A 300 m long train crosses a platform in 33 sec while it crosses a signal pole in 18 sec. What is the length of the platform?
Choose the most appropriate option.
A) 286 m
B) 250 m
C) 277 m
D) 278 m
E) 267 m
Speed = 300/18 = 50/3 m/sec.   Let the length of the platform be x meters.   Then, (x + 300)/33 = 50/3   =&gt; x = 250 m.   Answer:250 m
