Answer 2

$\huge\boxed{\mathtt\red{Solution :-}}$

Given :-

• Ratio of present age of Sonal and Manoj is 7:5
• Ratio of their ages after 10 years is 9:7

To Find :-

• Their present ages

Assumption :-

• Let their present ages be 7x and 5x

Solution :-

After 10 years :-

$\large\boxed{\implies\mathtt\blue{\frac{7x+10}{5x+10}=\frac{9}{7}}}$

$\large{\implies\mathtt\blue{49x+70=45x+90}}$

$\large{\implies\mathtt\blue{49x-45x=90-70}}$

$\large{\implies\mathtt\blue{4x=20}}$

$\large\boxed{\mathtt\blue{∴x=5}}$

Answer :-

The present age of :-

$\large\boxed{\mathtt\green{Sonal = 7x = 7×5 = 35\: years}}$

$\large\boxed{\mathtt\green{Manoj = 5x = 5×5 = 25 \:years}}$
