Correct Answer:

B) 52 km/hr,26 km/hr

Let the speed of first train be S1 km/hr and speed of second train is S2 km/ hr

As we know ,

Time=total distance(relative speed in same /opp. direction)

In the same direction.

27 sec=(100+95)(s1−s2)×518

27 sec=195×18(s1−s2)×5

s1−s2=26..........1

In the opp. direction,

9 =(100+95)(s1+s2)×518

9=195×18(s1+s2)×5

s1+s2=39×2

s1+s2=78................2

From equation (1) and (2)

s1−s2=26

s1+s2=78

s1=26+782

s1=1042

s1=52 km/hr and s2=26 km/hr
