Q&A: practice questions with answers

Concept: When a folded paper is cut and opened, every cut is reproduced as a mirror image across each fold line.

1. Fold 1 brings the top half down; fold 2 brings the left half onto the right, so only the bottom-right quarter receives the cut.
2. Opening fold 2 mirrors the design into the bottom-left quarter (about the vertical line).
3. Opening fold 1 mirrors both into the top quarters (about the horizontal line), so the sheet is symmetric about both centre lines with the curved notch in every corner design.
4. Only option (B) shows all four corner designs, including the curved cuts, as exact mirror images of one another.

Trick: Two folds = 4 copies. Check one corner, then confirm the design is mirrored (not just copied) on both centre lines.

Answer: (B) the second figure

Concept: Find the operation linking the three numbers in each given set and test it on the options.

1. (53, 36, 25): $53-17=36$ and $36-11=25$.
2. (71, 54, 43): $71-17=54$ and $54-11=43$.
3. Rule: second $=$ first $-17$, third $=$ second $-11$.
4. (99, 82, 71): $99-17=82$ ✓, $82-11=71$ ✓. Others fail, e.g. $41-17=24\ne 23$.

Trick: Check the first difference (17) quickly in every option; only one survives.

Answer: (B) (99, 82, 71)

Concept: When two positions of a dice share one common face in the same place, the other faces seen around it follow one cyclic order, which fixes the opposite pairs.

1. Common face 1 is on top in both views, so the face opposite 1 is the unseen character 3.
2. Around 1 we see B→2 in view 1 and A→C in view 2; the only cyclic order around 1 is B, 2, A, C.
3. In a cycle of four faces, alternate faces are opposite: B ↔ A and 2 ↔ C.

Trick: Common top face → write the four side faces in one ring; faces two steps apart are opposite.

Answer: (B) 2

Concept: Look for an alternating (repeating) pattern among the problem figures.

1. Figure 3 is exactly the same as figure 1, so the series alternates: 1, 2, 1, 2, …
2. Hence the 4th figure must be the same as figure 2.
3. Figure 2: large inverted triangle with the right half black and a small line at its lower right; small upright triangle with the lower band black and top white.
4. Option (B) matches all details; (A) and (D) have the small triangle's top shaded, (C) is upright.

Trick: If figures 1 and 3 are identical, answer = copy of figure 2.

Answer: (B) the second figure

Concept: Find the repeating block of letters that fits the series.

1. Try a block of six letters: a b a b b a.
2. Series: a b a b b a | a b a b b a | a b a b b a.
3. So the blanks are a, b, a.

Trick: Total letters = 18; try blocks of 6 (18 ÷ 6 = 3 repeats).

Answer: (B) a, b, a

Concept: Check the differences between consecutive terms.

1. $171-144=27$, $200-171=29$ – differences increase by 2.
2. Next difference $=31$: $200+31=231$.
3. Check: $231+33=264$ ✓.

Trick: Differences 27, 29, 31, 33 are consecutive odd numbers.

Answer: (D) 231

Concept: Track each letter position separately using alphabet positions.

1. 1st letters: F, C, ?, W, T → $-3$ each: F→C→Z→W→T.
2. 2nd letters: O, K, ?, C, Y → $-4$: O→K→G→C→Y.
3. 3rd letters: H, E, ?, Y, V → $-3$: H→E→B→Y→V.
4. 4th letters: V, R, ?, J, F → $-4$: V→R→N→J→F.

Trick: Pattern −3, −4, −3, −4 for the four positions; wrap around after A (B − 3 = Y).

Answer: (B) ZGBN

Concept: If one face is common and in the same place in two views, the four faces around it follow a single cyclic order; alternate faces in that ring are opposite.

1. A is on top in both views, so the face opposite A is the unseen B.
2. Around A: view 1 shows 1→2, view 2 shows 3→C; the ring is 1, 2, 3, C.
3. Alternate faces are opposite: 1 ↔ 3 and 2 ↔ C.

Trick: Common face fixed → ring of four → faces two apart are opposite.

Answer: (B) 1

Concept: Compare the word and its code letter by letter.

1. BLOCK → LBCON: pairs swapped (BL→LB, OC→CO) and last letter $+3$ (K→N).
2. CABIN → ACIBQ: CA→AC, BI→IB, N$+3$→Q ✓.
3. SUITE: SU→US, IT→TI, E$+3$→H ⇒ USTIH.

Trick: Swap letters in pairs (1-2, 3-4) and shift the 5th letter forward by 3.

Answer: (A) USTIH

Concept: The given figure must appear inside an option in the same size and orientation (no rotation).

1. Key features: a long vertical line on the right, a stepped outline on its left joined to it by a short horizontal stub, and a slanting line running from the step down to the lower end of the vertical line.
2. In option (C) this is traced on the right-hand side: the right border is the vertical line, the small box and the square give the step and the stub, and the descending diagonal gives the slanting line.
3. In the other options the stepped part lies on the wrong side of the vertical line or the diagonal slopes the other way.

