Ami is 8 years elder to her brother Amith. If the ratio of their ages is 7:3. Then find the sum of their present age.

Let age of Ami be $x$ yrs
then his brother is $x - 8$ yrs old

Now, $\frac{7}{3} = \frac{x}{x - 8} \Rightarrow 7 x - 56 = 3 x \Rightarrow x = 14$
$x - 8 = 14 - 8 = 6$

Sum of their age $= 14 + 6 = 20 y r s$
