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

10.25=10hrs 15 minutes
bcoz it is in decimal,
we have to convert it into hrs and minutes

What is the angle between the hour hand and minute hand, when the clock shows 10.25?

@Akshay
Please give me the derivation of this formula Angle=|30(hh)-11/2(mm)|.

10 hr 25 min =10 * 60 min + 25 min = 625 min.
625 min = 625/60 hr = 125/12 hr.
625 min = 625/60 hr = 125/12 hr.

Can anyone please explain me the calculation part of (360/12 *125/12)degrees?

But 30*9-11/2*0 = 270 why please explain the angle between hands at 9.00 am.

We can use this formula too,
Reflex angle = 360-theta.
Theta = 1/2(60h-11m).
Reflex angle = 360-theta.
Theta = 1/2(60h-11m).

General formulae is (30h-11/2m).
But for reflection angle 360-(30h-11/2m).
But for reflection angle 360-(30h-11/2m).
