The reflex angle between the hands of a clock at 10.25 is:
Answer: Option
Explanation:
| Angle traced by hour hand in | 125 | hrs = |  |
360 | x | 125 |  |
° | = 312 | 1 | ° | . |
| 12 | 12 | 12 | 2 |
| Angle traced by minute hand in 25 min = | |
360 | x 25 | |
° | = 150°. |
| 60 |
 Reflex angle = 360° - |
|
312 | 1 | - 150 | |
° | = 360° - 162 | 1 | ° | = 197 | 1° | . |

Please let me know why "Angle traced by hour hand" is calculated for 125 /12 hrs

This is simple way to find angle between the hands in a clock.
|30h- (11/2) m| where "h"indiacates hours and m indicates minutes.

Yes. You can solve like that. But why not go for more faster step. 10+25/60. It will ease your calculation.

Hi haimanti i think so ur guess is correct bcoz,10 is hour so to make it minute *60
ie)10*60=600+25
=625/60
=125/12
ie)10*60=600+25
=625/60
=125/12

Why we have to find out 150 degree?

The formula to calculate the angle between the 2 hands is
(30 H - 11/2M)
Where H - the hour reading
M - the min reading
(30 H - 11/2M)
Where H - the hour reading
M - the min reading

(10*60 + 25)/60??
(10*60 + 25)/60??
