• # question_answer The ratio between Priti's and Asha's ages is 9 : 13 respectively. 8 years ago the ratio between their ages was 7: 11 respectively. What is Priti's present age? A)  36 years                       B)  52 years C)  ears                     D)         49 years

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
