# Six years ago, the ratio of the ages of Ram and Sai was 6 : 5. Four years hence, the ratio of their ages will be 11 : 10. What is Sai’s age at present ?

$\par&space;Let&space;the&space;ages&space;of&space;Ram&space;and&space;Sai&space;6&space;years&space;ago&space;be&space;6x&space;and&space;5x&space;years&space;respectively.$

$\frac{(6x&space;+&space;6)&space;+&space;4}{(5x&space;+&space;6)&space;+&space;4}&space;=&space;\frac{11}{10}$

$10(6x+10)&space;=&space;11(5x+10)$

$5x&space;=&space;10$
$x&space;=&space;2$

$\par&space;Sai's&space;present&space;age&space;=&space;(5x+6)&space;=&space;16&space;years.$
