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

Concept: Rewrite the expression with the new meanings of the signs, then simplify.

1. $75-5+4\times 8\to 75÷5\times 4+8$.
2. $75÷5=15$; $15\times 4=60$.
3. $60+8=68$.

Trick: Write the converted expression on paper first – most mistakes come from swapping signs mentally.

Answer: (A) 68

Concept: Each letter is written as its position number in the alphabet.

1. P = 16, E = 5, N = 14 → PEN = 16-5-14.
2. NEP: N = 14, E = 5, P = 16 → 14-5-16.

Trick: NEP is PEN reversed, so just reverse the code: 16-5-14 → 14-5-16.

Answer: (A) 14-5-16

Concept: Find the shift from TABLE → UBCMF, then apply it again to UBCMF.

1. T→U, A→B, B→C, L→M, E→F: every letter +1.
2. UBCMF +1: U→V, B→C, C→D, M→N, F→G.
3. Code = VCDNG.

Trick: Applying +1 twice = TABLE +2: T+2 = V, E+2 = G – check first and last letters only.

Answer: (A) VCDNG

Concept: Build a family tree from the statements; read 'his' with the latest male mentioned (R).

1. P and Q are a married pair; R is P's brother.
2. Q is daughter-in-law of widow U → U is mother of P and R.
3. 'S is his only son' refers to R; T is S's sister → T is also R's child.
4. So T is R's daughter.

Trick: Check gender words: T is a 'sister', so T is female – a child of R who is female = daughter.

Answer: (B) Daughter

Concept: Pattern: multiply by n and add n (n = 1, 2, 3, 4…).

1. 2 → 3 (×1, +1) ✓; 3 → 8 (×2, +2) ✓; 8 → 27 (×3, +3) ✓
2. Next: 27 → (×4, +4) should give 112.
3. The series has 111 instead, so 111 is the wrong term.

Trick: Whenever ×1, ×2, ×3 shows up, check if the same number is also being added.

Answer: (C) 111
