    C)  ears                    

    D)         49 years

    Correct Answer: A

    Solution :

     Let the present ages of Priti and Asha be \[9x\] and \[13x\] years respectively. 8 years ago. \[\frac{9x\,\,\,\,\,8}{13x\,\,\,\,8}=\frac{7}{11}\] \[\Rightarrow \]\[99x-88=91x-56\] \[\Rightarrow \]\[99x-91x=88-56\] \[\Rightarrow \] \[8x=32\] \[\Rightarrow \] \[x=\frac{32}{8}=4\] \[\therefore \] Priti's present age \[=9x=9\,\,\,\,\,4=36\] years
