Q&A: practice questions with answers

Concept: Pair each SI unit with the physical quantity it measures.

1. Hertz (Hz) measures frequency → unit : quantity.
2. Newton (N) measures force; $1\text{N}=1\text{kg}·{\text{m/s}}^2$.
3. Power uses watt, pressure uses pascal, temperature uses kelvin – so these are out.

Trick: Read the pair as 'X is the unit of Y' and test each option in that sentence.

Answer: (D) Force

Concept: Letters move forward by a fixed gap, both inside a cluster and between clusters.

1. Inside a cluster: L(12) → Q(17) → V(22): each +5.
2. First letters: L, Q, V, A, next = A+5 = F.
3. Cluster: F → K → P (wrapping after Z where needed).

Trick: Each new cluster = previous cluster minus its first letter plus one new letter (+5): AFK → FK + P.

Answer: (C) FKP

Concept: When first differences grow steadily, check the difference of differences.

1. Differences: 66−40 = 26, 100−66 = 34, 142−100 = 42, 192−142 = 50.
2. They increase by 8 each time, so next difference = 58.
3. 192 + 58 = 250.

Trick: Last digits check: differences end 6,4,2,0 → next ends in 8, so answer ends in 0 → only 250 fits.

Answer: (A) 250

Concept: Track the 1st, 2nd and 3rd letters of each cluster separately.

1. 1st letters S, U, W → +2 each → Y (then A ✓).
2. 2nd letters D, G, J → +3 each → M (then P ✓).
3. 3rd letters F, L, R → +6 each → X (then D after Z ✓).

Trick: Only one option begins with Y – first-letter check alone gives the answer.

Answer: (D) YMX

Concept: Each term is a fixed fraction of the previous one (geometric series).

1. $64÷80=0.8$ and $51.2÷64=0.8$ → ratio $0.8=\frac{4}{5}$.
2. Next $=40.96\times 0.8$.
3. $40.96\times 0.8=32.768$.

Trick: Multiply by 0.8 = subtract 20%: $40.96-8.192=32.768$.

Answer: (A) 32.768

Concept: An assumption is what the speaker must take for granted to make the decision.

1. Spending on renewables 'to ensure' sustainability presumes renewables help sustainability → I implicit.
2. Choosing to 'increase' investment presumes the present amount falls short → II implicit.
3. Availability of funds is not part of the decision's logic; a plan can be announced first and financed later → III not implicit.

Trick: Ask: 'If this assumption were false, would the decision make no sense?' Yes for I and II, no for III.

Answer: (A) Only I and II are implicit

Concept: The copy must match every word, abbreviation and digit.

1. (A) uses short forms Bldg., Sec-19, Rd. → mismatch.
2. (C) PIN 421001 and (D) PIN 421310 → digits differ.
3. (B) agrees character by character.

Trick: Compare the PIN code first – it removes two options in one look.

Answer: (B) Flat No. 18B, Building 15, Sector 19, Dayal Road, Kalyan, Maharashtra - 421301

Concept: Pick letters by position, then try to form valid four-letter words.

1. SHOPPING → 1st S, 2nd H, 3rd O, 6th I.
2. Letters: S, H, O, I.
3. Arrangements like SHOI, HOIS, OHIS are not standard English words → none.

Trick: Count positions carefully (P repeats) – the 6th letter is I, not P; then test endings like -ISH/-OSH, which need two S/H.

Answer: (A) None

Concept: Sort the letters, locate the asked positions, then count letters between them in A–Z.

1. COLLEAGUE sorted: ACEEGLLOU (9 letters).
2. 2nd from left = C; 3rd from right = L (U, O, L).
3. Between C(3) and L(12): 12 − 3 − 1 = 8 letters (D to K).

Trick: Letters between positions p and q = q − p − 1.

Answer: (C) Eight

Concept: Find the shift for each letter position in the first pair and apply it to the second.

