    Train A running at 90 kmph takes 12 seconds to cross a pole how much time (in sec) will train B running at the speed of 36 kmph take to cross the pole, if its length is 50% more than that of train A?

    A)  25 seconds                   

    B)  30 seconds       

    C)  40 seconds       

    D)         45 seconds       

    E)         36 seconds

    Correct Answer: D

    Solution :

    Length of train A \[=90\times 12\times \frac{5}{18}\] = 300m Now, length of train B \[=300\times \frac{150}{100}=450m\]  \[\therefore \]Time taken by Train B to cross the pole \[=\frac{450\times 18}{36\times 5}=45\]Seconds
