1.  At what time between 3 and 4 o’clock will the minute hand and the hour hand are on the same straight line but facing opposite directions ?
A. 3:15 2/8
B. 3:49
C. 3:49 1/11
D. 3:51

Answer: Option C

Explanation:

On straight line means 180 degree angle.
180 = 11/2 min – 30 hrs
180 = 11/2 m – 30 × 3
180 = 11/2 m – 90
(180 + 90) 2 = 11 m
m = 540/11 = 49 (1/11) minutes.
