Question

after 12 o'clock how much time will it take for the hand of clock to meet again​

Answer 1

After 12 o'clock it will take 65 minutes for the hand of the clock to meet again.

• The minute's hand moves one unit per minute.
• The hour's hand moves one unit per ten minutes.
• So when both the hands are at 12 o'clock they'll overlap, but after that when hour hand moves to 1 o'clock, minutes hand has to move 65 units i.e. 65 minutes to meet the hour's hand again at 1 o'clock.
• Therefore, it takes 65 minutes for both hands to overlap again after 12 o'clock.
