For how many times, the minute hand of a clock will be opposite to the hour hand from 3:00 p.m on Friday to 11:00 a.m on the subsequent Sunday?


A) 40

B) 43

C) 42

D) 45

E) 46

Answer:

Option A

Explanation:

The exception time for the condition e = 180° is 6 O' clock. From, 3:00 p.m. on Friday to 3.00 p.m. on Saturday (i.e., exactly one day), it occurs 22 times. From 3:00 a.m. Sunday to11:00 a.m. Sunday (i.e., exactly 8 hours), the exception time i.e., 6:00 a.m. lies in between. Hence, both the hands will be opposite for (22 + 11 + 7) = 40 times.
