Solution of algebraic expressions.

(Addition, subtraction, multiplication, and division).

Given:

Shanu's age three years ago = m years

Find:

The present age of Varun.

Solution:

Let the present age of Varun be x years.

Shanu's present age = Shanu's age three years ago + 3

                                   = (m + 3) years

According to question, Varun's present age, x = Thrice that of Shanu's present age

x = Three times Shanu's present age

x = 3 × (m + 3)

x = 3(m + 3)

x = 3m + 9

x = (3m + 9) years

Hence, Varun's present age = x = (3m + 9) years.
