A vessel is filled with liquid, 3 parts of which are water and 5 parts syrup, How much of the mixture must be drawn off and replaced with so that the mixture may be half water and half syrup ?

• Here totally 8 parts (5 part syrup + 3 part water).
  
  To make it equal (4 parts syrup + 4 part water).
  
  So, we have to draw 1 part from syrup (i.e.,) 1/5.
