Q&A: practice questions with answers

Concept: Look at each element separately: inner symbols shift position step by step, and the corner symbol follows its own cycle.

1. The three inner symbols (ω, ○, Y) and the blank spot occupy four side positions; at every step all of them shift one place anticlockwise.
2. Four shifts complete a full round, so figure 5 must have the same inner layout as figure 1.
3. The corner mark cycles ● → ▲ → ■ → ★, so figure 5 again shows ●.
4. Only option (C) has figure-1 layout with ● in the corner.

Trick: When a pattern moves one of four positions per step, term 5 = term 1. Just match the first figure.

Answer: (C) Figure (C)

Concept: The hidden figure must appear with every line in the same direction, since rotation is not allowed.

1. Figure X is like a box with all four corners cut by slant lines and one horizontal line running across it.
2. Options (A), (C), (D) contain long diagonals but no matching pair of slanting corner cuts, so the top part of X cannot be traced in them.
3. Option (B) has slanted corners and a full horizontal line – X fits exactly.

Trick: Pick the most unusual part of X (here the slanted corner cuts) and scan options only for that part; others get eliminated fast.

Answer: (B) Figure (B)

Concept: Fix the sure blocks first (N–O pair), then place others using 'one person between' clues.

1. N is immediately left of O and N faces S → block N O.
2. One person between N and M → row 1 (from its own left): M, L, N, O.
3. Whoever faces P sits 2nd from the line's left end → L faces P (also O does not face P ✔).
4. Row 2 opposite M, L, N, O = R, P, S, Q; only S sits between P and Q ✔.

Trick: Check options against fixed facts: N faces S, so (D) 'N and R' is out; M can't face S either → only L–P remains plausible.

Answer: (B) L and P

Concept: Find the step pattern between consecutive letters of each cluster.

1. EDH: E→D = −1, D→H = +4.
2. QPT: −1, +4; ZYC: −1, +4 (Y +4 wraps to C).
3. TTW: T→T = 0, T→W = +3 – pattern broken.

Trick: A repeated letter (TT) means a gap of 0 – usually that cluster is the odd one.

Answer: (B) TTW

Concept: Each fold doubles the cut; unfold in reverse order and mirror the mark across each fold line.

1. Paper is folded twice (horizontal + vertical), so the cut passes through 4 layers → the design appears in all 4 quarters.
2. Opening the vertical fold gives a left–right mirror image; opening the horizontal fold gives an up–down mirror image.
3. So every quarter must show the slanted double arrow with both small circles, arrows tilting oppositely in neighbouring quarters.
4. (D) loses a circle per quarter; (B), (C) put circles in the middle – only (A) fits.

Trick: Count first: 2 folds → 4 copies of every hole/cut. Reject options with the wrong count, then check mirror direction.

Answer: (A) Figure (A)

Concept: Differences between terms increase by 1.

1. Differences: 10, 11, 12, 13.
2. Next difference = 14.
3. ? = 147 + 14 = 161.

Trick: When gaps rise by 1, next term = last term + (last gap + 1) = 147 + 14.

Answer: (B) 161

Concept: Find the shift for each position and apply the same shifts.

1. NEYG → PHBI: N+2, E+3, Y+3 (=B), G+2.
2. LAVS → NDYU: same +2, +3, +3, +2 ✔.
3. HCTB: H+2 = J, C+3 = F, T+3 = W, B+2 = D → JFWD.

Trick: First letter H+2 = J – only option (A) starts with J. Done in 5 seconds.

Answer: (A) JFWD

Concept: 20 places and 5 blanks → split into 5 groups of 4 and compare same-position letters.

1. Groups: _DGI, K_JL, NJ_O, QMP_, TPS_.
2. 2nd letters D, ?, J, M, P go up by 3 → blank = G. 3rd letters G, J, ?, P, S → blank = M.
3. 4th letters I, L, O, ?, ? → R, U. 1st letters ?, K, N, Q, T → H.
4. Blanks in order: H, G, M, R, U.

Trick: First blank: column K, N, Q, T steps +3, so it is H – this alone removes (C) and (D); 2nd blank G then picks (A).

Answer: (A) HGMRU

Concept: A word present in both sentences gets the code present in both codes.

1. Common word in 'are you busy' and 'you need rest' = you.
2. Common code in 'mg rc tp' and 'rc as bo' = rc.
3. So you = rc.

