Answer:

Explanation:

Given,

The ratio of the Present Ages of Viju to that of Aju is 7 : 2.

Four years from now, the ratio of the Ages of viju to aju will be 5 : 2.

To find,

Viju's Age 6 years Ago

Let,

Present Age of Viju = 7x years

Present Age of Aju = 2x years

《After 4 Years》

Age of Viju = (7x + 4) years

Age of Aju = (2x + 4) years

According to question :-

7x+4/2x+4 = 5/2

=> 2(7x+4) = 5(2x+4)

=> 14x+8 = 10x+20

=> 14x - 10x = 20 - 8

=> 4x = 12

=> x = 12/4

=> x = 3

So,

Present Age of Viju = 7 × 3 = 21 years

《 6 Years Ago 》

Viju's Age = 21 - 6

Hope my answer have helped you.

Thanks
