Q. In a span of 24 hours, how many times would the two hands of a clock point exactly in opposite directions ? - Published on 15 Apr 16a. 10
b. 11
c. 23
d. 22
e. 24
ANSWER: 22
In every hour, the two hands (minute and hour) of the clock would be exactly opposite to each other once. But, from 5 o'clock to 6 o'clock and from 6 o'clock to 7 o'clock (a span of hours), they would be exactly opposite only once (at exact 6 o'clock).
Thus, during the span of 12 hours, the two hands would be exactly opposite 11 times. Hence, in the span of 24 hours they would be exactly opposite 22 times.
