    Four years ago the ratio between the ages of Suresh and Deena was 5 : 3 respectively. The ratio between their present ages is 11 : 7 respectively. What will be Deena's age 3 years hence?

    A)  34 years

    B)  29 years

    C)  33 years

    D)  31 years

    E)  None of these

    Correct Answer: D

    Solution :

     Let the ages of Suresh and Deena four years ago be 5x and 3xyears respectively. \[\therefore \]\[\frac{5x+4}{3x+4}=\frac{11}{7}\] \[\Rightarrow \]\[35x+28=33x+44\] \[\Rightarrow \]\[35x-33x=44-28\] \[\Rightarrow \]\[2x=16\Rightarrow x=8\] \[\therefore \]Deena?s age 3 years hence \[=3x+7\] \[=3\times 8+7=31\]years
