Question

    A train running with a speed of 54 km/hr can cross a

    pole in 15 seconds and a platform in 22 seconds. Find the length of the platform.
    A 105 metres Correct Answer Incorrect Answer
    B 100 metres Correct Answer Incorrect Answer
    C 115 metres Correct Answer Incorrect Answer
    D 95 metres Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Speed of the train = 54 × (5/18) = 15 m/sec Length of the train = 15 × 15 = 225 metres Let the length of the platform be ‘x’ metres Therefore, 225 + x = 15 × 22 Or, x = 330 – 225 = 105 metres
