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° | . |

I know what is reflex angle but please tell me how they calculated it? why have they subtracted 150 from 312 and half degree and the obtained no. from 360 degree. Please explain.

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.

@ 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).

Can you please clear if this is correct calculatioon for 10 hr 25 min i.e.:
(10*60 + 25)/60??
(10*60 + 25)/60??

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

Why we have to find out 150 degree?

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
