Question

Prathima's age is 4 times the age of her son. Find the son's age if the sum of their ages is 40 years.

• A. 8
• B. 4
• C. 3
• D. 2

Answer 1

The correct option is A

8

Let the age of the son = x years

$\therefore$ Age of Prathima is 4 times the age of the son = 4x years.

age of the son = 4x years.

Sum of their ages = 40 years

$x+4x=40$

$5x=40$

$x=8$

$\therefore$ Son's age = x years = 8 years.
