Question
Quantity of water in a 280 litres mixture (Milk + Water)
is 40 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 40% of the whole mixture.Solution
Quantity of water in the mixture = {(280 - 40)/2} = 120 litres
So, quantity of milk in the mixture = (280 - 120) = 160 litres
Total quantity of the mixture if quantity of milk in the mixture becomes 40% = 160 × (100/40) = 400
So, quantity of water needs to be mixed = (400 - 280) = 120 litres
