You need to use the concept of relative velocity here. The relative velocity in this case will be 54+30 as both the trains are running in opp direction. Also the distance needed to be traveled will be 120+80=200 m = 0.2 Km.
Time = Distance/Speed = 0.2/84 = 0.00238 Hr = 8.5 Seconds
Time = Distance/Speed = 0.2/84 = 0.00238 Hr = 8.5 Seconds
