Q&A: practice questions with answers

Concept: A word that tells 'how' an action is done is an adverb.

1. 'correctly' describes the manner of 'collected and processed' (verbs).
2. Adjective 'correct' + -ly → adverb of manner.
3. It does not describe a noun, link nouns or replace a noun.

Trick: Ask 'How?' – if the word answers it for a verb, it is an adverb.

Answer: (B) Adverb

Concept: Meaning of 'toxic' as used in the passage.

1. The passage links toxic gadgets with damage to health and the ecosystem.
2. Toxic = poisonous, harmful to living things.
3. 'Healthy and safe' is the opposite; the other two are unrelated.

Yaad rakhein: Toxin = poison; detox = removing poison.

Answer: (C) Poisonous or harmful

Concept: Meaning of 'severe' in 'severe damage'.

1. Severe = very serious, intense, harsh.
2. The passage stresses heavy harm to health and environment.
3. 'Mild and gentle' is the antonym; 'easily fixable' and 'beneficial' contradict the context.

Yaad rakhein: Common pairs: severe pain, severe weather, severe punishment – all mean 'very serious'.

Answer: (B) Serious and intense

Concept: A central theme should fit every paragraph, not a single point.

1. Para 1: discarded devices harm health and environment.
2. Para 2: proper recycling methods; Para 3: need for awareness, laws and responsibility.
3. Common thread → recycling e-waste is essential for health and environment.

Trick: Reject extremes ('never', 'only') and statements the passage contradicts (throwing phones in trash).

Answer: (B) E-waste recycling is essential to protect health and environment

Concept: Word for a detailed analysis plus judgement of a work or theory.

1. Critique = a careful evaluation of a literary, philosophical or political work.
2. Summary = brief restatement; Abstract = short overview of a paper; Excerpt = a quoted extract.

Trick: 'Assessment' in the definition = judging → critique (from 'critic').

Answer: (C) Critique

Concept: Ages in ratio: take a common multiplier x; both ages grow by the same years.

1. Now: Anuj = 6x, Brijesh = 7x.
2. After 6 years: Anuj : Brijesh = $(6x+6):(7x+6)=7:8$.
3. Cross-multiply: $49x+42=48x+48$, so $x=48-42=6$.
4. Brijesh = $7\times 6=$ 42 years.

Trick: Ratio 6:7 → 7:8 is a jump of 1 in each term, which took 6 years, so 1 part = 6 → Brijesh = $7\times 6=42$. Or test options: only 42 is a multiple of 7 giving 36:42 → 42:48 = 7:8.

Answer: (B) 42 years

Concept: Best response = empathy + help the person decide calmly, keeping trust intact.

1. The frustration is temporary, so the danger is a hasty decision.
2. Listening calmly shows respect; suggesting they reflect keeps the decision theirs.
3. (A) encourages a rash step, (C) sounds threatening, (D) is gossip and breaks trust.

Trick: In such questions pick the option that is calm, respectful and solution-oriented; drop extreme or negative ones.

Answer: (B) Calmly listen to their reasons and suggest thinking it through before deciding

Concept: Replace the coded symbols, then solve using BODMAS.

1. & = −, ∗ = ×.
2. 7 & 9 ∗ 8 & 6 → $7-9\times 8-6$.
3. Multiply first: $9\times 8=72$.
4. $7-72-6=$ −71.

Trick: Unit digit check: 7 − 2 − 6 ends in …1 (as −71), so only −71 fits.

Answer: (B) -71

Concept: Convert both positions to the same end, then count the gap.

1. B from beginning = 24 − 11 + 1 = 14th.
2. A is 8th from beginning.
3. Chairs between = 14 − 8 − 1 = 5.

Trick: Shortcut: between = total − (left rank + right rank) = 24 − (8 + 11) = 5 (works when positions do not overlap).

Answer: (B) 5

Concept: Use alphabet positions and find the pattern.

1. X = 24, T = 20, P = 16, L = 12.
2. Each step is −4, so next = 12 − 4 = 8.
3. 8th letter = H.

Trick: Remember EJOTY (5, 10, 15, 20, 25) – T = 20 instantly helps place the rest.

Answer: (C) H

Concept: Mirror on a vertical line AB: left and right swap, top and bottom stay.

