66. The ages of two people has the ratio of 6:5 and by adding the numbers we get 55 , after how many years the ratio would be 8:7?

• ratio of age = 6:5
  let the ages be 6x,5x
  6x+5x=55
  11x=55
  x=5
  ages are 30 and 25
  let n be the no. of years
  (30+n):(25+n)=8:7
  solving we get n=10

• Current age is 30 and 25
  so after 10 years age will be 40 and 35 i.e the ratio will 8:7
  So the Answer = 10 years

• let us assume,both ages be 6x,5x..,by adding both we get 11x=55 that means x=5 then by multiplying we get 30,25 now we say let n be the no of years then we get (30+n):(25+n)=8:7
  =>210+7n=200+8n
  =>n=10

• 10 a=30 b=25 after 10 years a=40 b=35 a:b 8:7

• x/y=6/5,x+y=55
  y=25,x=30
  x=10

• 10 years..
  6x : 5x
  6x+5x=55 => x=5 i.e. 6x=30 and 5x=25
  8x=40 and 7x=35
  so diff is 10 years
