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

Answer»

Let the ages of kunal and sagar before 6 YEARS be 6a and 5a

Kunal's age after four years = 6a + 10

Sagar's age after four years = 5a + 10

According to question,

( 6a + 10) /(5a + 10) = 11 /10

=> 60a + 100 = 55A + 110

=> 5a = 10

=> a = 2

Sagar's present age = 5 (2) + 6

= 10 + 6

= 16 years
