Question

Q.9: Ali is x years old. Express the following using variables.
a) Ali's age 5 years ago.
b) 4 times Ali's age 3 years hence
c) The present age of Ali's father who is 6 times as old as Ali, 5 years.​

Answer 1

Let Aman's son's present age =x

According to the question, Aman's present age =3x

Given, ten years ago,

Aman's age =3x−10

Aman's son age =x−10

Aman's age =5 × Aman's son's age

∴3x−10=5(x−10)

Step 2: Solve the above equation

⇒3x−10=5x−50

⇒5x−3x=50−10

⇒2x=40

⇒x=20.

So, Aman's son's age =x=20 years

Aman's age =3x=3×20=60 years.

Therefore, the present ages of Aman and his son are 60 and 20 years.
