Q&A: practice questions with answers

Concept: Check every word, spelling and number of the given address against each option.

1. Given parts: Green Towers, Nungambakkam, Karnataka, 560001.
2. (A) has 'Karnatka' – letter 'a' missing.
3. (C) has 'Green Tower' – final 's' missing; (D) has 'Nungambakam' – one 'k' missing.
4. Only (B) matches word for word.

Trick: Compare the long, tricky words first (place names) – most errors hide there.

Answer: (B) Apartment 2B, Green Towers, Nungambakkam, Karnataka, Bangalore - 560001

Concept: Swap the two signs in each option and evaluate with BODMAS until LHS = 74.

1. As given: $75-5+6=76\ne 74$.
2. Try (D) swap + and −: $15\times 5+20÷4-6$.
3. $=75+5-6=74$ ✓

Trick: Present value 76 is just 2 more than 74; flipping +6 to −6 and −5 to +5 changes the total by $-12+10=-2$. Exactly what we need.

Answer: (D) + and −

Concept: Link D and I through common terms; if the result is '≥', the two conclusions '>' and '=' form an either-or pair.

1. From D ≥ E and E = H ≥ I: D ≥ E = H ≥ I.
2. So D ≥ I – D may be greater than or equal to I.
3. Neither I (D > I) nor II (D = I) is definite alone, but together they cover '≥'.

Trick: Same two letters + one conclusion '>' + the other '=' + combined result '≥' → answer is 'Either I or II'.

Answer: (C) Either conclusion I or II is true

Concept: Track generations: child of a son is a grandchild.

1. O → son N (one generation down).
2. N → daughter M (second generation down).
3. M is a female two generations below O → granddaughter.

Trick: Son's/daughter's daughter = granddaughter; count generation steps and check gender.

Answer: (B) Granddaughter

Concept: A valid action is practical and addresses the problem directly.

1. Action 1: an internal audit finds how big the irregularity is – practical first step.
2. Action 2: strict action against the guilty (once identified) prevents repeat fraud.
3. Both are logical steps of the same process: investigate, then punish.

Trick: When one action detects the problem and the other corrects it, both usually follow.

Answer: (C) Both follow

Concept: Pick the response that is helpful, polite and respects the person's consent.

1. Helping patients with forms is part of front-desk work; no policy forbids it – (A) is wrong.
2. Shifting them without reason (B) or ignoring them (D) is careless.
3. (C) offers help politely and acts only after consent – ideal.

Trick: In such questions, the option that is helpful + polite + seeks consent is almost always correct.

Answer: (C) Approach them and politely ask if they need assistance, and if they agree, help them fill out the form.

Concept: Three numbers share a property (prime); find the one that does not.

1. 11, 13, 17 have only two factors (1 and itself) → prime.
2. $15=3\times 5$ → composite.
3. So 15 is the odd one.

Trick: Any odd number ending in 5 (other than 5) is divisible by 5 – never prime.

Answer: (D) 15

Concept: 'Some A are B' + 'No B is C' ⇒ 'Some A are not C'.

1. Some pets are buffaloes, and no buffalo is a cow.
2. So those pets cannot be cows → 'Some pets are not cows' – I follows.
3. Only some buffaloes are pets (hence friendly); the rest are unknown → II does not follow.

Trick: 'Some' never gives an 'All' conclusion – reject II instantly.

Answer: (A) Only I follows

Concept: Convert letters to positions and find the pattern in the gaps.

1. Positions: 3 (C), 6 (F), 10 (J), 15 (O), 21 (U).
2. Steps grow +3, +4, +5, +6, so the next step is +7.
3. 21 + 7 = 28; subtract 26 → 2 → B.

Trick: Positions 3, 6, 10, 15, 21 are triangular numbers; next is 28 → after Z, count 2 more → B.

Answer: (A) B

Concept: Each letter of the answer must be present in the given word (in enough number).

