A train crosses a tunnel of 1200 m in 45 sec, same train crosses another platform of length 180 m in 15 sec. then find the length of the train?  Choose the correct choice from the following:
A) 350m
B) 400m
C) 272m
D) 330m
E) 267m
Length of the train be ‘X’   (X + 1200)/45 = (X + 180)/15   X + 1200 = 3X + 540   2X = 660   X = 330m   Answer: 330m
