Q:

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 & Explanation Answer: B) 37.5

Explanation:

Angle between hands of a clock

=> $30 (H - \frac{M}{5}) + \frac{M}{2}$ 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
