At what angle the hands of a clock are inclined at 15 minutes past 5?
Answer: Option
Explanation:
| Angle traced by hour hand in | 21 | hrs = |  |
360 | x | 21 |  |
° | = | 157 | 1 | ° |
| 4 | 12 | 4 | 2 |
| Angle traced by min. hand in 15 min. = | |
360 | x 15 | |
° | = 90°. |
| 60 |
 Required angle = |
|
157 | 1 | |
° | - 90° = 67 | 1 | ° |
| 2 | 2 |

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.

5:15, means hour hand is on 5 and minute hand is on 3.
Now, 360/12=30.
Angle between any two numbers on the clock is 30 degrees.
Now angle between 3 and 6 is 90 degree.
Angle between 6 and 5 is 30 degree.
Thus 90-30=60;.
Angle between 5 and 3 is approximately 60 degrees.
