the ratio of ritas age to her mothers age is3:8 the difference of their ages is 35 years the ratio of their ages after 4 years will be

• 5:12
  
  Let the present age of Rita=x and her mother=y years, then
  Ratio of their age = x/y=3/8 => 8x - 3y = 0 ---(i)
  Difference of their age = y - x = 35 ---(ii)
  Solving equation (i) & (ii), we get x=21, y=56
  So, ratio of their ages after 4 years = (x+4)/(y+4) = (21+4)/(56+4) = 25/60 = 5/12

• Let Rita’s age be 3x
  
  Let her mother’s age be 8x
  
  Difference in ages = 35
  
  8x-3x=35
  
  5x=35
  
  x=7
  
  Rita’s age is 21 years
  
  Her mother’s age is 56 years
  
  After 4 years
  
  Her age is 25
  
  Her mother’s age is 60
  
  The ratio of her age to her mother’s age after 4 years will be
  
  5:12
