    Question

    A train passes an electrical pole in 18 seconds and

    passes a platform 350 m long in 60 seconds. Find the length of the train.
    A 140 m Correct Answer Incorrect Answer
    B 160 m Correct Answer Incorrect Answer
    C 120 m Correct Answer Incorrect Answer
    D 150 m Correct Answer Incorrect Answer

    Solution

    Let the length of the train be ‘x’ meter. ∴ x/18 = (x + 350)/60 ⇒ 60x = 18x + 6300 ⇒ 42x = 6300 ⇒ x = 150 m
