Answer 1

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed{ \boxed{\boxed { \huge \sf \purple{ Solution}}}}$

Let A's age be 7x

and B's age be 5x

After 10 years,

A's age = 7x + 10

B's age = 5x + 10

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

$\mathrm {49x+70=45x+90}\\\\\\\mathrm {4x=20}\\\\\\\mathrm {x=5}$

A's present age = 7 × 5 = 35

B's present age = 5 × 5 = 25

• AGE OF A= 35 YEARS
• AGE OF B= 25 YEARS
