    Question

    A train passes an electrical pole in 14 seconds and

    passes a platform 360 m long in 50 seconds. Find the length of the train.
    A 160 m Correct Answer Incorrect Answer
    B 140 m Correct Answer Incorrect Answer
    C 180 m Correct Answer Incorrect Answer
    D 150 m Correct Answer Incorrect Answer

    Solution

    Let the length of the train be ‘x’ meter. ∴  x/14 = (x + 360)/50 ⇒  50x = 14x + 5040 ⇒  36x = 5040 ⇒  x = 140 m
