360 | x | 21 |  |
° | = | 157 | 1 | ° |
| 4 | 12 | 4 | 2 |
| Angle traced by min. hand in 15 min. = | |
360 | x 15 | |
° | = 90°. |
| 60 |
 Required angle = |

5 * 30° ~150°.
15 * 5.5~82.5°.
The difference between 150 and 82.5 = 67.5(67 1/2).
15 * 5.5~82.5°.
The difference between 150 and 82.5 = 67.5(67 1/2).

Time 5:15.
30 * 2 = 60.
15/2 = 7.5.
Ans =67 (1/2).
30 * 2 = 60.
15/2 = 7.5.
Ans =67 (1/2).

Angle between them 1 hour is 30 degree so 30+30+30/4=67.5.

How came 21/4?

21/4=5.25
0.25 is 1/4 part of 60min. i.e. 15min
0.25 is 1/4 part of 60min. i.e. 15min

(11/2)*15-30*5=67.5

I think (30*Hrs)-(11/2)*Mins is the correct formula for getting this answer.

@ rekha
5 hrs and 15 min so
5+15/60=5+1/4
20+1/4=21/4
5 hrs and 15 min so
5+15/60=5+1/4
20+1/4=21/4

Please explain how we are getting 21/4
If 15 min is 4th part of 60 min.
then how 21 comes.
If 15 min is 4th part of 60 min.
then how 21 comes.
