Q&A: practice questions with answers

Concept: A letter common to two words takes the digit common to both codes.

1. GIVE → 6482 and VOLT → 3671
2. Common letter: V; common digit: 6
3. So V = 6.

Trick: Match common letters with common digits – order inside the code does not matter.

Answer: (B) $6$

Concept: Find the differences between consecutive terms.

1. $892-2=890$, $890-4=886$, $886-6=880$, $880-8=872$
2. Differences grow by 2: next is $-10$
3. $872-10=862$

Trick: Subtracting consecutive even numbers – the next difference is 10.

Answer: (A) $862$

Concept: Write letter positions and compare the two clusters of each pair.

1. LQ–SP: $L(12)\stackrel{+5}{\to }Q(17)$; $L\stackrel{+7}{\to }S$, $Q\stackrel{-1}{\to }P$
2. UZ–BY: $U\stackrel{+5}{\to }Z$; $U\stackrel{+7}{\to }B$, $Z\stackrel{-1}{\to }Y$; EJ–LI: $E\stackrel{+5}{\to }J$; $E\stackrel{+7}{\to }L$, $J\stackrel{-1}{\to }I$
3. JO–QM: $J\stackrel{+5}{\to }O$, $J\stackrel{+7}{\to }Q$, but $O\stackrel{-2}{\to }M$ ✗

Trick: Check the last letters: second letter $-1$ in three pairs; only JO–QM breaks it.

Answer: (A) JO – QM

Concept: Place the fixed clues first, then fill the rest.

1. A odd, not 3 → 1 or 5; $C+A=4$ → A = 1, C = 3
2. $D+E=10$ → (4, 6) or (6, 4); B just above D → D = 4, B = 5, so E = 6
3. F gets the only free floor, 2; check: between E(6) and F(2) are 3 people ✓
4. Below F: only A → 1 person

Trick: Sum clues with small totals (A + C = 4) fix positions fastest.

Answer: (B) $1$

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

1. smooth long drive → zi ma tu
2. challenging mountain drive → fo se zi
3. Common word "drive" ↔ common code "zi".

Trick: Common word ↔ common code; position in the sentence is irrelevant.

Answer: (C) zi

Concept: For people facing the centre, left = clockwise and right = anticlockwise.

1. Fix I; counting to I's left, H is the 4th seat (3 between).
2. Number seats clockwise from I (I = 0, H = 4). B sits between G and H. If B = 3, G = 2, then A = 5 and C = 4 = H ✗. So B = 5 and G = 6.
3. A is 4th to G's right (seat 2), C is just right of A (seat 1), and D takes the last seat: clockwise I, C, A, D, H, B, G.
4. Two seats to D's left (clockwise): H, then B.

Trick: Draw the circle and mark arrows for "left" before placing anyone.

Answer: (B) B

Concept: Find the operations from the given sets.

1. $6\stackrel{\times 2}{\to }12\stackrel{+3}{\to }15\stackrel{\times 2}{\to }30$; $4\stackrel{\times 2}{\to }8\stackrel{+3}{\to }11\stackrel{\times 2}{\to }22$
2. (C): $11\stackrel{\times 2}{\to }22\stackrel{+3}{\to }25\stackrel{\times 2}{\to }50$ ✓
3. (D) fails: $19\times 2=38\ne 36$; (A), (B) fail at the first step.

Trick: Pattern $\times 2,+3,\times 2$ → the last term must be even and twice the third.

Answer: (C) 11 - 22 - 25 - 50

Concept: Number the positions 1 (bottom) to 7 (top) and place the definite boxes first.

1. Two below C → C = 3; one above A → A = 6
2. One box between A and E → E = 4
3. B just above F: the only adjacent free pair is 1–2 → F = 1, B = 2
4. D below G → D = 5, G = 7. Order (bottom→top): F, B, C, E, D, A, G
5. Boxes above B = 7 − 2 = 5

Trick: Boxes above position p = 7 − p.

Answer: (B) $5$

Concept: In PowerPoint, the Enter key inside a text box starts a new paragraph (new line).

1. While typing in a text box/placeholder, pressing Enter moves the cursor to the next line in the same text box.
2. A new slide is inserted with Ctrl+M or Enter only in the slide-thumbnail pane, not inside a text box.
3. Enter neither deletes text nor is meant to resize the box.

Yaad rakhein: Enter = new paragraph; Shift+Enter = line break in the same paragraph; Ctrl+M = new slide.

Answer: (C) The cursor moves to the next line within the same text box.

Concept: India's population growth (1901–2011) is studied in four phases.

1. Phase I (1901–1921): stagnant growth.
2. Phase II (1921–1951): steady growth – 1921 is called the 'demographic divide'; death rate fell due to better health and sanitation.
3. Phase III (1951–1981): population explosion; Phase IV (1981 onwards): high but slowing growth.

Yaad rakhein: Stagnant → Steady → Explosion → Slowing (S-S-E-S).

