Question
In container P, there is 110 litres of milk and in
container Q there is 70 litres of water. 30% of milk and 50% of water is taken out from the respective containers and are mixed in container R. How much water should be added to container R such that the ratio of milk to water becomes 3:4? MTSolution
Quantity of milk in container R = 0.30 × 110 = 33 litres Quantity of water in container R = 0.50 × 70 = 35 litres Let x litres of water is added to the container R. According to the question, 33/(35 + x) = 3/4 Or, 132 = 105 + 3x Or, 3x = 27 Or, x = 9 Therefore, water added to container R = 9 litres
