The angle between the minute hand and the hour hand of a clock when the time is 4.20, is:
Answer: Option
Explanation:
| Angle traced by hour hand in | 13 | hrs = |  |
360 | x | 13 |  |
° | = 130°. |
| 3 | 12 | 3 |
| Angle traced by min. hand in 20 min. = | |
360 | x 20 | |
° | = 120°. |
| 60 |
Required angle = (130 - 120)° = 10°.

12 hour covers 360 degrees.
Then 360/12 = 30 degrees.
That is one hour.
Then 360/12 = 30 degrees.
That is one hour.

Can we do like this;
(20/60)*30 = 10?
(20/60)*30 = 10?

By common sense it is clear that in 20 minutes the minute hand will move 20*6=120degree and the hour hand will move20*(1/2)=10degree.
Clearly min hand will be at 20 and hour hand will be 10degree apart.
Clearly min hand will be at 20 and hour hand will be 10degree apart.

I think the formula you given (11M-60H)/2 is wrong, It is not coming can you explain it? For example the angle between the two hands at 6:00 it is giving wrong answer.

@Greeshma.
Angle between 2 hands at 6:00.
MIN (M) = 0.
HOUR (H) = 6.
Formula is (|11M-60H|) /2.
So, {|11(0)-60(6)|}/2 = 180.
That's it :-).

Its simple. Just remember for hour hand it covers 0.5 degree in one minute. And minute hand covers 6 degrees.

What do we do if we have a reverse question?
At what time between 3 and 4 clock will there be 36 degree?