Trick: Just intersect: common word ↔ common code.

Answer: (A) rc

Concept: Write the letters in A–Z order and compare position by position.

1. SYMPHONY → alphabetical: H M N O P S Y Y.
2. Compare: S/H, Y/M, M/N, P/O, H/P, O/S, N/Y, Y/Y.
3. Only the 8th letter (Y) stays the same → One.

Trick: Two Y's are the largest letters, so they go to positions 7–8; the word already ends in Y → at least 1 match, check the rest quickly.

Answer: (D) One

Concept: Swap the signs first, then solve using BODMAS.

1. After swapping (+↔×, −↔÷): $18-90÷5+11\times 2$.
2. $90÷5=18$; $11\times 2=22$.
3. $18-18+22=22$.

Trick: Write the new expression fully before solving – most mistakes come from swapping only one pair.

Answer: (C) 22

Concept: The word repeated in both sentences takes the code repeated in both codes.

1. 'get the book' and 'book is good' share only 'book'.
2. 'as pg nk' and 'nk ml bt' share only 'nk'.
3. So book = nk.

Trick: Match common to common – no need to decode other words.

Answer: (D) nk

Concept: Two folds → 4 layers; unfolding mirrors the mark across each fold line.

1. Folds: top half down, then left half to the right → cut lies in the bottom-right quarter through 4 layers.
2. Opening the vertical fold mirrors it left–right; opening the horizontal fold mirrors both copies up–down.
3. So all 4 quarters carry the mark, each bracket opening towards the centre.
4. (A) has only 2 copies, (C) all face up, (D) not mirrored → (B).

Trick: Mirror images across a fold always face each other – look for marks that 'point to the centre'.

Answer: (B) Figure (B)

Concept: Differences are consecutive even numbers.

1. Differences: 8, 10, 12, 14.
2. Next difference = 16.
3. ? = 79 + 16 = 95.

Trick: Second difference is constant (2), so next gap = last gap + 2.

Answer: (A) 95

Concept: Subset goes inside its class; an unrelated class is drawn separately.

1. Mango is a fruit → Mango circle inside Fruit circle.
2. Cauliflower is a vegetable → no overlap with Fruit or Mango.
3. Required: small circle inside a big one + one separate circle.

Trick: Ask 'is every A a B?' for each pair – yes means inside, no common member means separate.

Answer: (B) Figure (B)

Concept: Fix the end positions first, then fill pairs.

1. No one left of F → F at seat 1; four between F and E → E at seat 6.
2. Three to the left of Z → Z at seat 4.
3. X immediately left of G → X = 2, G = 3; Y = 5.
4. Between F(1) and Y(5): X, G, Z = 3.

Trick: People between seats a and b = |a − b| − 1 = 5 − 1 − 1 = 3.

Answer: (A) Three

Concept: Decode each symbol pair and build the family tree.

1. Q × R: Q is R's wife. R − S: R is S's brother.
2. S ÷ T: S is T's father. T + U: T is U's mother.
3. So S is the father of U's mother → mother's father.

Trick: Only the last two links (S ÷ T + U) matter for S–U: father of the mother.

Answer: (C) Mother's father

Concept: Every letter moves 4 steps back from one term to the next.

1. DKC → ZGY: D−4 = Z, K−4 = G, C−4 = Y.
2. ZGY −4 → V C U.
3. Check: VCU −4 → RYQ ✔, RYQ −4 → NUM ✔.

Trick: Use the last letters only: C, Y, ?, Q, M → Y−4 = U; then middle G−4 = C picks VCU.

Answer: (D) VCU

Concept: Find the shift at each position and repeat it.

1. SBFU → VDHX: +3, +2, +2, +3.
2. HOXA → KQZD: +3, +2, +2, +3 ✔.
3. ZEPI: Z+3 = C, E+2 = G, P+2 = R, I+3 = L → CGRL.

Trick: Z+3 wraps to C – only option (A) starts with C.

Answer: (A) CGRL

Concept: A conclusion follows only if it is true in every possible diagram.

1. All balms are ears and all balms are legs → balms lie inside both legs and ears.
2. I: Fingers touch only legs; they may miss balms → 'Some fingers are balms' does not follow.
3. II: Balms are common to legs and ears → 'Some legs are ears' follows.

Trick: Two 'All' statements with the same subject (All A are B, All A are C) always give 'Some B are C'.

Answer: (A) Only conclusion (II) follows.
