The reflex angle between the hands of a clock at 10.25 is:

180

195

192 1/2

197 1/2

Explanation:

Angle traced minutes hand in 25 minutes = 25×360/60?=150^°
The hour hand traces half a degree in one minute. Hence, angle traced by hour hand at 10 hour and 25 minutes = 10×30+225?=312.5^°
Thus, angle between two hands = 312.5−150=162.5^°
Hence, the reflex angle is = 360−162.5=197.5^°
