These are the different type of questions asked from this topic.
Type 1: Find the time when the angle between the two hands are given.
Type 2: Find the angle between the 2 hands when the time is given.
Type 3: Find the time, when clocks gaining/losing time.
Type 4: Find the time in the mirror image.
Formula : H x 30 degree - M x 5.5 degree.
H - Hour
M - Minute
Eg: The angle between the minute hand and the hour hand of a clock when the time is 4:20 is:
= 4 x 30 - 20 x 5.5
= 120 - 110
=10 degrees.
Formula : if time is more than 11.00 then subtract it from 23.60 else subtract it from 11.60.
Eg: What will be mirror image of Clock Time 3: 40
= 11:60 - 3:40
= 8:20
