nLet us decode the pattern by examining the mapping from FLOWER to GMPXFS:\nF → G (+1)\nL → M (+1)\nO → P (+1)\nW → X (+1)\nE → F (+1)\nR → S (+1)\nThe coding scheme is a straightforward consecutive forward shift of +1 for every letter.\nApplying this same +1 pattern to GARDEN:\nG → H\nA → B\nR → S\nD → E\nE → F\nN → O\nThis combined result forms 'HBSEFO', which accurately matches Option A.\n\nWhy others are wrong:\nOption B fails because the final two characters are incorrect. Option C reverses the positions of E and F. Option D finishes with an N instead of an O.\n\nStudy tip:\nLetter shifting systems are cornerstone elements of reasoning sections. Write down the full target transformation step-by-step to prevent trailing placement errors.

Correct answer (Option B):\nLet us decode the relation from the perspective of the speaker (the man):\nStep 1: Identify "my father's only son". For a male speaker, his father's only son must be the speaker himself.\nStep 2: Replace that phrase in the sentence. The statement simplifies directly to: "She is the daughter of myself."\nTherefore, the woman is the daughter of the man. Option B is correct.\n\nWhy others are wrong:\nOption A is incorrect because she is a daughter, not a sibling. Option C is incorrect as it implies a marital bond. Option D is incorrect because a niece represents a sibling's daughter, whereas this is his direct child.\n\nStudy tip:\nIn blood relation puzzles, always identify pointer pronouns such as "only son" or "only daughter" relative to the gender of the speaker first to simplify the lineage tree.

Correct answer (Option C):\nLet us break down the descriptive quote spoken by Ravi:\nStep 1: Identify the phrase "my father's only son". Since Ravi is a man, his father's only son refers directly to Ravi himself.\nStep 2: Substitute this back into the description: "She is the wife of Ravi."\nThus, the woman is Ravi's wife. This matches Option C perfectly.\n\nWhy others are wrong:\nOption A is wrong as a sister-in-law implies a brother's wife or a spouse's sister. Option B is a generation above. Option D represents an extended maternal or paternal relation.\n\nStudy tip:\nBreak down multi-generational statements from the inside out. Substituting descriptive statements with personal pronouns clears up linguistic confusion quickly.
