A 300 meter long train crosses a platform in 27 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform?
Choose the most appropriate option:  A) 150m  B) 278m  C) 350m  D) 228m  E) 282m
Speed = [300 / 18] m/sec = 50/3 m/sec.   Let the length of the platform be x meters.   Then, x + 300 / 27   = 50/3   3(x + 300)   = 1350 è x   = 150m.   150mnswer:150m
