Q&A: practice questions with answers

Concept: 'Influence' = the power to affect people or events.

1. In the passage, Sweden has gained leadership and influence — i.e. power to shape others.
2. Impact = a strong effect → closest meaning.
3. Weakness, silence and confusion do not match.

Trick: Replace the word in the sentence: 'a status of leadership and impact' still makes sense — the others don't.

Answer: (B) Impact

Concept: 'Dedication' = devoting oneself wholly to a purpose.

1. The passage shows Swedes value nature above convenience from childhood — steady devotion.
2. So dedication = devoted commitment.
3. Dislike and indifference are opposites; lack of knowledge is unrelated.

Trick: Tone check: the passage praises Sweden, so the word must be positive — only (C) is positive.

Answer: (C) Devoted commitment

Concept: The main idea must sum up all paragraphs, not a single detail.

1. Para 1: nature-love is part of Swedish upbringing. Para 2: shown in daily habits and government spending. Para 3: brings success and global standing.
2. Common thread: environmental care is rooted in culture and benefits society → (B).
3. (A) and (D) contradict the text; (C) is opposite to 'enjoy the outdoors'.

Trick: Eliminate options that are false per the passage first; the broad, positive summary left is the main idea.

Answer: (B) Environmental care is deeply rooted in Swedish culture and benefits their society

Concept: Overt = open, done publicly.

1. Opposite = secret, done stealthily → surreptitious.
2. Evident and palpable = clearly seen/felt (similar to overt).
3. Broad = wide — unrelated.

Trick: Overt ↔ Covert. 'Surreptitious' is a synonym of covert, hence the antonym of overt.

Answer: (C) Surreptitious

Concept: Fragrant = having a sweet, pleasant smell.

1. Opposite = foul-smelling → noisome (offensive, stinking).
2. Alluring (attractive), pleasant, luscious (rich, tasty) are all positive.

Trick: Only one option is negative in sense — the antonym of a positive word must be negative.

Answer: (A) Noisome

Concept: When terms roughly triple each time, test a '×n ± k' pattern.

1. $7\times 3+1=22$; $22\times 3+1=67$; $67\times 3+1=202$.
2. Next = $202\times 3+1=606+1=$ 607.

Trick: Divide a term by the previous one: $\frac{202}{67}\approx 3$ → only 607 is just above $202\times 3=606$.

Answer: (A) 607

Concept: When the front person's rank is from the front and the back person's rank from the back (no overlap), total = sum of ranks + people between.

1. Ravi + those ahead of him = 12.
2. People between = 4; Mohit + those behind him = 14.
3. Total = 12 + 4 + 14 = 30.

Trick: No overlap case → just add all three numbers.

Answer: (A) 30

Concept: If one person's position is known from both ends, total = front rank + back rank − 1.

1. Manoj is ahead of Amit (11th from front) with 5 between → Manoj = 11 − 5 − 1 = 5th from front.
2. Manoj is 17th from back.
3. Total = 5 + 17 − 1 = 21.

Trick: Quick check: 11 + 17 = 28 overshoots, so the ranks overlap — subtract (gap + 2): 28 − 7 = 21.

Answer: (A) 21

Concept: Find the hidden operation from the solved examples and apply it.

1. 124 and 25: $(124-25)÷3=99÷3=33$ ✓.
2. 121 and 61: $(121-61)÷3=60÷3=20$ ✓.
3. 172 and 46: $(172-46)÷3=126÷3=$ 42.

Trick: Result much smaller than both numbers → try difference first, then look for a common divisor.

Answer: (A) 42

Concept: A result far bigger than the numbers suggests multiplication.

1. $19\times 27=513$; $3078÷513=6$ → rule: $a\times b\times 6$.
2. Check: $38\times 49=1862$; $1862\times 6=11172$ ✓.
3. $3\times 50\times 6$ = 900.

Trick: $3\times 50\times 6$ must be a multiple of 100 here — only 900 among the options.

Answer: (B) 900

Concept: Terms close to perfect cubes → compare with $n^3$.

1. ${11}^3=1331$ → 1321 (−10); ${12}^3=1728$ → 1718; ${13}^3=2197$ → 2187; ${14}^3=2744$ → 2734.
2. Next: ${15}^3-10=3375-10=$ 3365.

