At 3:40, the hour hand and the minute hand of a clock form an angle of  Choose the correct option:
A) 160°
B) 180°
C) 130°
D) 110°
E) 150°
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 degree   When the minute hand is ahead of the hour hand, the angle between the two hands at M minutes past H 'o clock   =30(M/5−H)−M/2 degree   Here H = 3, M = 40 and minute hand is ahead of the hour hand.   Hence the angle   =30(M/5−H)−M/2   =30(40/5−3)−40/2   =30(8−3)−20   =30×5−20 =130°   Answer is 130°.
