A 300 meter long train crosses a platform in 39 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform.

A. 310 meter

B. 335 meter

C. 345 meter

D. 350 meter

Correct Answer : D.


Speed = Distance/time = 300/18 = 50/3 m/sec
Let the length of the platform be x meters
then
Distance= Speed×Timex+300=503×39⇒3(x+300)=1950⇒x=350 meters
