Angle between the minute hand of a clock and hour hand when the time is 7 : 20 am is :
(A) 80° (B) 100° (C) 120° (D) 90
Angle traced by the hour hand in 12 hours =
Angle traced by it in 7 hrs 20 minute i.e.,
Angle traced by minute hand in 60 minute =
Angle traced by it in 20 minute =
So, required angle =
Hence, option (B) is correct.
