Best answer
Correct Answer - Option 3 : 65

When the minute hand travels 60 minutes, the hour hand only travels 5 minutes.

The relative speed between them (both hands in same direction) = 60 - 5 = 55 minutes

They would meet again after = 60 ÷ 55 = 1.09 hours

1.09 hours = 1.09 × 60 = 65.4 minutes

Hence, they would meet again after 65 minutes.
