Question

Anu is four years older than Sunil. Eight years ago, Anu was three times Sunil's age.
Find the ages of Sunil and Anu.​

Answer 1

Answer: Sunil's age = 10years, Anu's age = 10+4 = 14years.

Explanation:

Anu is four years older than Sunil

If Sunil's age = x

Anu's age = x+4

Anu was 3 times Sunil's age 8 years ago

(x+4) - 8 = 3(x-8)

⇒ x - 4 = 3x - 24

⇒ x - 3x = -24 + 4

⇒ -2x = -20

⇒ x = -20/-2 = 10

Sunil's age = 10years

Anu's age = 10+4 = 14years
