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

• ans.A
  (x-6)/(y-6)=6/5
  (x+4)/(y+4)=11/10
  after solving we get y=16

• Let Kunal's age=x Sagar's age=y
  x-6/y-6=6/5
  => 5x-6y=-6
  x+4/y+4=11/10
  => 10x-11y=4
  
  Hence, y=Sagar's age=16 years

• 16 year
  current age of kunal=x
  current age of sagar=y
  6 year ago=(x-6)/(y-6)=6/5
  after 4 year=(x+4)/(y+4)=11/10
  kunal=16
  sagar=12

• ans.18 years
  x=2then
  6x+6=18
• 13 years agoHelpfull: Yes(0) No(24)
• E. none of these
  ans will be 12 years
• 9 years agoHelpfull: Yes(0) No(5)
• A.16
  16-6=10 it's multiple of 5 which sagar age 6 years ago
  16+4=20 It's multiple of 10 which is Sager age after 4 years

• let 's' and 'k' be the present ages of sagar and kunal
  six years ago ,(s-6)/(k-6) = 6/5
  ===> 5s - 6k =-6 -----(1)
  Four years later, (s+4)/(k+4) = 11/10
  ====> 10s - 11y = 4 -----(2)
  solving (1) & (2)
  s=18, k=16
• 6 years agoHelpfull: Yes(0) No(0)
• Let the ages of Kunal and Sagar 6 years ago be 6x and 5x years respectively.
  
  Then, (6x + 6) + 4 = 11
  (5x + 6) + 4 10
  10(6x + 10) = 11(5x + 10)
  
  5x = 10
  
  x = 2.
  
  Sagar's present age = (5x + 6) = 16 years.