1. T→U, U→V, P→U, O→P, F→G: shifts +1, +1, +5, +1, +1.
2. Apply to QBQFS: Q→R, B→C, Q→V (the +5 slot), F→G, S→T.
3. Code = RCVGT.

Trick: All options except one fail the first-letter test (Q+1 = R) and the 2nd letter C confirms it.

Answer: (A) RCVGT

Concept: Convert both positions to the same side, then subtract.

1. Nisha from left = 80 − 25 + 1 = 56th.
2. Mahi = 30th from left.
3. Between = 56 − 30 − 1 = 25.

Trick: Between (no overlap) = Total − (left rank + right rank) = 80 − 55 = 25.

Answer: (B) 25

Concept: Count words from the left.

1. 1st Learning, 2nd new, 3rd skills, 4th improves, 5th confidence.
2. 3rd word = skills.

Trick: Count words, not letters – a common slip under time pressure.

Answer: (C) Skills

Concept: The string is a repeating block; find the block and fill the gaps.

1. Try the block 'rstuq' (length 5).
2. Filled string: rstuq | rstuq | rstuq.
3. Blanks in order: s, q, t, r, q.

Trick: Spot the block length from known letters: 'r … t u' and 'r s … u q' → 5-letter cycle.

Answer: (A) s, q, t, r, q

Concept: Accept only what the statement directly guarantees.

1. Library opens at 9 AM → issuing at 8:30 AM is not possible → I false.
2. Closing time is 4 PM → entry after 4 PM is not possible → II follows.

Trick: Check each conclusion against the time window 9 AM–4 PM; anything outside it is ruled out.

Answer: (B) Only Conclusion II follows

Concept: Put each option's signs in and evaluate with BODMAS.

1. Option D: $99÷11+28$.
2. $99÷11=9$; $9+28=37$ ✓.
3. Others: $99-11\times 28$ is negative; $99+11÷28$ is not an integer; $99\times 11+28$ is huge.

Trick: 99 and 11 hint at division ($99÷11=9$); $37-28=9$ confirms.

Answer: (D) ÷ and +

Concept: Children of the same couple are siblings.

1. P–Q couple; R is P's son, so Q's child too.
2. Q is S's mother → S is also a child of the couple.
3. T is R's sister → T is a daughter of P–Q → sister of S.

Trick: U (P's brother) is an uncle and Q is the mother – both cannot be sister of S.

Answer: (A) T

Concept: The code starts with the standard two-letter State/UT initials.

1. Rajasthan → RJ.
2. MH = Maharashtra, GJ = Gujarat, CH = Chandigarh.
3. So RJ19021 belongs to Rajasthan.

Trick: These are the same letters used on vehicle number plates (UP, RJ, MH…).

Answer: (B) RJ19021

Concept: Fix definite positions first, then place the rest.

1. X = 4, T just above → T = 5.
2. Two between X and W → W = 1 or 7; V is above W and below T → W = 1.
3. V below 5 and above 1 with Y directly under V → V = 3, Y = 2.

Trick: W at 7 is impossible because someone (V) must be above W but below T(5).

Answer: (A) Y

Concept: A subset of a set cannot share members with a group disjoint from that set.

1. Mangoes ⊂ Bananas; Bananas and Yellow have nothing in common → No mango is yellow → II follows.
2. Tomatoes contain all yellows but may also overlap bananas/mangoes → 'No mango is tomato' is not definite → I fails.

Trick: 'No' conclusions about a third set (tomato) linked only through 'All yellow are tomato' never follow definitely.

Answer: (B) Only II follows

Concept: Best action corrects the problem while respecting the person.

1. Talking privately finds the cause (transport, workload, health) and sets expectations.
2. Ignoring lets it continue; public scolding hurts morale; cutting duties punishes without knowing the reason.

Trick: In situation questions, prefer the option that is calm, private and solution-oriented.

Answer: (C) Discuss the issue privately and understand the reason
