Q&A: practice questions with answers

Concept: The least distance of distinct vision (near point) of a normal eye is about 25 cm.

1. Closer than ~25 cm, the eye lens cannot curve enough, so the image blurs.
2. Far point of a normal eye is infinity.

Trick: 25 m, 2.5 m are far too large and 2.5 cm is touching the eye – only 25 cm is sensible.

Answer: (C) 25 cm

Concept: BNSS Section 187 (old CrPC Sec. 167) caps custody during investigation.

1. Offences punishable with death, life or 10+ years: limit 90 days.
2. Other offences (less than 10 years): limit 60 days.
3. If no charge-sheet by then, the accused gets default bail.

Yaad rakhein: BNSS, BNS and BSA replaced CrPC, IPC and Evidence Act from 1 July 2024.

Answer: (C) 60 days

Concept: SVAMITVA is a Panchayati Raj scheme for village (abadi) land records.

1. Drones survey inhabited village land and property cards are given to owners – A true.
2. It covers only rural inhabited areas, not urban regions – R false.

Yaad rakhein: SVAMITVA = Survey of Villages And Mapping with Improvised Technology in Village Areas; launched 24 April 2020.

Answer: (C) A is correct, but R is incorrect

Concept: Poikkal Kuthirai (“false-leg horse”) is a Tamil folk dance.

1. The dancer fixes a dummy horse body around the waist and dances on wooden stilts.

Yaad rakhein: Similar dummy-horse dances: Kachhi Ghodi (Rajasthan).

Answer: (D) Tamil Nadu

Concept: CPI (Transparency International) scores countries 0–100.

1. 0 = highly corrupt; 100 = very clean.
2. So a score near 0 means more perceived corruption.
3. Options A, B, C all describe a high score.

Trick: Three options say the same “good” thing – the odd one out, “More corruption”, is the answer.

Answer: (D) More corruption

Concept: Agro-based industries get raw material from crops.

1. Cotton textiles use cotton; sugar mills use sugarcane – both farm products.
2. Steel, aluminium, cement and petrochemicals use minerals/petroleum.
3. Each wrong pair has one mineral industry.

Trick: Pick the pair with no metal or mineral in it.

Answer: (C) Cotton Textiles and Sugar

Concept: The Great Indian Bustard survives mainly in Rajasthan's Thar desert.

1. Desert National Park, Jaisalmer is its main home and breeding programme site.
2. Captive-bred birds were reported released/breeding there in 2025.
3. Gir – lions; Kaziranga – rhinos; Ranthambhore – tigers.

Yaad rakhein: GIB is Rajasthan's state bird and is Critically Endangered (IUCN).

Concept: One Fundamental Right was moved out of Part III by the 44th Amendment (1978).

1. Right to Property (Art. 19(1)(f) and Art. 31) was deleted from Fundamental Rights.
2. It now sits in Art. 300A (Part XII): no one can lose property except by authority of law.

Yaad rakhein: 44th Amendment was passed by the Janata Government under Morarji Desai.

Answer: (B) Right to Property

Concept: Aditya-L1 carries remote-sensing and in-situ instruments; solar wind is measured in-situ.

1. ASPEX = Aditya Solar wind Particle EXperiment – studies solar wind particles at L1.
2. SUIT – ultraviolet imaging of the Sun; SoLEXS and HEL1OS – solar X-rays.

Trick: Read the acronym: ASPEX has “Solar wind Particle” in its full form.

Answer: (C) ASPEX

Concept: India is a federation with a strong Centre (“quasi-federal”).

1. Union List, residuary powers, emergency provisions, all-India services – Centre is stronger; statement 1 true.
2. The word “federal” is not used anywhere; Art. 1 calls India a “Union of States” – statement 2 false.

Yaad rakhein: K.C. Wheare described India as “quasi-federal”.

Answer: (A) Only 1

Concept: Convert mixed fractions to decimals, then apply BODMAS.

1. $1\frac{1}{5}=1.2\to 3.2-1.2=2$.
2. $2\frac{1}{4}=2.25$; ÷ 0.5 is the same as × 2 → 4.5.
3. 2 + 4.5 = 6.5.

Trick: Dividing by 0.5 = doubling. Saves a long division step.

