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° | . |
| 2 | 2 | 2 |

@ Sharath and all members
Don't miss guide , if you've not knowledge about anything.
An angle greater than 180 degrees (but less than 360).

Here we consider 10.25 hrs not in min
10.25 min then 10 hrs + (25 min/60)
= 10 + (5/12)
= (120+5)/12
= 125/12.
10.25 min then 10 hrs + (25 min/60)
= 10 + (5/12)
= (120+5)/12
= 125/12.
