the ages of A and B are in the ratio of 8:5.if the sum of their ages is 39 years,what will be the ratio of their ages after 9 years?

• 8x+5x=39
  13x=39
  x=39/13=3
  a=24,b=15
  after 9 yr,a=33,b=24
  so a:b::11:8

• 11:8. 5A=8B, A+B=39 SOLVING BOTH EQNS, A=24 AND B=15 YEARS. AFTER 9 YEARS A=24+9=33, B=15+9= 24. SO A:B = 33:24 :: 11:8
• 8 years agoHelpfull: Yes(3) No(0)
• 8x+5x=39
  x=3;
  after 9 yr
  (8*3)+9:(5*3)+9
  11:8

• ratio of A and B=8:5 and their sum=39=>8x+5x=13x=39=>x=3
  therefore ages of A and B is 24 and 15
  after 9 years ratio of their ages are 33:24=>11:8

• Let us assume the x
  8*x+5*x=39
  13x=39
  X=3
  At present their ages are in the ratio A:B=24:15
  So after 9 years there should be in the ratio A:B is 33:24

• 33:24

• A : B = 8:5
  or
  A/B=8/5
  
  => 8X+ 5X = 39
  => 13X= 39 or X=3
  
  therefore => age of A = 8X=24 (current)
  and age of B = 5X = 15(current )
  
  ratio after 9 years = (8X +9) : (5X +9)
  
  hence answer = 33 : 24
