Q1 · Number System
Find the smallest number which when divided by 12, 15, and 20 leaves a remainder of 8 in each case.
- A. 52
- B. 68
- C. 128
- D. 248
Answer and solution
Answer: B
LCM of 12, 15, 20 = 60. The required number = 60 + 8 = 68.
Q2 · Percentage
A shopkeeper marks his goods 40% above the cost price but allows a discount of 20% on the marked price. What is his profit percentage?
- A. 8%
- B. 10%
- C. 12%
- D. 15%
Answer and solution
Answer: C
Let CP = 100. MP = 140. SP after 20% discount = 140 × 0.8 = 112. Profit = 112 - 100 = 12. Profit % = 12%.
Q3 · Decimals and Fractions
Convert 0.625 into a fraction in its simplest form.
- A. 5/8
- B. 3/5
- C. 7/10
- D. 2/3
Answer and solution
Answer: A
0.625 = 625/1000 = 5/8 after dividing both numerator and denominator by 125.
Q4 · Simple and Compound Interest
The simple interest on a sum at 12% per annum for 2.5 years is ₹1,500. What is the principal amount?
- A. ₹4,000
- B. ₹4,500
- C. ₹5,000
- D. ₹5,500
Answer and solution
Answer: C
SI = (P × R × T) ÷ 100. So 1500 = (P × 12 × 2.5) ÷ 100, giving P = ₹5,000.
Q5 · Elementary Statistics
Find the average of 15, 20, 25, 30, and 35.
- A. 23
- B. 25
- C. 27
- D. 30
Answer and solution
Answer: B
Average = (15 + 20 + 25 + 30 + 35) ÷ 5 = 125 ÷ 5 = 25.
Q6 · Time and Distance
A train travels 240 km in 4 hours. What is its speed in km/h?
- A. 50 km/h
- B. 55 km/h
- C. 60 km/h
- D. 65 km/h
Answer and solution
Answer: C
Speed = Distance ÷ Time = 240 ÷ 4 = 60 km/h.
Q7 · Percentage
If the price of petrol increases by 25%, by what percentage should a consumer reduce consumption so that expenditure remains the same?
- A. 20%
- B. 22%
- C. 25%
- D. 30%
Answer and solution
Answer: A
Required reduction = (25/(100+25)) × 100 = (25/125) × 100 = 20%.
Q8 · Decimals and Fractions
Convert 0.625 into a fraction in its simplest form.
- A. 5/8
- B. 3/5
- C. 2/3
- D. 7/10
Answer and solution
Answer: A
0.625 = 625/1000. Dividing both by 125: 625÷125 = 5, 1000÷125 = 8. So 0.625 = 5/8.
Q9 · Time and Distance
A train traveling at 72 km/hr crosses a platform in 26 seconds and a signal post in 18 seconds. What is the length of the platform?
- A. 120 m
- B. 140 m
- C. 160 m
- D. 180 m
Answer and solution
Answer: C
Train speed = 72 km/hr = 20 m/s. Length of train = 20 × 18 = 360 m. Total distance for platform = 20 × 26 = 520 m. Platform length = 520 - 360 = 160 m.
Q10 · Trigonometry
If sin θ = 3/5 and θ is acute, then the value of (tan θ + sec θ) is:
- A. 7/4
- B. 2
- C. 11/4
- D. 3
Answer and solution
Answer: B
If sin θ = 3/5, then cos θ = 4/5 (Pythagorean triplet). tan θ = 3/4, sec θ = 5/4. Therefore (3/4) + (5/4) = 8/4 = 2.
