HERE IS YOUR ANSWER
the relative speed of trains is 72 - 27 = 45kmph = 12.5 m/s
the distance the super fast train covers = 100 + the length of the passenger train (x)
time taken to cross = 20 sec
distance = speed × time
100 + x = 12.5 × 20
100 + x = 250
x = 150 m
therefore the length of the passenger train is 150 metres
