Relative speed=s=(120+80)=200km/hr=[200*5/18]m/sec=500/9m/sec
Length of 1st train=d1=270m
Let the length of other train=x metres=d2
Total distance=d1+d2=d
s=d/t
t=9sec
Then
(270+x)/9=500/9
x=230m
Ans is 230 metre

Relative speed = (120 + 80) km/hr =>200km/hr
=(200)x5/18
=500/9 m/sec
Let the length of the other train be x metres.
Then, (x + 270)/9=500/9
x+270=500
x=230 meter
so length of other train =230 meter
