How many times in a day will the hour hand and the minute hand of a clock coincide?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 22 times
In 12 hours the minute hand goes round 12 times and the hour hand once, so the minute hand gains 11 full rounds on the hour hand. It catches up with the hour hand once for every round it gains.
In 12 hours: 11 times, not 12, because between 11 and 1 o'clock the hands meet only once, at 12
In a day of 24 hours: \(2\times11=22\) times
