Q&A: practice questions with answers

Concept: The five English vowels in alphabetical order are A, E, I, O, U.

1. List the vowels left to right: A (1st), E (2nd), I (3rd), O (4th), U (5th).
2. So the 3rd vowel from the left is I.

Trick: Middle vowel of A-E-I-O-U is I – 3rd from either end.

Answer: (C) I

Concept: Compare every part – plot, locality, city, PIN – letter by letter.

1. (A) is missing the word 'No.'
2. (B) has PIN 110022 instead of 110020.
3. (C) has an extra word 'Extn'.
4. (D) is identical in every part.

Trick: Check the PIN code first – it removes the most options in one glance.

Answer: (D) Plot No. 8, Hauz Khas, South Delhi, Delhi - 110020

Concept: The reason (cause) happens first; the result (effect) follows from it.

1. Statement II describes a feature: flexible timing and low cost of online platforms.
2. Statement I describes a trend: more students joining online courses.
3. The features attract students, so II leads to I.

Trick: Ask 'why?' about each statement – 'Why are students enrolling?' is answered by II.

Answer: (B) II is the cause and I is the effect

Concept: The series is a 4-letter block repeated: l m n o.

1. Split into groups of 4: l_no | _mn_ | lm_o.
2. Group 1 needs m (lmno), group 2 needs l at start and o at end (lmno).
3. Group 3 needs n (lmno).
4. Blanks in order: m, l, o, n.

Trick: Spot the block length from the first full letters (l ? n o) and fill each group the same way.

Answer: (A) m, l, o, n

Concept: Terms are squares of even numbers that double each time: 2, 4, 8, …

1. $4=2^2$, $16=4^2$, $64=8^2$.
2. Next should be ${16}^2=256$.
3. $361={19}^2$ – 19 is odd and does not fit.

Trick: Write each term as a square; the odd base (19) is the culprit. Also each term = previous × 4, and $64\times 4=256$, not 361.

Answer: (D) 361

Concept: Replace each symbol by its real meaning, then solve with BODMAS.

1. × → +, ÷ → −, − → ÷, + → ×.
2. Expression: $15+8-2÷2\times 5$.
3. $2÷2=1$; $1\times 5=5$.
4. $15+8-5=18$.

Trick: Rewrite the whole expression first, then do ÷ and × before + and −.

Answer: (B) 18

Concept: Try each pair of swaps and test with BODMAS.

1. Swap + and −: $20+5\times 3÷3-6$.
2. $5\times 3=15$; $15÷3=5$.
3. $20+5-6=19=\text{RHS}$ ✓.

Trick: Here × 3 ÷ 3 cancel, so only ±5 and ±6 matter: $20+5-6=19$ instantly points to swapping + and −.

Answer: (D) + and −

Concept: The roll number starts with the two-letter State code, as RJ = Rajasthan.

1. Maharashtra's standard code is MH.
2. UP = Uttar Pradesh, GJ = Gujarat, CH = Chandigarh.
3. Only MH21987 begins with MH.

Yaad rakhein: These are the same codes used on vehicle number plates (MH, UP, GJ, CH).

Answer: (A) MH21987

Concept: Find the common category; the word outside it is the answer.

1. Banana, litchi and orange are fruits we eat.
2. Rose is a flower, not a fruit.

Trick: Group by 'what is it?' – fruit, fruit, fruit, flower.

Answer: (D) Rose

Concept: Mother's daughter = sister (or self, if the speaker is female).

1. Raj is male, so he cannot be his mother's daughter.
2. Mother's only daughter = Raj's sister.
3. So Sheetal is Raj's sister.

Trick: Read from the end: 'mother's daughter' → sibling who is female → sister.

Answer: (B) Sister

Concept: Parent of a parent is a grandparent.

1. P and Q are husband–wife; R is their son.
2. U is Q's mother, i.e., a parent of R's parent.
3. A female grandparent = grandmother, so U.

Trick: Grandparent = two generations up; follow R → Q → U.

Answer: (D) U

Concept: Each term = sum of the previous two terms.

1. Verify the rule: 5 + 8 gives 13 and 8 + 13 gives 21.
2. First blank = 21 + 13 = 34.
3. Second blank = 34 + 21 = 55.

Trick: Units digit check: 1+3 = 4 → 34, then 1+4 = 5 → 55; only option (A) ends in 4 and 5.

Answer: (A) 34, 55

Concept: Three numbers are perfect squares; find the one that is not.

1. $144={12}^2$, $256={16}^2$, $324={18}^2$.
2. ${18}^2=324$ and ${19}^2=361$, so 349 lies between – not a square.

Trick: Remember squares ${11}^2$–${20}^2$; 349 is not on the list (between 324 and 361).

Answer: (B) 349

Concept: Fix the definite positions first, then place the conditional ones.

1. A = 4, S immediately above → S = 5.
2. P has two persons between it and A → P = 1 or 7; P is below M (below S), so P = 1.
3. M is between P and S with R just below M: M = 3, R = 2 (M = 2 would push R to 1, occupied).
4. Floor 2 → R.

Trick: Always start from the given floor number (A = 4) and lock positions outward.

Answer: (A) R

Concept: Decode each symbol one link at a time.

1. P # Q → Q is P's sister (Q is female).
2. Q $ R → R is Q's husband.
3. R & S → S is R's (and Q's) son; S & T → T is S's son.
4. T is the son of Q's son → grandson.

Trick: Two '&' (son) links after the couple = two generations down, male → grandson.

Answer: (A) Grandson

Concept: A conclusion follows only if it is true in every possible diagram.

1. Apples ⊂ Fruits, and Fruits ∩ Green = none → Apples ∩ Green = none. II follows.
2. Green ⊂ Vegetables says nothing about apples vs vegetables; apples may or may not be vegetables. I does not follow.

Trick: 'No' + 'All' chains work only through the shared term; vegetables are linked to apples by no such chain.

Answer: (B) Only II follows

Concept: Every letter of the answer must be present in REMARKABLE (count included).

1. Available: two R, two E, two A, plus M, K, B, L.
2. MAKER → M, A, K, E, R – all present ✓.
3. Back needs C, Mineral needs I and N, Market needs T – missing.

Trick: Hunt for one missing letter in each option: C, I, T are absent – eliminates three at once.

Answer: (B) Maker

Concept: Each pair is two consecutive letters, and the pair shifts by +1.

1. BC → CD → DE → EF: first letter B, C, D, E.
2. Next first letter = F, second = G.
3. Next pair = FG.

Trick: Last letter of one pair = first letter of the next: EF → F_ → FG.

Answer: (B) FG

Concept: Compare word and code to find the shift.

1. S→R, U→T, G→F, A→Z, R→Q: every letter moves 1 back.
2. WATER: W→V, A→Z, T→S, E→D, R→Q.
3. Code = VZSDQ.

Trick: A → Z under −1 is the tell-tale; only option (A) has Z in 2nd place.

Answer: (A) VZSDQ

Concept: Three are economic measures/indicators; one is a law.

1. GDP, inflation and fiscal deficit are macro-economic indicators.
2. Right to Education Act (2009) is a social-sector law giving free education to 6–14-year-olds.

Yaad rakhein: RTE flows from Article 21A of the Constitution, added by the 86th Amendment (2002).

Answer: (D) Right to Education Act
