52. Find at what time between 8 and 9 o'clock will the hands of a clock be in the same straight line but not together.
A. 10x11/10 B. 10x10/11
C. 11x10/11 D. 12x10/11
Answer:
At 8 o'clock, the hour is at 8 and the minute hand is at 12,i.e. the two hands are 20 min. Spaces apart.
So, the minute hand gain = (30 - 20)minute
55 minutes will be gained in 60 min.
10 minutes spaces will be gained in (60/55 x10) min. = 10x10/11 min.
The hands will be in the same straight line but not together at 10x10/11 min.past 8.
