    Trains are running with speeds 30 km/hr and 58 km/hr in the same direction. A man in the slower train passes the faster train in 18 seconds. The length of faster train is

    A)  125 m   

    B)  140 m

    C)  150 m 

    D)  160 m

    Correct Answer: B

    Solution :

    [b] Distance travelled by slower train in 18 sec \[=30\times \frac{5}{18}\times 18=150\,m\] Distance travelled by faster train in 18 sec \[=58\times \frac{5}{18}\times 18=290\,m\] \[\therefore \] The length of faster train = 290 ? 150 = 140m
