Q.  At what time between 4 and 4.59 will the hands of a watch point in opposite directions?
- Published on 15 May 17

a. 45 min. past 4
b. 40 min. past 4
c. 50 (4/11) min. past 4
d. 54 (6/11) past 4

ANSWER: 54 (6/11) past 4
 
At 4 o'clock, the hands of the watch are 20 min. spaces apart.

To be in opposite directions, they must be 30 min. spaces apart.

Minute hand must gain 50 min. spaces.

55 min. spaces are gained in 60 min.

50 min. spaces are gained in 60/55 x 50 = 54 (6/11) min

Required time = 54 6/11 min past 4
