- Option B 350m
Let length of the platform be l
300+l/39=300/18
solving this we get l=350m - 12 years agoHelpfull: Yes(1) No(1)
- the length of the train is 257 bt it is not there so ans is data inadequate

- speed=300/18=50/3ms/sec
let length of platform =x
then,
x+300/39=50/3
x=350m - 5 years agoHelpfull: Yes(0) No(0)
