Q.
A. 20
B. 21
C. 22
D. 24
E. None of the above
Correct choice: C
Explanation:
The hands of a clock coincide 11 times in every 12 hours (Since between 11 and 1, they coincide only once, i.e., at 12 o'clock).
AM
12:00 1:05 2:11 3:16 4:22 5:27 6:33 7:38 8:44 9:49 10:55
PM
The hands overlap about every 65 minutes, not every 60 minutes.
∴ The hands coincide 22 times in a day.