1. The letters 'R h f g b q' get reversed in order: the letter nearest the mirror (q) appears first.
2. Each letter also flips sideways: q → p, b → d, R → Я, and h, f, g face the opposite way.
3. So the image starts with 'p d' and ends with 'Я' – only option (D) has this with every letter flipped.

Trick: Check just the two ends: first letter should be the flipped last letter (q → p) and last should be flipped R (Я).

Answer: (D) Pd P 7 ત Я

Concept: Unfold step by step: every cut on a fold line is mirrored across that fold.

1. The sheet is folded along a diagonal, then folded again, leaving a triangle whose apex is the centre of the square.
2. The cut at the apex (where both folds meet) opens into one square hole at the centre.
3. Cuts on the slanting fold edges repeat on all four sides, and the circle near the corner side appears as a pair at two opposite corners.
4. This matches option (C).

Trick: Count folds: 2 folds → each punch appears up to 4 times; a cut at the meeting point of folds becomes a single central shape.

Answer: (C)

Concept: Up-down movement suggests two interleaved series.

1. Odd places: 6, 24, 96, 384 → ×4 each time.
2. Even places: 5, 20, ?, 320 → also ×4.
3. ? = $20\times 4=$ 80; check $80\times 4=320$ ✔.

Trick: Check from the end: $320÷4=80$ directly.

Answer: (B) 80

Concept: Split into odd-place and even-place terms.

1. Odd places: 2, 7, 12, 17 → +5.
2. Even places: 7, 13, ?, 25 → +6.
3. ? = 13 + 6 = 19; 19 + 6 = 25 ✔.

Trick: Gap from 13 to 25 is 12 over two steps → 6 each → 19.

Answer: (B) 19

Concept: Compare each letter of the first pair by position change.

1. D(4) → H(8): +4; K(11) → H(8): −3; N(14) → R(18): +4.
2. Apply to OSV: O(15) + 4 = S, S(19) − 3 = P, V(22) + 4 = Z.
3. Answer: SPZ.

Trick: Check only the 2nd letter first: S − 3 = P → options (B)/(C) out; then last letter Z gives SPZ.

Answer: (D) SPZ

Concept: Fast-growing terms near 27, 125, 343… suggest cubes of odd numbers.

1. $28=3^3+1$, $124=5^3-1$, $344=7^3+1$.
2. Next: $9^3-1=729-1=$ 728.
3. Check: ${11}^3+1=1332$, ${13}^3-1=2196$ ✔.

Trick: Know cubes up to 15: 729, 1331, 2197 make such series instant.

Answer: (C) 728

Concept: Correct the behaviour, keep the talent, protect dignity.

1. A private talk avoids humiliation; clear expectations say exactly what must change.
2. Monitoring ensures the improvement lasts.
3. Ignoring (A) rewards rudeness, public criticism (B) embarrasses, sudden removal (D) punishes without warning.

Trick: Management answers usually follow 'private feedback → clear goals → follow-up'.

Answer: (C) Address the behavior privately, set clear expectations, and monitor improvement

Concept: Find the exact question figure (same size, same direction) inside an option.

1. Note the key parts: a short top line, a longer bottom line, two crossing slants (bow-tie) and one slant from the top-right end to the middle of the bottom line.
2. Rotation is not allowed, so this orientation must appear unchanged.
3. Only option (C) contains all these lines in the same position.

Trick: Track the most unusual line (here the extra slant from the top-right) – it eliminates options fastest.

Answer: (C)

Concept: Trace the question figure's chain of strokes inside each option without rotating.

1. The figure is an open zig-zag: tall vertical, short step, shorter vertical, horizontal, short upward slant, final horizontal.
2. The short slant flanked by two horizontals is the rarest part – look for it first.
3. Only option (B) holds the whole chain in the same direction.

Trick: Search for the rare stroke (the slant) first, then confirm the rest around it.

Answer: (B)

Concept: Relate the first three numbers of a row to the last one.

1. Row 1: $(6+5+8)\times 3=19\times 3=57$ ✔.
2. Row 2: $(9+3+4)\times 3=16\times 3=48$ ✔.
3. Row 3: $51÷3=17\to 8+4+?=17\to ?=$ 5.

Trick: 57, 48, 51 are all multiples of 3 – a strong hint that the rule is 'sum × 3'.

Answer: (C) 5
