. 1st a story. Then a simple ratio problem. The question was if the ratio of age of two persons is 5:6, sum of present age is 33, and then in how many years the ratio of their age becomes 7:8?

• 5x:6x
  and 5x+6x=33
  so, x=3
  present age are 15 and 18
  now, 15+x:18+x=7:8
  x=6
  so 6 is the answer

• 5x+6x=33
  11x=33
  x=3
  therfore 5x=15 and 7x=21
  therefore, after 6yrs the ratio becomes 7:8
  
  Ans: 6 yrs

• 6 years
  
  If present ages are 5x and 6x, then 5x+6x=33, x=3
  So their present ages are 15 and 18 years.
  If after 'a' years the ratio of their age becomes 7:8, then (15+a)/(18+a)=7/8, 120+8a=126+7a, a=6

• assume in x yrs ratio of age becomes 7:8.
  5+x/6+x=7:8
  x=2 ans
• 8 years agoHelpfull: Yes(0) No(2)
