Q&A: practice questions with answers

Concept: Passive 'will have been + V3' → active 'will have + V3'.

1. The doer (the diligent student) becomes the subject.
2. 'will have been submitted' → 'will have submitted'.
3. So the active verb is will have submitted, with 'his final thesis' as object.

Trick: Just drop 'been' – future perfect stays future perfect. A, B, D change the tense.

Answer: (C) The diligent student will have submitted his final thesis by the end of the semester.

Concept: Active 'modal + have + V3' → passive 'modal + have been + V3'.

1. Object 'the staff' becomes the subject.
2. 'should have warned' → 'should have been warned'.
3. Doer goes after 'by': …by the manager.

Trick: Passive always needs 'be/been + V3'; C has V-ing and D lacks 'been'.

Answer: (B) The staff should have been warned about the changes in the schedule by the manager.

Concept: Reverse the indirect changes: tense goes forward, pronouns return to the speaker's view.

1. 'told the staff that' → said, "…".
2. Past perfect 'had been seen' → present perfect 'have been seen'.
3. 'their' (the staff's) → 'your', as the director speaks to them.

Trick: Direct speech to listeners uses 'you/your'; options with 'their' or 'had' are out.

Answer: (B) The director said, "Your creative input and loyalty have been seen and admired."

Concept: 'asked if' signals a yes/no question; reverse pronoun, time and tense shifts.

1. he → you, she → I, that day → today.
2. 'Would … have been able' is a conditional modal – it stays as it is.
3. 'had been a very subtle hint' → 'was a very subtle hint'.

Trick: Check 'today': it removes C; 'Will' in B and 'Could you solve' in D break the conditional.

Answer: (A) "Would you have been able to solve the puzzle today if I had not given you the clue, which was a very subtle hint?' she asked him.

Concept: Arrange actions in the order they happen.

1. P: choose a sunny spot and dig a hole – first step.
2. S: 'Before placing the sapling inside' – refers to that hole.
3. R: position the plant and fill soil; Q: the tree stands tall – final result.

Trick: Find the opener (P) and the result (Q); only option B starts with P and ends with Q.

Answer: (B) P, S, R, Q

Concept: Best response meets both goals: business survival and Rohit's independence.

1. Partnership solves the cost problem, but full control would cost his independence.
2. Negotiating lets him share control only where needed and keep core decisions.
3. A and D lose the business; B gives away all control.

Trick: In judgement questions, pick the balanced middle path – avoid extremes (reject all / accept all / shut down).

Answer: (C) Negotiate terms to share control while protecting core interests

Concept: Solve a one-sided work arrangement professionally, without conflict.

1. The problem: helping has started hurting your own deadlines.
2. Clearly stating limits and agreeing on fair sharing fixes the cause.
3. A creates public conflict, B harms teamwork, D lets the issue grow.

Trick: Right answer = calm, direct communication; wrong ones = complaining, avoiding, or silently suffering.

Answer: (C) Communicate boundaries clearly and discuss fair sharing of responsibilities

Concept: Position from left = Total − position from right + 1.

1. A = 10th from left.
2. B from left = 40 − 15 + 1 = 26th.
3. Cars between = 26 − 10 − 1 = 15.

Trick: Between = Total − (left rank + right rank) = 40 − (10 + 15) = 15 (works when they don't overlap).

Answer: (B) 15

Concept: A valid course of action is practical and targets the cause (overspeeding).

1. I: banning all vehicles is extreme and unrealistic – does not follow.
2. II: stricter rules + driver awareness directly control speeding – follows.

Trick: Words like 'ban all', 'immediately', 'completely' usually make a course of action invalid.

Answer: (B) Only II follows

Concept: Convert letters to alphabet positions and find the gap.

1. F=6, I=9, L=12, O=15 → each +3.
2. Next = 15 + 3 = 18 = R.

Trick: Use EJOTY (5, 10, 15, 20, 25): O = 15, so 18 = R.

Answer: (D) R

Concept: The first step must act directly on the problem – shortage of water.

