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
