Q:

Find the angle between the hour hand and the minute hand of a clock when the time is 3.25

A) 47.5 degrees B) 57.5 degrees
C) 45.5 degrees D) 55.5 degrees

Answer:   A) 47.5 degrees



Explanation:

At 3 O'clock, Minute hand is at 12 while the Hour hand is at 3. Again the minute hand has to sweep through ( 30 x 5 ) ie 150° for reaching the figure 5 to show 25 mins. 

Simultaneously the Hour hand will also rotate for 25 mins. Thus starting from the mark, 3 the hour hand will cover an angle = (25 x 30) / 60 = 12.5° 

Hence, Angle between Hour and the Minute hand = ( 60 - 12.5 ) = 47.5°
