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° | . |

(11/2)*25 = 30*10(+-)θ.
11*25-600/2 = (+-)θ.
162.5.
Reflex angle = 360- 162.5.
192.5 (option D).
11*25-600/2 = (+-)θ.
162.5.
Reflex angle = 360- 162.5.
192.5 (option D).

Use direct formula.
Which is used to find angle between the two hands at a time, h, m is;
30*h - 5.5*m.
So here,
h=10, m=25.
300*10 - 5.5 * 25 = 162.5.
360 - 162.5 = 197.5 (option D).

Answer is 180 degrees.
In one hour, the hour hand rotates 30 degrees.
In 6 hours, the hour hand rotates 180 degrees.
Hence, the answer is D.

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

Simply;
Angle: (30*hours given)-(11/2 * minutes given).
And here it is told to find the reflex angle so subtract 360° from the angle, we will get the answer.

10:25 ,
10*60+25=625 min.
And 625/2 degree.
25*6 = 150 degree.
∠ = 625/2 - 150 = 325/2.
The reflex angle = 360-325/2 = 395/2 = 197.5.
10*60+25=625 min.
And 625/2 degree.
25*6 = 150 degree.
∠ = 625/2 - 150 = 325/2.
The reflex angle = 360-325/2 = 395/2 = 197.5.
