Question

A man covered 30% of the distance in one hour and in the next hour, it covered 10% of the remaining distance. If total distance is 900 m, then find the distance covered in second hour.
1. 23 m
2. 63 m
3. 45 m
4. 15 m

Answer 1

Correct Answer - Option 2 : 63 m

Given

Total distance = 900 m

Calculation

Distance covered in 1 hour = 30% of 900

⇒ 270

Remaining distance = 900 - 270

⇒ 630

Distance covered in next hour = 10% of 630

⇒ 63

∴ Distance covered in second hour is 63 m.
