Question : 56
Total: 100
A man divided an amount between his sons in the ratio of their ages. The sons received Rs. 54000 and Rs. 48000. If one son is 5 years older than the other, find the age of the younger son.

48 years
54 years
Validate
Solution:
Let the son’s ages be ‘x’ years and ‘y’ years
Given, x - y = 5
⇒ x = y + 5
Now,
Ratio of their shares = ratio of their ages
⇒ 54000 ∶ 48000 = x ∶ y
⇒ 9 ∶ 8 = (y + 5) ∶ y
⇒ 9y = 8y + 40
⇒ y = 40
∴ The younger son’s age is 40 years
