Question

A clock shows the time as 7 am. If the minute hand gains 3 minutes every hour, how many minutes will the clock gain by 11 pm?
1. 52 minutes
2. 48 minutes
3. 16 minutes
4. 28 minutes

Answer 1

Correct Answer - Option 2 : 48 minutes

We know that the clock gains 3 minutes every hour.

Number of hours between 7 am and 11 pm = number of hours between 7 am and 12 noon + number of hours between 12 noon and 11 pm

⇒ 5 + 11

⇒ 16 hours

Therefore, in 16 hours, the clock will gain = 16 × 3 = 48 minutes

Hence, 48 minutes is the correct answer.
