Question
A man initially has a mixture of milk and water, with
80% of the mixture being milk. He sells 20 litres of this mixture and replaces it with the same amount of water. After this, the quantity of water in the mixture becomes 40 litres. What was the total quantity of the original mixture?Solution
Quantity of water in the mixture before 20 litres water was added = 40 - 20 = 20 litres Quantity of water in the 20 litres mixture that was sold = 20 X 0.2 = 4 litres So, total quantity of water in the original mixture = 20 + 4 = 24 litres So, total quantity of original mixture = 24 Ă· (1 - 0.8) = 120 litres
