- Published on 15 Jun 15

a. 135
b. 130
c. 120
d. 125

ANSWER: 130
 
When minute hand is behind the hour hand, the angle between the minute hand and hour hand at M minutes past H hours is given by:

=> 30 * (H-M/5) + M/2

When minute hand is ahead of hour hand, the formula becomes:

=> 30* (M/5-H) – M/2

Applying the second formula as here the minutes hand is ahead of the hour hand.

=> 30* (40/5-3) – 40/2

=> 30* (8-3) – 20

=> 30*5 – 20

=> 150-20

=> 130

Thus the angle formed is 130 degrees.
