Answer 1

The correct option is D (d) 60/11min. past 7

Ans:13)(d)
When the hands of the clock are in the same straight line but not together, they are 30 minute spaces apart.
At 7 o'clock, they are 25 min. spaces apart.
Minute hand will have to gain only 5 min. spaces.
55 min. spaces are gained in 60 min.
5 min. space are gained in ((60/55)*5)min.= 60/11 min.
Required time= 60/11 min. past 7