Answer: (B) Phase II: 1921-1951

Concept: After the Kalinga war, Ashoka adopted Buddhism and spread Dhamma.

1. After the Third Buddhist Council (Pataliputra, under Moggaliputta Tissa), Ashoka sent missionaries abroad.
2. His son Mahendra and daughter Sanghamitra were sent to Sri Lanka; missions also went to Suvarnabhumi and West Asia.
3. Chandragupta II was a Gupta ruler, not Mauryan.

Yaad rakhein: Ashoka – Third Council – Mahendra & Sanghamitra to Sri Lanka.

Answer: (B) Ashoka

Concept: Bile salts emulsify fats; without bile, fats and the fat-soluble vitamins (A, D, E, K) are poorly absorbed.

1. A blocked bile duct (obstructive jaundice) stops bile from reaching the intestine.
2. Fat malabsorption follows, leading to deficiency of fat-soluble vitamins – among the options, Vitamin A.
3. Vitamin B12, B1 and C are water-soluble; B12 needs intrinsic factor and the ileum, not bile.

Yaad rakhein: Bile problem → "ADEK" deficiency (night blindness, rickets, bleeding).

Answer: (A) Vitamin A

Concept: The subtropical westerly jet stream controls the onset and retreat of the Indian monsoon.

1. In summer the jet shifts north of the Himalayas, allowing the monsoon to set in.
2. By September–October it returns south of the Himalayas; its descending air causes subsidence (sinking, dry air) and high pressure over the land.
3. Subsidence suppresses convection and rainfall, so the monsoon withdraws.

Yaad rakhein: Jet north → monsoon arrives; jet back south → sinking air → monsoon retreats.

Answer: (B) Inducing subsidence over land

Concept: In eastern India, paddy (rice) is grown in three seasons a year.

1. Aus – autumn rice (sown pre-monsoon, harvested Aug–Sep).
2. Aman – winter rice, the main kharif crop (harvested Nov–Dec).
3. Boro – summer/rabi rice grown with irrigation.

Yaad rakhein: Aus–Aman–Boro = three rice crops of Assam, West Bengal, Odisha.

Answer: (C) Paddy

Concept: NHRC is a statutory body under the Protection of Human Rights Act, 1993.

1. The Chairperson and members are appointed by the President.
2. The President acts on the recommendation of a six-member committee headed by the Prime Minister (includes Lok Sabha Speaker, Home Minister, LoP of both Houses, Rajya Sabha Deputy Chairman).
3. The Chairperson is a former Chief Justice of India or a former SC judge.

Yaad rakhein: PM's committee recommends, President appoints.

Answer: (B) The President of India

Concept: Vikram 3201 is India's first fully indigenous 32-bit microprocessor for space use.

1. Developed by ISRO's VSSC and fabricated at the Semi-Conductor Laboratory (SCL), Mohali.
2. It is made with 180 nm CMOS technology and presented in 2025 (Semicon India).
3. It succeeds the 16-bit Vikram 1601 used in ISRO launch vehicles.

Yaad rakhein: Vikram 3201 – 32-bit – SCL Mohali – 180 nm.

Answer: (C) 180nm CMOS technology

Concept: Dandiya Raas is the Navratri dance of Gujarat.

1. It is performed with pairs of decorated sticks (dandiyas).
2. The sticks represent the swords of Goddess Durga, and the dance depicts a mock fight between Durga and Mahishasura.
3. Kalbelia and Ghoomar are Rajasthani dances; Tarangmel is from Goa.

Yaad rakhein: Dandiya sticks = Durga's swords.

Answer: (B) Dandiya Raas

Concept: Archery World Cup Stage 1, 2025 was held at Auburndale, Florida (USA) in April 2025.

1. India's men's recurve team – Dhiraj Bommadevara, Atanu Das and Tarundeep Rai – won silver after losing the final to China.
2. Abhishek Verma is a compound archer, so options with him are wrong.

Yaad rakhein: Recurve men 2025 = Dhiraj–Atanu–Tarundeep (silver, Florida).

Answer: (D) Dhiraj Bommadevara, Atanu Das and Tarundeep Rai

Concept: Capital acquisitions of the armed forces are governed by the Defence Acquisition Procedure (DAP) 2020.

1. In 2024 the Ministry of Defence added fast-track procurement provisions to the DAP to cut acquisition timelines.
2. The Defence Procurement Manual covers revenue (routine) purchases, not capital acquisition.
3. The offset policy relates to investment obligations of foreign vendors, not speed of procurement.

Yaad rakhein: Capital buys → DAP; revenue buys → DPM.

Answer: (A) Defence Acquisition Procedure

Concept: In Odisha, the 1857 revolt was led at Sambalpur by Veer Surendra Sai.

1. Surendra Sai, a claimant to the Sambalpur throne, fought the British from 1857 to 1862 and was later exiled to Asirgarh fort.
