1.  The angle between the minute hand and the hour hand of a clock when the time is 4.15 is:
A. 0
B. 37.5
C. 27
D. 15

Answer: Option B

Explanation:

Angle between hands of a clock

When the minute hand is behind the hour hand, the angle between the two hands at M minutes past H 'o clock

=> 30(H − M/5) + M/2 degrees

Here H = 4, M = 15 and the minute hand is behind the hour hand.

Hence the angle
= 30[4-(15/5)]+15/2 = 30(1)+7.5 = 37.5 degrees
