Q&A: practice questions with answers

Concept: Compare door number, spelling and PIN code part by part.

1. (A) PIN 422002 differs and 'D. No.' has an extra space.
2. (B) door no. reversed to 4-89; PIN has 7 digits.
3. (C) 'Krushna' spelling changed.
4. (D) every part is identical.

Trick: Check the PIN first, then the number, then spellings — most fakes fail at the PIN.

Answer: (D) D.No. 4-98, Krishna Colony, Guntur, Uttar Pradesh - 422001

Concept: Swap the two signs given in each option and solve with BODMAS.

1. Swap − and ÷: $28÷14\times 60-20+8$
2. $28÷14=2$ → $2\times 60=120$
3. $120-20+8=108$ = RHS ✓

Trick: RHS 108 is large, so the × must act on a bigger number — try making $28÷14=2$ first.

Answer: (C) − and ÷

Concept: Replace ÷ by + and + by ÷, then evaluate each with BODMAS.

1. I: $81+9-54\times 9÷27$ → $54\times 9÷27=18$ → $90-18=72$ ✓
2. II: $24+16\times 24÷32-14$ → $16\times 24÷32=12$
3. $24+12-14=22\ne 38$ ✗
4. So only II is wrong.

Trick: Do the ×/÷ block first as one number ($54\times 9÷27=18$), then add/subtract.

Answer: (D) Only II

Concept: Siblings have the same mother.

1. E is the sister of F → E and F are siblings.
2. D is E's mother.
3. So D is F's mother too.

Trick: Gender of F is not needed — mother of one sibling is mother of all.

Answer: (C) Mother

Concept: Father's brother = uncle (chacha).

1. A is a brother → A is male.
2. A, B, C are siblings.
3. C is D's father, so A is D's father's brother → uncle.

Trick: Same generation as the father + male = uncle.

Answer: (D) Uncle

Concept: A valid course of action should be practical and proportionate to the problem.

1. First find and remove the cause of delay — counselling + extra time does this. 1 follows.
2. Suspension is extreme for a first corrective step. 2 does not follow.

Trick: Reject harsh/extreme actions (suspend, ban, dismiss) when a milder fix has not been tried.

Answer: (A) Only 1

Concept: Each letter is paired with its alphabet position.

1. A1, B2, C3, D4, E5 ✓
2. Sixth letter is F, so it should be F6.
3. T is the 20th letter → T6 breaks the pattern.

Trick: Sequence A–I runs in order; spot the letter that jumps out of order (T).

Answer: (C) T6

Concept: 'Some + All' gives 'Some'; then 'No' carries forward to that part.

1. Some pens are paper + all paper are stationery → some pens are stationery → some stationery are pens. II ✓
2. Those pens are stationery, and no stationery is electronic → those pens are not electronic. I ✓

Trick: Some A are B + No B is C → Some A are not C (always valid).

Answer: (C) Both I and II follow

Concept: A new word can use only letters present in the given word.

1. Letters of PREACHER: P, R, E, A, C, H (E and R twice).
2. T, O, U, Q are absent → TEACQ, TOUCH, CQEATE fail.
3. CHAR = C, H, A, R ✓

Trick: Just look for one missing letter (T or Q) — it eliminates three options instantly.

Answer: (C) CHAR

Concept: Words beginning with 'r' take the negative prefix IR-.

1. IR + relevant = irrelevant
2. IR + responsible = irresponsible
3. IR + ritating = irritating — all valid.

Yaad rakhein: Negative prefixes change by first letter: il- before l (illegal), im- before m/p (impossible), ir- before r (irregular).

Answer: (B) IR

Concept: A word common to two sentences takes the code common to both.

1. students: lines 1 & 3 → mi
2. gain: lines 3 & 4 → su; teachers: lines 2 & 4 → da
3. with/care: lines 1 & 2 → lo, pa
4. So 'students gain with teachers' = mi, su, da + (pa or lo) → mi su pa da

Trick: Option must contain mi, su and da — only (C) has all three.

Answer: (C) mi su pa da

Concept: Each position of the cluster moves one letter ahead.

1. 1st: B, C, D, E → F
2. 2nd: S, T, U, V → W
3. 3rd: C, D, E, F → G → FWG

Trick: Check only the middle letter: V+1 = W, which leaves FWG alone.

Answer: (C) FWG

Concept: Group by role: queens/rulers vs. leader-poet.

1. Ahilyabai Holkar – queen of Malwa (Indore).
2. Kittur Chennamma – queen of Kittur (Karnataka); Begum Hazrat Mahal – ruled Awadh in 1857.
3. Sarojini Naidu – poet and Congress leader, never a ruler.

Yaad rakhein: Sarojini Naidu, 'Nightingale of India', was the first woman Governor of an Indian state (UP).

Answer: (D) Sarojini Naidu

Concept: Inside a cluster letters skip one (+2); each new cluster starts one letter later.

1. BDF → CEG → DFH (each letter +1)
2. D+1 = E, F+1 = G, H+1 = I
3. Answer cluster: EGI

Trick: Next cluster starts with E and has the +2 gap: E, G, I.

Answer: (A) EGI

Concept: Successive % changes multiply: price $\times (1-d\%)\times (1+t\%)$.

1. After 25% off: $2400\times \frac{3}{4}=$ ₹1,800
2. VAT 15% of 1800 = ₹270
3. Net = $1800+270=$ ₹2,070

Trick: $2400\times 0.75\times 1.15=1800\times 1.15=2070$ in one line.

Answer: (A) ₹2,070

Concept: Find the hidden rule from the examples: a @ b = 4ab.

1. $8\times 3=24$, and $24\times 4=96$ ✓
2. $7\times 2=14$, and $14\times 4=56$ ✓
3. So 7 @ 1 → $(7\times 1)\times 4=28$

Trick: $96÷24=4$ and $56÷14=4$ — the product of the numbers is always multiplied by 4.

Answer: (C) 28

Concept: In an emergency, the responsible step is to get professional help quickly.

1. Calling ambulance (108/112) and informing traffic police gets the victim help and manages the scene.
2. Ignoring, waiting for others or posting videos does not help the injured.

Yaad rakhein: Under the Good Samaritan rules, a person helping a road-accident victim cannot be harassed by police or hospitals.

Answer: (B) Call emergency services and inform traffic police

Concept: Rewrite with + → ×, × → −, − → +, then apply BODMAS.

1. (A) $5\times 2+6-3=13$ ✓; (B) $7+9-2\times 3=10$ ✓
2. (D) $12-13+7\times 4=-1+28=27$ ✓
3. (C) $7\times 2+4-5=14+4-5=13\ne 25$ ✗

Trick: Start with the option whose RHS looks oddly large (25) — it is usually the wrong one.

Answer: (C) 7 + 2 − 4 × 5 = 25

Concept: Patient care comes before paperwork.

1. Severe abdominal pain may be serious (appendicitis etc.) — needs a doctor at once.
2. Insurance, forms and family contact can be done after treatment starts.

Trick: In any emergency question, the option that saves life/time first is the answer.

Answer: (A) Call the doctor immediately

Concept: Terms are squares of consecutive numbers going down.

1. $144={12}^2$, $121={11}^2$, $100={10}^2$ … $49=7^2$
2. Next = $6^2=36$

Trick: Differences 23, 21, 19, 17, 15 → next 13: $49-13=36$.

Answer: (A) 36
