pure milk costs Rs 20 per litre.after adding water the milkman sells the mixture at the rate of Rs 18 per litre, thereby making a profit of 25%. In what ratio does he mix the two?

• Let the volume of milk and water be x and y lit. resp.
  then, 20x=18(x+y)(100/125)
  So, x:y=18:7

  Let the volume of milk and water be x and y lit. resp.
  then,cost price for the milkman will be Rs. 20x and the selling price will be Rs.18(x+y),since now the total volume of the mixture is (x+y).
  Now C.P *(100+25)/100=S.P
  So 20x *(125/100)=18(x+y)
  =>x:y=18:7
