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°.

Convert 3hours into min.
60 * 3 = 180.
Then add 40min.
40+180 = 220.
Then 1 hour is equal to 30degre.
30 * 3 = 90.
Then subtract 220 - 90= 130 will be the answer.
60 * 3 = 180.
Then add 40min.
40+180 = 220.
Then 1 hour is equal to 30degre.
30 * 3 = 90.
Then subtract 220 - 90= 130 will be the answer.

This will bring 140.
The hour hand will be between 3 to 4.
The minute hand will be at 8 because of 40 min.
8-7
7-6
6-5
5-4.
Totally 4*30 =120 degree.
And
Then hour hand will be 40/2 20 degrees.
120 + 20.
=> 140°
The hour hand will be between 3 to 4.
The minute hand will be at 8 because of 40 min.
8-7
7-6
6-5
5-4.
Totally 4*30 =120 degree.
And
Then hour hand will be 40/2 20 degrees.
120 + 20.
=> 140°

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

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

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

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.

@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).