1. APPLE → A, P, P, L, E.
2. PASE needs S, PIPE needs I, PLEN needs N – not available.
3. LEAP = L, E, A, P – all present ✓

Trick: Hunt for one letter not in the base word – it eliminates options in seconds.

Answer: (C) LEAP

Concept: Find the fixed step between consecutive letters.

1. X(24) → V(22) → T(20) → R(18): each −2.
2. 18 − 2 = 16 → P.

Trick: Skip one letter backwards each time: X (w) V (u) T (s) R (q) P.

Answer: (C) P

Concept: Use all given letters exactly once to form a real word.

1. Letters: C, L, E, P, I, N (6 letters).
2. CLEAN and PLACE need 'A' – not given; CLEAP is not a word.
3. P-E-N-C-I-L uses all six → PENCIL.

Trick: Count letters first: only a 6-letter option can use all six letters.

Answer: (C) PENCIL

Concept: Decode the rule from FOLDER → SFEMPG and apply it to DESIGN.

1. FOLDER reversed = REDLOF; each letter +1 → SFEMPG ✓
2. DESIGN reversed = NGISED.
3. +1 each: N→O, G→H, I→J, S→T, E→F, D→E → OHJTFE.

Trick: Last letter R of FOLDER became first letter S (+1) – a quick sign the word is reversed.

Answer: (B) OHJTFE

Concept: Group by function: web-page building vs data storage.

1. HTML gives structure, CSS gives style, JavaScript adds interactivity – all front-end web technologies.
2. MySQL is a relational database management system (stores and queries data).

Yaad rakhein: Remember 'SQL' = Structured Query Language → it belongs to databases, not page design.

Answer: (D) MySQL

Concept: Net work rate = inlet rate − outlet rate; use LCM as total capacity.

1. Capacity = $\text{LCM}(10,15)=30$ units.
2. Inlet = $\frac{30}{10}=3$ units/h; outlet = $\frac{30}{15}=2$ units/h.
3. Net = $3-2=1$ unit/h → time = $\frac{30}{1}=30$ h.

Trick: For fill a h, empty b h: time = $\frac{ab}{b-a}=\frac{10\times 15}{15-10}=\frac{150}{5}=30$ h.

Answer: (A) 30 h

Concept: A health worker must respond promptly and route the person to proper care.

1. Dismissing (B) or delaying (C) can make a serious condition worse.
2. Referring straight to a psychiatrist without any first assessment (D) skips the basic step.
3. Guiding them to the right support and resources (A) is responsible and immediate.

Trick: Reject options that ignore, delay, or skip procedure – the balanced, supportive action remains.

Answer: (A) Guide them to the necessary support and resources

Concept: Apply both swaps of an option, then solve with BODMAS.

1. (B): swap + ↔ × and 8 ↔ 5 → $5\times 4+8$.
2. $=20+8=28$ ✓
3. (A) gives $8\times 5+4=44$; (C) gives $4\times 8+5=37$ – wrong.

Trick: Need a product near 28: $5\times 4=20$, and $20+8=28$ – points straight to swapping 8 and 5.

Answer: (B) + and ×, 8 and 5

Concept: Replace letters with operators, then follow BODMAS.

1. 10 P 2 R 4 Q 2 → $10+2\times 4-2$.
2. Multiply first: $2\times 4=8$.
3. $10+8-2=16$.

Trick: Do × and ÷ before + and −; never solve left to right blindly (that gives 46).

Answer: (B) 16

Concept: Find the differences; if they rise uniformly, continue that pattern.

1. 14−7=7, 24−14=10, 37−24=13, 53−37=16.
2. Differences increase by 3 → next = 19.
3. 53 + 19 = 72.

Trick: Second difference constant (3) → simply add 16 + 3 = 19 to the last term.

Answer: (A) 72

Concept: 'All A are B' can be converted to 'Some B are A'.

1. All buses are rickshaws → Some rickshaws are buses – II follows.
2. Only some cars are buses; 'All cars are buses' cannot be drawn – I fails.

Trick: A 'Some' statement can never produce an 'All' conclusion.

Answer: (A) Only Conclusion II follows
