A dishonest person wants to make a profit on the selling of milk. He would like to mix water (costing nothing) with milk costing 33 $ per litre so as to make a profit of 20% on cost when he sells the resulting milk and water mixture for 36$. In what ratio should he mix the water and milk?	Select: A) 1:20 B) 1:10 C) 1:8 D) 1:4 E) 1:2
He needs to make a profit of 20%, which means he needs to sell the milk +water combination for 39.6 (20% of 33 +33)   Now, he plans to sell 1 liter of this solution of milk and water for 36. which means he needs to sell 1.1 liters of this solution to earn 39.6. (36 for 1 liter and so 39.6 for 1.1 liters)   Hence the water added would be .1 liter.   Therefore the ratio of water to milk is .1/1 = 1/10   ANSWER:1:10
