C) (10 + 20/143 ) min | D) (10 + 30/143) min |

Answer & Explanation
Answer: A) (10 + 10/143 )min

Explanation:

Explanation:

In a correct clock, the minute hand gains 55 min. spaces over the hour hand in 60 minutes.

To be together again, the minute hand must gain 60 minutes over the hour hand.

55 minutes are gained in 60 min.

60 min. are gained in [(60/55) * 60] min = min.

But they are together after 65 min.

Therefore, gain in 65 minutes = = min.

Gain in 24 hours = = 1440/143 min.

Therefore, the clock gains (10 + 10/143 )minutes in 24 hours.