Trick: Learn cubes 1–20: 1331, 1728, 2197, 2744, 3375 spot such series instantly. 3375 itself is a trap option.

Answer: (D) 3365

Concept: Each fold doubles the layers; opening a fold mirrors the holes across the fold line.

1. 2 folds → $2^2=4$ layers, so every punch gives 4 holes; 3 punches → 12 holes.
2. Open the vertical fold: holes reflect left ↔ right across the centre line.
3. Open the horizontal fold: the upper half reflects into the lower half. The symmetric pattern matches option (C).

Trick: Count first: the right option must show exactly 12 holes (8 square + 4 round) arranged symmetrically about both centre lines.

Answer: (C) Option (C)

Concept: n folds → $2^n$ layers; unfolding mirrors the marks across each fold line in reverse order.

1. 3 folds → $2^3=8$ layers; 2 punches → 16 marks.
2. Undoing the two vertical folds makes 4 identical columns (a left-right flip keeps the up-down order of the two marks).
3. Undoing the horizontal fold flips the order in the lower half (tall mark above wide mark) → option (C).

Trick: Left-right mirroring never swaps top and bottom; only the horizontal fold does — use this to eliminate options.

Answer: (C) Option (C)

Concept: Check consecutive differences.

1. Differences: 9, 11, 13, 15 → increasing odd numbers.
2. Next difference = 17 → $60+17$ = 77.

Trick: Also $n^2-4$ for n = 4, 5, 6…: $9^2-4=81-4=77$.

Answer: (A) 77

Concept: Find one rule linking the four cells of each box.

1. Box 1: $\text{top-right}\times \text{bottom-left}+\text{top-left}=4\times 3+5=17$ ✓.
2. Box 2: $5\times 2+6=16$ ✓.
3. Box 3: $?\times 3+4=19$ → $?\times 3=15$ → ? = 5.

Trick: Bottom-right is the largest number, so treat it as the result and build it from the other three.

Answer: (C) 5

Concept: Count systematically, group by group, so no triangle is missed or repeated.

1. Triangles using the top apex: 8 (small ones at the top edge, the big ones resting on the bottom side, and two formed with the vertical line).
2. Triangles using the bottom apex (not already counted): 6.
3. Left half (with side AD and the inner crossing): 5; right half by symmetry: 5.
4. Total = 8 + 6 + 5 + 5 = 24.

Trick: Use symmetry: the figure is symmetric left-right, so count one half carefully and double it.

Answer: (B) 24

Concept: 'Only A and B' = the region common to A and B but outside the third figure.

1. Balls (rectangle) ∩ tables (circle), outside triangle = 10 → Statement I true.
2. Total bats (triangle) = 11 + 8 + 7 + 12 = 38.
3. Total balls (rectangle) = 13 + 10 + 8 + 11 = 42 → difference 4, not 14 → Statement II false.

Trick: For totals, add every number lying inside that shape's boundary — including shared regions.

Answer: (A) Only I

Concept: Facing the centre, 'right' means moving anticlockwise.

1. Place S; 2 seats to its right → Q; 2 more to the right → P.
2. Empty seats: next to S (on its right) and between Q and P.
3. R cannot sit beside P → R sits immediately right of S; T is between Q and P.
4. Going right from S: R, Q, T → T is 3rd.

Trick: In a circle of 5, 3rd to the right = 2nd to the left — quicker to check.

Answer: (C) T

Concept: Find Y's position from the left, then use 'second from one end'.

1. Y is 8 + 5 + 1 = 14th or 8 − 5 − 1 = 2nd from the left.
2. If Y were 2nd from left, the row size could not be fixed — so Y is 14th from left and 2nd from the right end.
3. Total = 14 + 2 − 1 = 15.

Trick: Pick the case that gives a unique answer — a valid exam question always has one.

Answer: (A) 15

Concept: Apply both changes seen in the first pair to the third figure.

1. Pair 1: hexagon (6 sides) → pentagon (5 sides): one side less.
2. The inverted letter inside becomes upright (180° turn).
3. Third figure: octagon with inverted P → heptagon (7 sides) with upright P = option (B).

Trick: Count sides first to drop options, then check the letter's orientation.

Answer: (B) Option (B)
