The reflex angle between the hands of a clock at 10.25 is:
Answer: Option
Explanation:

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° | . |

Hello friend... time into fraction
10hrs 25 min should be taken as
10+25/60 = 10+5/12 =(120+5)/12 = 125/12
Thats all.
10hrs 25 min should be taken as
10+25/60 = 10+5/12 =(120+5)/12 = 125/12
Thats all.

Hi Ramya and Pallavi,
We can write 10.25 (10 hrs 25 mins) as 125/12 hrs.
Have a nice day.!
