Question

How many times in a day do minutes and hours hands of a dock cross each other?​

Answer 1

Answer:

We know that the minute and hour hand coincide every 65 minutes and not 60 minutes. Also, the hour and minute hand coincide only once between 11 and 1 o'clock i.e. at 12 o'clock. So, from both the above statements we can say that the two hands coincide exactly 11 times in a 12 hour span.

Answer 2

Answer:

The hands of a clock meet once in every hour but between 11:00 and 1:00 'o'clock they coincide only once therefore the hands of a clock meet 11 times in 12 hours hence 22 is the correct answer
