    Question

    Train тАШAтАЩ running with a speed of 126 km/hr can

    cross a standing goods train of 4 times its length in 25 seconds. Find the time taken by 500 metres long train тАШBтАЩ which is coming from opposite direction of train тАШAтАЩ, with a speed of 10 m/s, to cross train тАШAтАЩ.
    A 15 seconds Correct Answer Incorrect Answer
    B 5 seconds Correct Answer Incorrect Answer
    C 14 seconds Correct Answer Incorrect Answer
    D 10 seconds Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the length of train тАШAтАЩ be тАШxтАЩ metres Therefore, length of the goods train = тАШ4xтАЩ metres Speed of train тАШAтАЩ = 126 ├Ч (5/18) = 35 m/s According to the question, 4x + x = 35 ├Ч 25 => 5x = 875 => x = 175 Therefore, time taken by train тАШBтАЩ to cross train тАШAтАЩ = {(175 + 500)/(35 + 10)} = 15 seconds
