Answer 2

Answer :

Adarsh = 20 years

Talo = 28 years

Explanation :

Let the age be ' x '

So, Adarsh = 5x

Talo = 7x

Four years later :

Age of Adarsh will be = 5x + 4

Age of Talo will be = 7x + 4

According to the question :

5x + 4 / 7x + 4 = 3 : 4

=> 5x + 4 / 7x + 4 = 3 / 4

=> 4 ( 5x + 4 ) = 3 ( 7x + 4 )

=> 20x + 16 = 21x + 12

=> 21x - 20x = 16 - 12

=> 1x = 4

=> x = 4

To find :

Adarsh = 5x = 5 × 4 = 20

Talo = 7x = 7 × 4 = 28

❥ So, It's Done ❥ !!
