Question
Quantity of water in a 360 litres mixture (Milk +
Water) is 80 litres less than the quantity of milk in it. Find the quantity of water to be mixed so that the quantity of milk in the mixture becomes 55% of the whole mixture.Solution
Quantity of water in the mixture = {(360 - 80)/2} = 140 litres
So, quantity of milk in the mixture = (360 - 140) = 220 litres
Total quantity of the mixture if quantity of milk in the mixture becomes 55% = 220 Ă— (100/55) = 400
So, quantity of water needs to be mixed = (400 - 360) = 40 litres
