A clock is started at noon. By 10 minutes past 5, the hour hand has turned through how many degrees:
320 degree
135 degree
155 degree
none of these
165 degree
Hour hand covers 30 degrees in 1 hour.
5 hours & 10 Min => 5(1/6) or 31/6 hours
Thus, the angle covered in 31/6 hours = 30 x 31/6 => 155 degree
