Question

The sum of ages of a father and son is 40 years if father is three times that of his son then find ages

Answer 1

Answer :

• Age of father = 30 years.
• Age of son = 10 years.

Step - by - step explanation :

Let the age of father be x years and the son be y years.

Given,

• x + y = 40 → (1)
• x = 3y → (2)

$\hrulefill$

Substituting (2) in (1) ⇒ 3y + y = 40

⇒ 4y = 40

⇒ y = 10

Substituting the value of y in (2) ⇒

⇒ x = 3 × 10

⇒ x = 30

∴ age of father = 30 years.

age of son = 10 years.
