Question
Quantity of water in a 300 litres mixture (alcohol +
water) is 40 litres less than the quantity of alcohol in it. Find the quantity of water to be mixed so that the quantity of alcohol in the mixture becomes 50% of the whole mixture.Solution
Quantity of water in the mixture = (300 β 40)/2 = 130 litres So, Quantity of alcohol in the mixture = (300 β 130) = 170 litres Total quantity of the mixture = 170 x (100/50) = 340 litres Therefore, quantity of water to be mixed = 340 β 300 = 40 litres
