The ratio of the present age of Mahesh and Ajay is respectively 3 : 2. After 8 years, ratio of their age will be 11 : 8. What will be the present age of Mahesh’s son if his age is half of the present age of Ajay?1). 12 years2). 24 years3). 18 years4). 9 years

Answer»

Let present age of Mahesh is X years

Let present age of Ajay is y years

⇒ x : y = 3 : 2

3Y = 2x---(i)

After 8 years

⇒ (x + 8) : (y + 8) = 11 : 8

8X + 64 = 11y + 88

⇒ 8x = 11y + 24---(ii)

From eq (i) and (ii), we get,

⇒ y = 24

⇒ x = 36

∴ Age of Mahesh’s son = 24/2 = 12 years
