Suppose the age of Ravi is p and age of Arun be m.

  • According to the condition we have :-

p = 6m (Assume it equation 1)

  • Now afterwards 18 years :-

⇒ (p + 18) = 3(m + 18)

⇒ p + 18 = 3m + 54

⇒ p - 3m = 54 - 18

⇒ p - 3m = 36

p - 3m - 36 = 0 (Assume it equation 2)

  • Now solve (1) and (2) we get :-

⇒6m - 3m = 36

⇒3m = 36

⇒ m = 36 ÷ 3

⇒ m = 12

  • Put the value of m in (1) we get :-

⇒ p = 6m

⇒ p = 6(12)

⇒ p =  72

Ravi present age is 72 years
