• Suppose the vessel initially contains 8 litres of liquid.
  
  Let x litres of this liquid be replaced with water.
  
  Quantity of water in new mixture = 3 - 3x + x litres
  8
  Quantity of syrup in new mixture = 5 - 5x litres
  8
  3 - 3x + x = 5 - 5x
  8 8
  5x + 24 = 40 - 5x
  
  10x = 16
  
  x = 8 .
  5
  So, part of the mixture replaced = 8 x 1 = 1 .
  5 8 5
