Numerical ability questions
Q1: CI half yearly
Problem: CI on ₹8000 at 10% p.a. for 1 year compounded half-yearly?
Solution: Rate per half-year = 5%. Amount = 8000 × (1.05)² = 8000 × 1.1025 = 8820. CI = 820.
Answer: ₹820
Q2: Distance from speed
Problem: A vehicle travels at 60 km/h for 2.5 hours. How far does it go?
Solution: Distance = speed × time = 60 × 2.5 = 150 km.
Answer: 150 km
Q3: Train and pole
Problem: A train 150 meters long passes a pole in 15 seconds. What is its speed in km/h?
Solution: Distance = 150 m = 0.15 km. Time = 15 s = 15/3600 h = 1/240 h. Speed = 0.15 ÷ (1/240) = 0.15 × 240 = 36 km/h.
Faster check: 150/15 = 10 m/s → 10 × 18/5 = 36 km/h.
Answer: 36 km/h
Q4: Man days leftover
Problem: 15 men can do a job in 20 days. After 5 days, 5 men leave. How many more days to finish?
Solution: Work done in 5 days = 15×5 = 75 man-days. Total = 300. Left = 225. Remaining men = 10. Days = 225/10 = 22.5 days.
