Since we have to find the time after which they will meet so we don't have to add the length of the trains. So the solution goes like this
Total speed of trains = 72+54 = 126km/h
As the distance is in meters so to convert it into meters we first have to convert the speed into m/s.
126 km/h * 5/18 = 35 m/s
Now the distance between the trains is 100m
So by Time = Distance/Speed
Time = 100/35 = 20/7
Good Luck!

speed= 72+54= 126km/h 126x5\18= 35 m/s
distance= 100+200= 300m
time= 300\35 =60\7
distance= 100+200= 300m
time= 300\35 =60\7
