Milk and Water Puzzle


Let’ suppose we have in one glass a certain quantity of water and in another glass an equal quantity of milk (unwatered milk). We take a teaspoonful of milk from first glass, put it in the second and stir. We then take a teaspoonful of the mixture from the second glass and put it back in the first glass. Now is there more water in the milk than milk in the water, or more milk in the water than water in the milk?

  1. If the answer is abt quantity in ml then the answer will be both are same……But when considering the amount of substance or molecules then obviouly 2nd answer…more milk in the water than water in the milk………

  2. Solution: Well, suppose for simplicity that we start with 4 teaspoonfuls of each milk and water. If we put one teaspoonful of milk in water, the resulting five teaspoonfuls of mixture is 1/5 milk and 4/5 water. When we transfer one teaspoon of mixture to the glass of milk, we are returning 1/5 teaspoonful of milk – thus leaving 4/5 teaspoon of milk in the water and are adding 4/5 of a teaspoon of water in the milk. Thus there are equal quantities 4/5 of a teaspoonful – of milk in water and water in milk. Incidentally, it makes no difference whether or not we stir the mixture!
