    The difference between the present ages of Anil and Sudhir is 6 yr. The ratio between their ages after 4 yr will be 3:4. What can be the present age of Sudhir?

    A) 15 yr

    B)  18 yr

    C)  20 yr   

    D)  24 yr

    Correct Answer: C

    Solution :

    Let Anil's age be x yr and Sudhir's age = (x + 6) yr. Then,    \[\frac{x+4}{(x+6)+4}=\frac{3}{4}\] \[\Rightarrow \]   \[\frac{x+4}{x+10}=\frac{3}{4}\] \[\Rightarrow \]   \[4\,\,(x+4)=3\,\,(x+10)\]\[\Rightarrow \]\[x=14\] Sudhir's present age = (14 + 6) yr = 20 yr