1. Conservation cuts wastage; repairing pipelines stops leakage.
2. Both increase usable water quickly, serving the public.
3. Festival, decorative trees and shopping centres do nothing for water supply.

Trick: Match the solution to the problem keyword ('water') – only B mentions it.

Answer: (B) Implement water conservation measures and repair pipelines

Concept: A word can be formed only if each letter is available (in enough count).

1. INSPIRATION letters: I×3, N×2, S, P×1, R, A, T, O.
2. STAR, PAIN, RAIN – all letters available.
3. PIPE needs two P's and an E – there is one P and no E.

Trick: First scan for a letter not present at all – 'E' instantly removes PIPE.

Answer: (D) PIPE

Concept: A vertical mirror (AB on the right) swaps left and right; top and bottom stay the same.

1. Circles in the upper-right part move to the upper-left part.
2. Small triangles in the upper-left move to the upper-right.
3. Horizontal lines (upper right) go to upper left; vertical lines (lower left) go to lower right; slanting lines (lower right) go to lower left and their slope reverses.

Trick: Track 2–3 distinctive elements (circles, triangles) and their side – one mismatch eliminates an option.

Answer: (B) Option figure B

Concept: With limited money, spend first where the need is greatest.

1. A survey of students and staff shows which areas are most urgent.
2. Funds can then go by priority, giving maximum benefit.
3. A is biased, B avoids the decision, C spreads money too thin.

Trick: 'Identify priorities first' is the standard logical first step in budget questions.

Answer: (D) Conduct a survey to identify priority areas and allocate based on importance

Concept: Repeated, identical questions are best handled by self-service information.

1. A FAQ page answers common questions on hours and availability.
2. An automated system gives instant, up-to-date answers and frees staff.
3. Closing, ignoring or penalising doesn't meet the users' genuine need.

Trick: 'Most efficient' + 'repeated' → think automation / FAQ.

Answer: (D) Introduce a FAQ page and an automated information system

Concept: Find how each letter moves from the first pair to the second.

1. A(1)→E(5), D(4)→H(8): each +4.
2. J(10)+4 = 14 = N; M(13)+4 = 17 = Q.
3. Answer pair: NQ.

Trick: Inside each pair the gap is +3 (A→D, E→H, J→M); so the answer must also have gap +3: N→Q.

Answer: (B) NQ

Concept: When first differences are unequal, check differences of differences.

1. First differences: 271, 331, 397.
2. Second differences: 60, 66 → next 72.
3. Next first difference = 397 + 72 = 469.
4. Next term = 1619 + 469 = 2088.

Trick: Last digits check: 1619 + …69 ends in 8 → only 2088 fits.

Answer: (D) 2088

Concept: Find the rule shared by three pairs.

1. 49, 64 = $7^2,8^2$; 121, 144 = ${11}^2,{12}^2$; 36, 49 = $6^2,7^2$.
2. Rule: squares of two consecutive numbers.
3. 15 and 22 are not perfect squares – odd one.

Trick: Know squares 1–30 by heart; non-squares are spotted instantly.

Answer: (B) 15,22

Concept: Replace symbols with real signs, then apply BODMAS.

1. * = ÷, $ = +, # = −: $14÷28+8-24$.
2. $14÷28=\frac{1}{2}$.
3. $\frac{1}{2}+8-24=\frac{1}{2}-16=-\frac{31}{2}(=-15.5)$.

Trick: Answer must be $-16+\frac{1}{2}$, i.e. $-15\frac{1}{2}=-\frac{31}{2}$.

Answer: (B) $\frac{-31}{2}$

Concept: Unfold step by step; each unfold mirrors the punches across the fold line.

1. Three folds → 8 layers; 2 punches × 8 = 16 holes.
2. Undoing the two vertical folds repeats the pair (wide mark above tall mark) across 4 columns in the upper half.
3. Undoing the first (horizontal) fold mirrors it into the lower half: tall mark above wide mark.

Trick: Count holes first (16), then check order: top half wide-over-tall, bottom half tall-over-wide.

Answer: (C) Option figure C
