Find angle between the hour hand the minute hand of a clock when time is 3:40 that is 40 minutes past 3

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

• c. 130 degree
  
  For 60 minutes hour hand will move 30 deg., so for 40 minutes it will move 20 deg.
  So total angle between hour hand & minute hand=(Angle betn. hour hand & 20 min. position) + (Angle betn. 20 min. position & 40 min. position)=10+120 =130 degree
