    At present, the ratio of the ages of Maya and Chhaya is \[6:5\] and fifteen years from now, the ratio will get changed to\[9:8\]. Maya's present age is

    A)  21 years                      

    B)  24 years

    C)  30 years            

    D)  40 years

    Correct Answer: C

    Solution :

     Let Maya's present age be \[6x\] years and Chhaya's present age be \[5x\] years. After 15 years,             \[\frac{6x+15}{5x+15}=\frac{9}{8}\] \[\Rightarrow \]   \[48x+120=45x+135\] \[\Rightarrow \]   \[48x-45x=135-120\] \[\Rightarrow \]   \[3x=15\Rightarrow x=5\] \[\therefore \]Maya?s present age\[=6x\]             \[=6\times 5=30\]years
