Question

"Every hour, a clock chimes as many times as the hour (12:00 = 12 times; 4:00 = 4 times; etc). How many times does it chime from 1 AM through midnight?

Answer 1

Clock strikes once at 1 twice at 2, thrice at 3 and so on. But it only strikes 12 times at most. And then it repeats. So,

No. Of times clock strikes = 2 x (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12)

= 2 x 78

No. Of times clock strikes = 156 times

Therefore, the answer is 156 times.
