    A starts from a place P to go to a place Q. At the same time B starts from Q to P. If after meeting each other A and B took 4 and 9 h more respectively to  reach their destinations, the ratio of their speeds is  

    A) 3 : 2     

    B)  5 : 2   

    C)  9 : 4    

    D)  9 : 13

    Correct Answer: A

    Solution :

    If two persons start at the same time from two points A and B towards each other and after crossing they take a and b hours in reaching B and A respectively, then \[\frac{\text{A }\!\!'\!\!\text{ s}\,\,\text{speed}}{\text{B }\!\!'\!\!\text{ s}\,\,\text{speed}}=\frac{\sqrt{b}}{\sqrt{a}}=\frac{\sqrt{9}}{\sqrt{4}}=\frac{3}{2}\]
