a milkman makes 20% profit by selling milk mixed with water at rs 9 per liter.if the cost price of 1 liter pure milk is rs 10,then the ratio of milk and water in the mixture.

• cost price=sp*100/120
  cp=9*120/100=7.5
  in 10 rps we get 1000ml of milk...
  so in 7.5rps ----->1000*7.5/10=750ml of milk
  750:250=3:1
