Q&A: practice questions with answers

Concept: has/have + V3 = Present Perfect.

1. 'has gained' = has + past participle.
2. Simple present would be 'gains'; continuous 'is gaining'; simple past 'gained'.

Trick: See 'has/have' + V3 → Present Perfect, no further thinking.

Answer: (B) Present Perfect

Concept: Simple present passive: is/are + V3 + by + agent.

1. New subject 'The benefits…' is plural → 'are'.
2. highlight → are highlighted by health professionals.
3. (B) wrong tense, (D) wrong number, (A) roles reversed.

Trick: Subject-verb agreement: head noun 'benefits' (plural) → 'are'.

Answer: (C) The benefits of regular physical activity are highlighted by health professionals.

Concept: Sedentary = involving much sitting, little movement.

1. Passage links it with screen time and lack of exercise.
2. So it means inactive; Active, Energetic, Restless are opposite.

Trick: Sedentary ~ 'sedan' (sit) → sitting job/life.

Answer: (C) Inactive

Concept: Consistent = regular, steady.

1. Opposite = happening irregularly, now and then → Sporadic.
2. Regular, Steady, Persistent are synonyms of consistent.

Trick: Three options mean the same thing – the odd one out is the antonym.

Answer: (C) Sporadic

Concept: Locate the line on institutions in the last paragraph.

1. Passage: institutions create supportive environments, organise sports and encourage balanced routines.
2. Option (B) matches; others contradict the passage.

Trick: Negative-sounding options (limiting, increasing workload, discouraging) go against the passage's tone.

Answer: (B) By organising activities and supporting balanced routines

Concept: When sum and difference of two ages are known: smaller = $\frac{\text{sum}-\text{difference}}{2}$.

1. Sum = 45, difference = 15.
2. B (younger) = $\frac{45-15}{2}=\frac{30}{2}=15$ years.
3. Check: A = 30; $30+15=45$ ✓

Trick: Smaller = $\frac{S-D}{2}$, Larger = $\frac{S+D}{2}$ – no equation needed.

Answer: (A) 15 years

Concept: $\text{SI}=\frac{P\times R\times T}{100}$.

1. P = ₹6000, R = 10%, T = 4 years.
2. $\text{SI}=\frac{6000\times 10\times 4}{100}=60\times 40=$ ₹2400.

Trick: 10% of 6000 = 600 per year; × 4 years = 2400.

Answer: (B) ₹2400

Concept: Each right turn = 90° clockwise.

1. Start: North.
2. Right turn → East (walks 5 km).
3. Right again → South (walks 7 km) – still facing South.

Trick: Two right turns = 180° → opposite of start: North → South.

Answer: (B) South

Concept: Opposite movements cancel; find net displacement.

1. East 20 and West 20 cancel → 0 horizontally.
2. Only North 20 km remains.
3. Distance from start = 20 km.

Trick: Cancel equal opposite legs first; whatever is left is the answer.

Answer: (C) 20 km

Concept: Best action = honest, prompt and solution-oriented.

1. A submitted report with an error can mislead the client.
2. Telling the senior at once and proposing a fix owns the mistake and limits damage.
3. Ignoring, waiting or blaming others is unethical/unprofessional.

Trick: In such questions pick the option showing honesty + responsibility + action.

Answer: (C) Inform your senior immediately and suggest a correction

Concept: Find the place-value change for each letter.

1. P(16) → C(3), R(18) → E(5), S(19) → F(6): each −13 (same as +13).
2. H(8) + 13 = 21 = U; S(19) − 13 = 6 = F; T(20) − 13 = 7 = G.
3. HST → UFG.

Trick: ±13 = opposite letter pairs: A–N, B–O, C–P … H–U, S–F, T–G.

Answer: (B) UFG

Concept: A, E, I, O, U – take the next vowel.

1. A → next vowel E.
2. O → next vowel U.

Trick: Vowels in order: A E I O U – just step one forward.

Answer: (B) U

Concept: Break the long string into 4-digit groups.

1. 200220122022 → 2002, 2012, 2022.
2. Each increases by 10.
3. Next = 2022 + 10 = 2032.

Trick: Options are 4-digit numbers – so cut the string in 4-digit pieces.

Answer: (B) 2032

Concept: Match spelling, numbers and punctuation character by character.

1. (B) 'C.E.' has extra full stops.
2. (C) 'Citi' – spelling changed.
3. (D) 'Februry' – letter 'a' missing. Only (A) matches.

Trick: Check in chunks: name → date → month → era; drop an option at the first mismatch.

Answer: (A) Mexico City: 14th February, 1929 CE.

Concept: Compare every character; pick the closest copy as per the key.

1. (B) 'Accr_a' – stray underscore.
2. (C) 'Jun.' – extra full stop.
3. (D) year changed to 1972.
4. (A) has no wrong letter or number (only the space after the comma is missing), so it is the keyed match.

Yaad rakhein: Eliminate options with changed letters/numbers first – the one left is the answer.

Answer: (A) Accra (PG): Jun 5,1952.

Concept: The given shape must appear in the option in the same size and tilt (no rotation).

1. Key feature: a quadrilateral with a sharp top peak, a long right side and a long sloping base.
2. Option (A) contains exactly these four lines in the same orientation.
3. In (B), (C), (D) the matching part is blunt or lacks the long sloping base.

Trick: Trace the most distinctive line (the long slanted base) first – it rejects options quickly.

Answer: (A)

Concept: Every line of the question figure must be traceable in the option without turning.

1. Key feature: two long slanting lines crossing each other with a full-height vertical between them.
2. Option (C) has all these lines in place.
3. (A) – a slant stops early; (B) – vertical is short; (D) – one crossing line is missing.

Trick: Check the crossing point and the full vertical – only one option keeps both.

Answer: (C)

Concept: Bottom number = $\text{product of the three numbers above}\times 10$.

1. Col 1: $15\times 3\times 6=270\to 2700$ ✓
2. Col 2: $7\times 9\times 5=315\to 3150$ ✓
3. Col 3: $9\times 6\times 5=270\to 2700$.

Trick: Results ending in '00'/'50' hint at '× 10' after a product.

Answer: (C) 2700

Concept: Count by sections using the centre point; use symmetry.

1. Upper line has 5 points all joined to the centre → 5C2 = 10 triangles.
2. Top tip with 3 points on that line → 3C2 = 3; tip–centre–petal corner → 2. Upper total = 15.
3. Lower half by symmetry = 15.
4. Left tip and right tip make 2 each with the centre → 4. Total = 15 + 15 + 4 = 34.

Trick: Points on one straight line all joined to a common vertex: triangles = nC2.

Answer: (D) 34

Concept: Fix a pair of horizontal lines; count verticals spanning the whole strip → ${}^k{C}_2$.

1. Top strip: 3 verticals → 3; middle strip: 4 → 6; bottom strip: 3 → 3.
2. Top + middle: 2 → 1; middle + bottom: 3 → 3; whole figure → 1.
3. Total = $3+6+3+1+3+1=17$.

Trick: Rectangles in a strip with k full verticals = $\frac{k(k-1)}{2}$.

Answer: (C) 17
