===================================


$\frac{7x + 10}{5x + 10} = \frac{9}{7}$



$7(7x + 10) = 9(5x + 10)$




$49x + 70 = 45x + 90$




$49x - 45x = 90 - 70$




$4x = 20$




$x = \frac{20}{4} = 5$


so, x=5


Now , leena's age is 7x =
$7 \times 5 = 35years$




Now , heena's age is 5x =

$5 \times 5 = 25years$

Answer 2

Hey mate,

Let the ratio of the present ages of leena and heena be 7x and 5x respectively...

Now,

According to the question,

10 yrs hence, age of leena=7x+10

10 yrs hence, age of heena=5x+10

So,

7x+10/5x+10=9/7

Or,49x+70=45x+90

Or, 4x=20

X=5

So, present age of leena =7x =35yrs

Present age of heena=5x=25yrs
