A. 47*1/2°

B. 48*1/2°

C. 49*1/2°

D. 50*1/2°

Correct Answer :

A. 47*1/2°


angle traced by the hour hand in 12 hours = 360°


Angle traced by it in three hours 25 min = 41/12 hrs=(360*41/12*12)° =102*1/2°


angle traced by minute hand in 60 min. = 360°.


Angle traced by it in 25 min. = (360 X 25 )/60= 150°


Required angle = 1500 – 102*1/2°= 47*1/2°
