◀HERE'S YOUR ANSWER▶

Age of Leena : Age of Heena = 7 : 5
Let, common ratio = x

Then, present age of Leena = 7x years
and present age of Heena = 5x years

Given that
(7x + 10) : (5x + 10) = 9 : 7
$\frac{7x + 10}{5x + 10} = \frac{9}{7}$
⏩ 49x + 70 = 45x = 90
⏩ 4x = 20
⏩ x = 5

So, the present age of Leena = 35 years
and the present age of Heena = 25 years
