Answer 1

Given :

• Rakesh is twice as old as his cousin.

• After 4 years the ratio of their ages will be 3:2.

To find :

• Their present ages =?

Step-by-step explanation :

Let, the present age of Rakesh's cousin be x.

Then, the present age of Rakesh's be 2x.

After 4 years age of Rakesh's cousin = x + 4

After 4 years age of Rakesh's = 2x + 4.

According to the question :

➮ 2x + 4/x + 4 = 3/2

➮ 2(2x + 4) = 3(x + 4)

➮ 4x + 8 = 3x + 12

➮ 4x - 3x = 12 - 8

➮ x = 4

Therefore, We got the value of, x = 4.

Hence,

The present age of Rakesh's cousin = 4 years

The present age of Rakesh's = 2x = 2 × 4 = 8 years
