The reflex angle between the hands of a clock at 21.25 is:
(A)
200 degrees
(B)
220.7 degrees
(C)
182 degrees
(D)
227.5 degrees
Answer: (D)
Explanation:
Reflex angle: The angle which has a measure between 180 and 360 degrees are called a Reflex Angle. Angle traced by hrs hand in 9 25/60 = 113/12 hrs = (360/12)*(113/12) = 282.5 degrees Angel traced by minutes hand in 25 minutes = (360/60)*25 = 150 degrees
- Reflex angle = 360 – (282.5 – 150) = 227.5 degrees
