A) (5 + 5/11 )min past 7 B) (6 + 5/11) min past 7
C) 7 D) 8

Answer:   A) (5 + 5/11 )min past 7



Explanation:

When the hands of the clock are in the same straight line but not together, they are 30 minute spaces apart.

Minute hand will have to gain only 5 min. spaces.
55 min. spaces are gained in 60 min.

 

5 min spaces are gained in 6055*5 min  = 5511min 

 

so, Required time = 5511 min  past 7
