10.
At 3:40, the hour hand and the minute hand of a clock form an angle of:
Answer: Option
Explanation:
Angle traced by hour hand in 12 hrs. = 360°.
| Angle traced by it in | 11 | hrs = |  |
360 | x | 11 |  |
° | = 110°. |
| 3 | 12 | 3 |
Angle traced by minute hand in 60 min. = 360°.
| Angle traced by it in 40 min. = | |
360 | x 40 | |
° | = 240°. |
| 60 |
Required angle (240 - 110)° = 130°.

3 hour is 30*3=90 and minute 40*5.5,
=220 and different is 220-90=130.

The time is 3:40.
Formula 30(3) - 11/2(40).
Ans = 130°.
Formula 30(3) - 11/2(40).
Ans = 130°.

3:20.
Formula is((11/2)*M-30(H)).
Here H=3 and M=20.then substitute in formula.
((11/2)*20-30(3)).
((110-90))=20.
The angle in between an hour and minute is 20 degree.

@Dheeraj.
For angle between 11:20.
30*11-11/2*20=220 degree or (360-220=140degree for obtuse angle).
For angle between 11:20.
30*11-11/2*20=220 degree or (360-220=140degree for obtuse angle).

@Vijay.
3hrs 20 minuts
By simple formula
(30*h-11/2)=angle
30*3-11/2*20= 20
.

The answer is 20°.

Can anyone tell me angle when it is 3:20?

I think the answer should be less than 130 degrees.
Because, here minute hand is at "8" and hour hand is not exactly at "3". The hour hand is slightly shifted past "3". So, slightly reduction in degrees. But not exactly 130 degrees.
Am, I right?
