Question

The minute hand of A clock overtakes The hour hand at interval of 64 minutes of correct time how much a day does the clock gain or loss?
​

Answer 1

Step-by-step explanation:

time difference = 24*60 - 22*65 = 10 minutes. Answer - For a normal clock, time taken by minute hand to overtake the hour hand = 65 + 5/11 minutes. Since for this clock, the minute hand takes only 65 minutes, the clock gains 5/11 minutes every 65 minutes. Therefore, in 24 hours, the clock gains 1440/143 minutes.
