19. Find the angle between the hour hand and the minute hand of a clock when the time is 3.25.
A.47 B.47 1/2
C.49 D.50
Answer:
Angle traced by the hour hand in 12 hours = 360°.
Angle traced by it in 3 hrs 25 min. i.e. 41/12 hrs =
[360 / 12 * 41/12] = 102½°
Angle traced by minute hand in 60 min. = 360°.
Angle traced by it in 25 min. = [360 / 60 * 25]° = 150°.
∴ Required angle = [150° - 102½°] = 47½.
