Instrument analogy Relationship: instrument : what it measures. A barometer measures atmospheric pressure. An odometer, fitted in vehicles, measures the DISTANCE travelled (a speedometer measures speed). Hence Distance — option (a).

Workplace analogy Relationship: professional : his place of work. A judge works in a court. A doctor works in a hospital — patient and treatment describe whom/what he handles, not the place. Hence Hospital — option (d).

Consecutive letter triplets Each cluster contains three consecutive letters. F-G-H, then I-J-K, then L-M-N — every cluster starts right after the previous one ends. After N come O, P, Q. Hence OPQ — option (a).

Consecutive letter triplets Again three consecutive letters per cluster. G-H-I, J-K-L, M-N-O — an unbroken run of the alphabet. The next three letters after O are P, Q, R. Hence PQR — option (b).

Letter series (+3 each) Track each position: O, R, U, X — every letter moves +3. The same +3 applies to all three positions (Z→C→F→I and E→H→K→N). Next: X+3 = A (cyclic), I+3 = L, N+3 = Q. Hence ALQ — option (c).

Letter series (+3, +6, +9) The 1st letter T is constant in every cluster. 2nd letters move +3 (G, J, M, P → S); 3rd letters move +6 (M, S, Y, E → K). 4th letters move +9 cyclically (S, B, K, T → C). Hence TSKC — option (d).

Letter series (+3, +5, +7) D is constant at position 1. 2nd letters move +3 (D, G, J, M → P); 3rd letters move +5 (K, P, U, Z → E, cyclic). 4th letters move +7 cyclically (O, V, C, J → Q). Hence DPEQ — option (b).

Series (×2 + n) Test doubling: 5×2 = 10, but the term is 11 — one more. Rule: each term = (previous × 2) + 1, + 2, + 3, + 4… in turn: 11×2+2 = 24 ✓; 24×2+3 = 51 ✓; 51×2+4 = 106 ✓. Next term = 106 × 2 + 5 = 212 + 5. = 217 — option (b).

Alphabetical arrangement — FRIENDLY FRIENDLY arranged alphabetically: D, E, F, I, L, N, R, Y. Second from the left = E; third from the right = N. Letters between E and N in the alphabet: F, G, H, I, J, K, L, M — count them: 8. Hence option (c).

Address matching Compare tiny details: dots and hyphens matter. Address 1 writes 'Sanjeev T' without the dot; address 4 writes 'Block B' without the hyphen. Addresses 2 and 3 match character-for-character. Hence 2 and 3 — option (b).

Address matching Address 1 drops the dot after 'Dr' and the comma after 'Residency'. Address 4 changes the PIN code to 302010. Addresses 2 and 3 are identical in every character, including PIN 302001. Hence 2 and 3 — option (b).

Opposite-letter analogy Check the first pair with opposite letters (A↔Z, B↔Y …): opposite of E = V, K = P, P = K, T = G — exactly VPKG ✓. So each letter is replaced by its opposite (position + opposite = 27). DINS: D→W, I→R, N→M, S→H. Hence WRMH — option (c).

Letter positions — product The rule: each letter is simply replaced by its alphabetical position. B = 2 and F = 6 — that gives 2 × 6 ✓. E is the 5th letter and L is the 12th. So E × L = 5 × 12 — option (c).

Row — students between First bring both to the same side: Pankaj's position from the LEFT = 50 − 17 + 1 = 34th. Ravi is 13th and Pankaj is 34th from the left. Students between them = 34 − 13 − 1 = 20. Hence option (c).

Pair swapping PROTOCOL → RPTOCOLO: every pair of letters is swapped — (PR)(OT)(OC)(OL) → (RP)(TO)(CO)(LO). Apply the same to PRINTING: split into pairs (PR)(IN)(TI)(NG). Swap each pair: (RP)(NI)(IT)(GN). Hence RPNIITGN — option (d).

Coding (−1 each) Compare letter by letter: L→K, I→H, G→F, H→G, T→S — every letter moves −1. Apply −1 to HOUSE: H→G, O→N, U→T, S→R, E→D. Hence GNTRD — option (d).

Blood relation Siya's father's wife is Siya's mother; her son is Siya's brother. Ram says that boy is 'my brother' — so Siya's brother is also Ram's brother. That means Ram and Siya share the same parents. Siya is Ram’s Sibling — option (b).

Squares of primes Recognise the terms: 4 = 2², 9 = 3², 25 = 5², 121 = 11². The bases 2, 3, 5, ?, 11 are consecutive PRIME numbers. The missing prime between 5 and 11 is 7, so the term is 7² = 49. Hence option (b).

Digit-sum divisor Check each: 24 → digit sum 6, and 24 ÷ 6 = 4 ✓ divides exactly. 28 → sum 10, 28 ÷ 10 ✗; 32 → sum 5, 32 ÷ 5 ✗. 43 → sum 7, 43 ÷ 7 ✗. Only 24 works — option (a).

Letter–number chains In options (a), (b) and (c) the letters move +3 each step (P→S→V, Q→T→W, R→U→X) and the numbers move +4 each step (2, 6, 10 / 3, 7, 11 / 4, 8, 12). In option (d): S→V is +3 but V→Z is +4; the numbers 5, 8, 13 move +3 and then +5. Both the letter chain and the number chain break only in (d). Hence option (d).

Letter–value–symbol groups Pattern in (a), (b) and (d): the letters move +3 each step AND the number is the alphabetical place value of its own letter (A1, D4, G7 / B2, E5, H8 / C3, F6, I9). In option (c): D4 is fine, but G is paired with 8 (G = 7) and G→L is a +5 jump. Both the place-value rule and the +3 rule fail in (c). Hence option (c).

Blood relation Work from inside: the father of Dev's brother is Dev's own father. The only daughter of Dev's father is Dev's sister. So the woman Ajay met is Dev’s sister. Hence option (d).

Blood relation 'My son's mother' is the man's own wife. 'The only daughter of your father' — if the listener is a woman, SHE herself is that only daughter. So the man’s wife is the listener — the man is her husband. Hence option (b).

Blood relation — chain The only son of Shreya's grandfather is Shreya's FATHER. The granddaughter of Shreya's father is Shreya's DAUGHTER (her child's daughter — here, her own daughter). The man is the husband of Shreya’s daughter. Hence he is her Son-in-law — option (b).

Symbol substitution Replace the signs as instructed: 5 × 3 + 3 ÷ 1. BODMAS: multiplication and division first: 5 × 3 = 15 and 3 ÷ 1 = 3. Then add: 15 + 3 = 18. Hence 18 — option (c).
