    The speeds of two trains are in the ratio 6 : 7. If the second train runs 364 km in 4 h, then the speed of first train is

    A) 60 km/h

    B)  72 km/h

    C)  78 km/h

    D)  84 km/h

    Correct Answer: C

    Solution :

    Speed of second train \[=\frac{364}{4}=91\,\,\text{km/h}\] \[\therefore \]\[7x=91\] \[\therefore \] \[6x=\frac{91}{7x}\times 6x=78\,\,\text{km/h}\]
