Q&A: practice questions with answers

Concept: Pair = subject of study : what it studies.

1. Epistemology is the philosophical study of knowledge (how we know what we know).
2. Jurisprudence is the science/philosophy of law.
3. Reality → metaphysics, Logic → reasoning, Ethics → moral philosophy; none fits jurisprudence.

Trick: 'Juris' (Latin) = law/right — words like jurist, jurisdiction all point to law.

Answer: (C) Law

Concept: Locate both letters, then count letters strictly between them.

1. SIGNATURE → positions: S1 I2 G3 N4 A5 T6 U7 R8 E9.
2. First consonant = S (1), last vowel = E (9).
3. Letters between = 9 − 1 − 1 = 7 (I, G, N, A, T, U, R).

Trick: Between positions p and q = q − p − 1.

Answer: (C) 7

Concept: Track each position of the cluster separately.

1. 1st letters: M, N, O, P, Q (+1).
2. 2nd letters: N, O, P, Q, R (+1).
3. 3rd letters: K, J, I, H, G (−1).
4. Missing term = PQH.

Trick: The 1st letter must be P (between O and Q) — only PQH starts with P.

Answer: (C) PQH

Concept: Each position follows its own constant jump (alphabet is cyclic).

1. 1st: Q → S → U → W (+2).
2. 2nd: A → D → G → J (+3).
3. 3rd: Z(26) → F(6) → L(12) → R(18) (+6, wrapping after Z).
4. Missing cluster = UGL.

Trick: First letter must be U — only option D (UGL) begins with U.

Answer: (D) UGL

Concept: Arrange events in the natural order of how a dispute ends.

1. Chaos (disorder) turns into an open Conflict.
2. Conflict → Negotiation (talks) → Resolution (settlement) → Harmony (peace).
3. Justice, Stability, Law do not fit naturally between chaos and negotiation.

Trick: Ask: 'What do people negotiate about?' — a conflict.

Answer: (B) Conflict

Concept: Find the common category of three words.

1. Hibiscus (gudhal), Tulip and Daisy are flowers.
2. Mango is a fruit — the odd one.

Yaad rakhein: Mango is also India's national fruit — easy to spot as non-flower.

Answer: (C) Mango

Concept: Terms are $n^3-n$ for n = 1, 2, 3 …

1. $1^3-1=0$, $2^3-2=6$, $3^3-3=24$, $4^3-4=60$.
2. Next: $5^3-5=125-5=120$.
3. Check: $6^3-6=216-6=210$ ✓

Trick: $n^3-n$ = $(n-1)·n·(n+1)$: $4\times 5\times 6=120$ — product of three consecutive numbers.

Answer: (C) 120

Concept: Two operations alternate: +1, then ×3 + (odd number).

1. $3+1=4$; $4\times 3+1=13$.
2. 13 + 1 = 14; $14\times 3+3=45$.
3. $45+1=46$; $46\times 3+5=143$ ✓

Trick: Pairs 3,4 and 45,46 differ by 1 → so 13 and ? also differ by 1 → 14.

Answer: (A) 14

Concept: A conclusion must follow directly from the statement, not from guesses.

1. 'No student failed' = every student passed → II follows.
2. The statement gives no reason for the result; 'exam was easy' is an assumption → I does not follow.

Trick: Reject conclusions that add a cause/reason not given in the statement.

Answer: (B) Only Conclusion II follows

Concept: An assumption is what the writer takes for granted; it cannot contradict the statement.

1. 'Promises to improve diagnosis accuracy' → AI can enhance accuracy: I implicit.
2. 'Privacy concerns hinder adoption' → privacy is a real challenge: II implicit.
3. III says there are no concerns — opposite of the statement, so not implicit.

Trick: Any assumption that contradicts the statement is eliminated instantly — removes options with III.

Answer: (A) Only I and II are implicit

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

1. GUILDER sorted: D E G I L R U.
2. 5th from left = L; 4th from right = I.
3. Between I and L in the alphabet: J, K → 2 letters.

Trick: Alphabet gap = |12 − 9| − 1 = 2 (L = 12, I = 9).

Answer: (A) Two

Concept: Take only the specified letters and form valid words using each once.

1. ELEVATE: 1st E, 2nd L, 5th A, 6th T → letters E, L, A, T.
2. Valid words: LATE, TALE, TEAL.
3. Total = 3.

Trick: Fix the starting letter and test: L-ATE, T-ALE, T-EAL — quick systematic scan.

Answer: (C) 3

Concept: Compare every part — house no., name, city, PIN — character by character.

1. 1: house no. 117B ≠ 17B.
2. 3: 'Tower' and PIN 300018 differ.
3. 4: PIN 302017 ≠ 302018.
4. Only 2 is exactly identical.

Trick: Check the numbers (house no. and PIN) first — most traps hide there.

Answer: (A) 2 Only

Concept: Find the shift from first pair, apply to the second.

1. E(5) → M(13): +8; K(11) → S(19): +8.
2. G(7) + 8 = O(15); Q(17) + 8 = Y(25).
3. Answer = OY.

Trick: All options start with O, so only check Q + 8 = Y.

Answer: (C) OY

Concept: Split into pairs and reverse each pair.

1. NU|MB|ER → UN|BM|RE.
2. GH|SO|TS → HG|OS|ST.
3. Result = HGOSST.

Trick: Last two letters must be ST (TS reversed) — only HGOSST ends in ST.

Answer: (C) HGOSST

Concept: Decode from the end of the sentence backwards.

1. Girl's mother's only son = girl's brother.
2. Boy = son of her brother → boy is her nephew.
3. Hence, relative to the boy, the girl is his bua — an aunt.

Trick: Speaker is female and one generation above → only 'Aunt' fits among options.

Answer: (C) Aunt

Concept: Terms should be 2!, 3!, 4!, 5!, 6!, 7!.

1. 2! = 2, 3! = 6, 4! = 24.
2. 5! = 120, but 122 is given.
3. 6! = 720, 7! = 5040 ✓ — so 122 is wrong.

Trick: Every factorial from 5! onwards ends in 0 — 122 can't be one.

Answer: (D) 122

Concept: Find the rule shared by three sets.

1. 9→18→36, 10→20→40, 16→32→64: each term ×2.
2. 17→34 (×2) but 34→102 is ×3.
3. So (17, 34, 102) is different.

Trick: Third term should be 4 × first: $4\times 17=68\ne 102$.

Answer: (C) (17, 34, 102)

Concept: Find the uniform shift between word and code.

1. X→Z, S→U, J→L, U→W, F→H: each +2.
2. READ: R→T, E→G, A→C, D→F.
3. Code = TGCF.

Trick: Check just the first letter: R + 2 = T leaves TGCF and THDF; E + 2 = G → TGCF.

Answer: (C) TGCF

Concept: Find a rule that fits both given examples.

1. Try $a\times b+b+1$: $6\times 3+3+1=22$ ✓.
2. $8\times 2+2+1=19$ ✓.
3. 9#1 = $9\times 1+1+1=11$.

Trick: Rule can be written as $(a+1)\times b+1$: $(6+1)\times 3+1=22$ — faster to apply.

Answer: (D) 11
