Q:

The reflex angle between the hands of a clock at 11:35 is ?

A) 137.5 degrees B) 222.5 degrees
C) 192.5 degrees D) 330 degrees
 
Answer & Explanation Answer: B) 222.5 degrees

Explanation:

Apply the formula for finding the angle:
Angle=(30h-(11/2)m( where m stands for minutes and h stands for hours)
Hence, 30x11 - 11/2x35 = 330 - 192.5 = 137.5 degrees
The reflex angle = 360 - 192.5 degree = 222.5 degrees.
