Question

Arjun says his son ''four years ago, I was 4 times old as you were then and you was born when I was 27 years'' find the present age of arjun and his son

Answer 1

The present age of Arjun is 40 years and his son is 13 years respectively.

Step-by-step explanation:

Let the present age of son be “x” years old

It is given that Arjun was 27 years old when his son was born

So, Arjun's present age will be = (27 + x) years

Ages 4 years ago:

Arjun's age = (27+x) - 4 = (23 + x) years

Son's age = (x – 4) years

Also given, that 4 years ago, Arjun was 4 times as old as his son was then

So we can write eq. as,

(23 + x) = 4 * (x-4)

⇒ 23 + x = 4x - 16

⇒ 4x – x = 23 + 16

⇒ 3x = 39

⇒ x = 13 years ← Present age of son

∴ Arjun’s present age = 27 + x = 27 + 13 = 40 years

Thus, the present age of Arjun and his son are 40 years and 13 years respectively.