Answer: (B) 6.5

Concept: Find Marketing's share, subtract expenses, then split the balance.

1. Marketing = $\frac{4}{12}\times 48,000=$ ₹16,000.
2. Spent: $3,000+1,500=$ ₹4,500 → left ₹11,500.
3. Smaller share (2 of 5 parts) = $11,500\times \frac{2}{5}=$ ₹4,600.

Trick: Balance must split into 5 parts exactly: $11,500÷5=2,300$ → 2 parts = 4,600.

Answer: (C) ₹4,600

Concept: Solve from the bottom (innermost) level upward. Here $x=1+\frac{1}{3+\frac{1}{1+\frac{1}{2}}}$.

1. $1+\frac{1}{2}=\frac{3}{2}$ → its reciprocal $=\frac{2}{3}$.
2. $3+\frac{2}{3}=\frac{11}{3}$ → reciprocal $=\frac{3}{11}$.
3. $x=1+\frac{3}{11}=$ $\frac{14}{11}$.

Trick: x is just above 1 (1 + something small) – $\frac{14}{11}\approx 1.27$ is the only option that fits.

Answer: (A) $\frac{14}{11}$

Concept: Profit share ∝ capital × months.

1. Amit (in ₹ thousand): 90 for 6 months and 60 for 6 months → $540+360=900$.
2. Sumit: 60 for the last 9 months → 540.
3. Ratio = 900 : 540 = 5 : 3.

Trick: Work in thousands: Amit $90\times 6+60\times 6=900$; Sumit $60\times 9=540$ → divide by 180.

Answer: (C) 5 : 3

Concept: Share ratio = capital × time.

1. Ram: $60\times 10=600$; Shyam: $90\times 8=720$ (in thousands).
2. Ratio 600 : 720 = 5 : 6 (total 11).
3. Ram = $\frac{5}{11}\times 40,000=$ ₹18,181.82.

Trick: Ram's ratio is smaller, so his share is below ₹20,000 – only ₹18,181.82 qualifies.

Answer: (D) ₹18,181.82

Concept: Numbers in the two groups are in the inverse ratio of their distances from the overall average.

1. Officers: $56,000-32,000=24,000$ away.
2. Non-officers: $32,000-20,000=12,000$ away.
3. Officers : Non-officers = 12 : 24 = 1 : 2 → non-officers = $2\times 17=$ 34.

Trick: Answer must be a multiple of 17 – only 34 is.

Answer: (A) 34

Concept: Add all three conditions; every number appears with the same total coefficient.

1. Each number appears twice fully + once as half → coefficient 2.5.
2. $2.5\times (a+b+c)=225+213+192=630$.
3. Sum = 252 → average = $252÷3=$ 84.

Trick: Average = total ÷ (2.5 × 3) = $630÷7.5=84$ in one step.

Answer: (A) 84

Concept: Compare required correct answers with actual correct answers.

1. Needed: 80% of 120 = 96.
2. Got: 70% of 20 + 60% of 50 + 60% of 50 = 14 + 30 + 30 = 74.
3. More needed = 96 − 74 = 22.

Trick: Hindi + Science = 100 questions at 60% → 60 directly; add 14 for Math.

Answer: (D) 22

Concept: Compound for full years; for the leftover months apply simple interest on the new amount.

1. Year 1 at 9%; the next 8 months = $\frac{2}{3}$ year → $9\times \frac{2}{3}=6\%$.
2. Amount = $8,000\times 1.09\times 1.06=8,720\times 1.06=$ ₹9,243.2.
3. CI = amount − principal = ₹1,243.20.

Trick: Effective % = $9+6+\frac{9\times 6}{100}=15.54\%$ → 15.54% of 8,000 = 1,243.20.

Answer: (B) ₹1243.20

Concept: The amount of one year becomes the principal of the next year.

1. Interest in 3rd year = $12,100-11,000=$ ₹1,100.
2. This is earned on ₹11,000.
3. Rate = $\frac{1,100}{11,000}\times 100=$ 10%.

Trick: Ratio 12,100 : 11,000 = 11 : 10 → growth of $\frac{1}{10}=10\%$.

Answer: (C) 10%
