A 300 meter long train crosses a platform in 30 seconds while it crosses a signal pole in 18 seconds. What is the length of the platform?	Answers:
A) 227 B) 266 C) 230 D) 288 E) 200
Speed = [300 / 18] m/sec = 50/3 m/sec.   Let the length of the platform be x meters.   Then, x + 300 / 30 = 50/3   3(x + 300) = 1500 è x = 200m.   Answer: 200
