Six years ago, the ratio of ages of Kunal and Sagars was 6 : 5. Four years hence, the ratio of their ages will be 11 : 10. what is Sagar's age at present ?

  • A. 18 years
  • B. 18 years
  • C. 18 years
  • D. 18 years

Answer: Option C

Explanation:

Let the ages of Kunal and Sugar 6 years ago be 6x and 5x years respectively.
Then, {(6x + 6) + 4}/{(5x + 6) + 4} = 11/10
⇒10(6x + 10) = 11(5x + 10)
⇒5x = 10
⇒x = 1
∴ Sagar's present age = (5x + 6) = 16 years.
