= 4.20 ( Here 1 hour = 60 mins, 1/3 of 60 is equal to 20).
Hope you understand guys. Have a nice day!

angle=(11/2)*min-30*hrs
apply this formula you can get the answer ......

we can convert it in hours as:
20min.=1/3hours
so total hours as 4+1/3=13/3

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.

Apply the formula suggested by Reddilavan..
ie: Angle = 30Hr-(11/2)Min

In first can we take 12/3 instead of 13/3 ?

Hi girls ! we can write 4.20 also as 13/3, we covert 20 min into hrs 20/60=1/3 and we add with4 hrs 4+1/3=13/3.
Have a nice day.

Direct formula:
|11M-60H|/2
where M=minute, H=hour hands.

Why we are substracting angle traced by hour hand and angle traced by minute hand ?
One another thing is that - if we see the clock at 4.20 hour hand is at 4 and minute hand is also at 4. So angle between them must be 0 degree.
Please clear me.

I agree with Saum. Can someone please clear our doubt?

@Saum
We take 12 O'clock point as reference point (r.p).
So we subtract the angle move by hr hand from the r.p. and the angle move by the min hand from the same to get the separating angle between them
and also at 4:20 the hands doesn't coincide in my watch.

We can also mark the ans by common sense..ie,
1. It is clear that the angle could not be 0.
2. Since the hour hand leads the min hand, and it will be in between 4 to 5, if the time will be 4.30, hour hand exactly in mid of 4 n 5, i.e 5min=30 degree, than half is 15 degree if the time would 4.30, but it is less than the 4.30, so angle will be slightly less than the 15 degree.

Here is a simple formula to get an angel between hands..
30*[ Difference b/t hours and ( min /5) ]+ (min/2)
Take an example 4:20
30*[4~20/5]+(20/2)=0+10 = 10

60 parts by min hand = 5 parts by hr hand.
20 parts by min hand = (5/60) *20 = 1 2/3 part by hr hand.
1 part = 6 degree.
1 2/3 part = 10 degree.

To find angle take this formula.
Angle= ( (11/2) *min-30*hour).
If we get angle value as negative take that value as positive. That will be the answer.

Hey all.
We know that the minute hand is at 4 at 4. 20. We jst hav to calculate the angle moved by hour hand from 4 for 20 min.
For 60 min, Hour hand covers 360/12=30 degree.
For 20min, it covers 30*20/60= 10 degree. (Just cross multiply. ).
Required angle = (130 - 120)º = 10º.
