A train crosses a platform of 150 m in 15 sec, same train crosses another platform of length 200 m in 18 sec. then find the speed of the train?
Choices:
A) 40/3 m/sec	B) 37/3 m/sec	C) 50/3 m/sec	D) 41/3 m/sec	E) 55/3 m/sec
Length of the train be ‘X’   (X + 150)/15 = (X + 200)/18   6X + 900 = 5X + 1000   X = 100m   Speed = (100+150)/15 = 50/3 m/sec   Answer: 50/3 m/sec
<result>C</result>
