- Published on 13 Apr 17

a. 32°
b. 37°
c. 32.5°
d. 37.5°

ANSWER: 37.5°
 
At 4 o’ clock, the hour hand is at 120° from the vertical.

In 15 minutes,

Hour hand = 120 + 15 x (0.5) = 120 + 7.5 = 127.5° (The hour hand moves at 0.5 dpm)

Minute hand = 15 x (6) = 90° (The minute hand moves at 6 dpm)

Difference or Angle between the hands = 127.5 – 90 = 37.5°