Trick: Match a distinctive part first (here the slant meeting the vertical line), then trace the rest.

Answer: (C) the third figure

Concept: Find the shift applied to each letter position.

1. MOBILE → NQEMQK: M$+1$, O$+2$, B$+3$, I$+4$, L$+5$, E$+6$.
2. BISHOP → CKVLTV follows the same $+1$ to $+6$ shifts ✓.
3. CHARGE: C$+1$=D, H$+2$=J, A$+3$=D, R$+4$=V, G$+5$=L, E$+6$=K ⇒ DJDVLK.

Trick: Shifts +1, +2, +3, +4, +5, +6 by position; option (D) swaps the last two letters, option (B) has W.

Answer: (C) DJDVLK

Concept: Arrange words letter by letter; all begin with 'War', so compare from the 4th letter.

1. 4th letters: Ward-en, Ward-robe (d), Ware-house (e), Warf-are (f), Warr-ant (r), Wars-hip (s).
2. Warden vs Wardrobe: 5th letters e < r, so Warden first.
3. Order: Warden, Wardrobe, Warehouse, Warfare, Warrant, Warship = 2, 4, 1, 6, 5, 3.

Trick: Strip the common prefix 'War' and compare d, d, e, f, r, s.

Answer: (B) 2, 4, 1, 6, 5, 3

Concept: Decide which class lies inside another and which classes are unrelated.

1. Every shirt is a type of clothing → Shirts circle lies inside Clothes.
2. Shoes are footwear, not clothes and not shirts → a separate circle.
3. Figure: one circle inside a bigger circle, plus a separate circle.

Trick: 'Is a type of' → inside; no common member → separate.

Answer: (B) the second figure

Concept: Each fold line acts as a mirror; opening the folds reflects every cut across those lines.

1. Fold 1: right half onto left (vertical diagonal); fold 2: top onto bottom (horizontal diagonal). Cuts (triangle, square, circle) lie in the lower-left quarter.
2. Opening fold 2 reflects them upward: the circle appears near the top, the triangle flips, the square stays next to the centre line.
3. Opening fold 1 reflects the left half to the right, so the right side is an exact mirror of the left.
4. Option (D) is symmetric about both diagonals with squares nearer the centre and triangles toward the outer corners.

Trick: Check left–right mirror symmetry first; option (B) has the right side merely copied, not mirrored.

Answer: (D) the fourth figure

Concept: Replace letters by signs and apply BODMAS (÷, × before +, −).

1. A = +, B = ×, C = −, D = ÷.
2. $11\times 12-144÷24+57$
3. $=132-6+57=183$.

Trick: Do × and ÷ first: 132 and 6, then simply $132-6+57$.

Answer: (B) 183

Concept: Decode each symbol and build a family tree.

1. D * V: D is the daughter of V (D is female).
2. V + B: V is the husband of B.
3. B × U: B is the mother of U.
4. So D and U are children of the same couple V–B; D, being a daughter, is U's sister.

Trick: Read the chain left to right and mark gender at each step (daughter → female).

Answer: (A) Sister

Concept: Place every point on a grid with S as origin and read the final direction.

1. Q is east of S: S(0, 0), Q(2, 0). E is south of S.
2. T is south-east of Q, e.g. T(3, −1); P is north-east of Q and north of T, e.g. P(3, 1).
3. From T, S lies to the left (west) and above (north).

Trick: Whatever distances you take, T is east and south of S, so S is always north-west of T.

Answer: (D) North-west

Concept: Relate the number code to the length of the word.

1. SPAM has 4 letters: $4\times 9=36$ ✓.
2. JUG has 3 letters: $3\times 9=27$ ✓.
3. FROCK has 5 letters: $5\times 9=45$.

Trick: When codes are multiples of a fixed number, divide by the letter count.

Answer: (B) 45

Concept: The given figure must be found inside an option with the same size and orientation (rotation not allowed).

1. Key parts: a line slanting down-left at the left end, a short horizontal segment, a short slant and vertical step upward, and a long line slanting down to the right.
2. In option (A) this zig-zag is traced in the central cluster: the step lines of the shaded block join the long right-downward diagonal.
3. Options (B), (C) and (D) do not contain the long down-right slant attached to the step in this orientation.

Trick: Locate the longest line of the figure (the down-right slant) first, then check the small step at its upper end.

Answer: (A) the first figure

Concept: Write the gaps between consecutive letters of each cluster.

1. SRWX: S$-1$=R, R$+5$=W, W$+1$=X → (−1, +5, +1).
2. HGLM: (−1, +5, +1); POTU: (−1, +5, +1).
3. DBGH: D$-2$=B, B$+5$=G, G$+1$=H → (−2, +5, +1) – different.

Trick: Only the first gap differs, so compare the first two letters: SR, HG, PO are consecutive, DB is not.

Answer: (D) DBGH
