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°.

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

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).

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

130° is right answer. I agree.

°=11/2 min.-30H.
So,11*40/2-30*3,
°= 220-90,
= 130(answer).
So,11*40/2-30*3,
°= 220-90,
= 130(answer).

11/2*40 = 220.
30*3 = 90.
220-90 = 130.
30*3 = 90.
220-90 = 130.

(11*minute-60*hour)/2
= (11*40-60*3)/2.
= 130.
= (11*40-60*3)/2.
= 130.
