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 Sagars age at present?
16 years
18 years
20 years
Cannot be determined
Explanation:
Let the ages of Kunal and sagar be x and y respectively.
According to the equation, (x-6)/(y-6) =6/5.
=> (x+4)/(y+4) =11/10.
After solving we get y=16.
