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?
A. 16 years B. 18 years
C. 20 years D. Cannot be determined
E. None of these

• six year ago; Kuanl age = 6x & Sagar age = 5x
  present age; Kuanl age = 6x+6 & Sagar age = 5x+6
  four year hence; Kuanl age = 6x+6+4 & Sagar age = 5x+6+4
  ratio will be; (6x+10)/(5x+10)=11/10
  x=2;
  present age of Sagar = 5x+6=16 year

• 2 is coming alternatively so others are decrement by 2.
  10,8,6,4
  so the series will be 10,2,8,2,6,2,4

• Let present age of kunal = x
  let present age of sagar = y
  
  ATQ, (x-6) / (y-6) = 6 / 5
  (x+4) / (y+4) = 11/ 10
  solving , we get y = 16
  thus, A. 16 years

• (6x+6)+4/(5x+6)+4=11/10
  by solving we get x=2
  age of sagar at present is 5x+6=16
