The present age of Salil's mother is three times Salil's present age. After 5 years, their ages Class 9

Question 1.

The present age of Salil's mother is three times Salil's present age. After 5 years, their ages will add up to 70 years. Find their present ages. Class 9

Solution:

Let Salihs present age be x year.

∴ Salihs mother's present age = 3x year After 5 years,

∴ Salihs age = x + 5 years and his mother's age = 3x + 5 years.

According to the given condition,

(x + 5) + (3 + 5) = 70

∴ x + 5 + 3x + 5 = 70

∴ 4x + 10 = 70

∴ 4x = 60

∴ x = [latex]\frac{60}{4}[/latex]

∴ x = 15 years

∴ Salihs present age is 15 years.

Salihs mother's present age = 3x = 3(15)

= 45 years.

∴ Salihs mother's present age is 45 years.
