    A train passes a pole in 10 seconds and passes a 120m-long platform in 20 seconds. Find its length.

    A)  120m              

    B)  160m  

    C)         125m  

    D)         135m  

    E)         None of these

    Correct Answer: A

    Solution :

    Let the length of the train be x m. Then, \[\frac{x}{10}=\frac{x+120}{20}\] or, \[2x=x+120\] or, \[x=120\,\,m\] \[\therefore \]Length of the train \[=120\,\,m\]             Logical Approach: \[T\to \]in 10 sec \[T+120\,\,m\to \]in 10 sec \[\Rightarrow \]\[120\,\,m\to \]in 10 sec \[\Rightarrow \]\[T=120\,\,m\]
