Initially 5% is the portion of the water in the mixture,95% is the portion of the milk in the mixture. So quantity of water(in litres) in the 10 L=0.05*10L=>0.5L. And also quantity of milk in 10 L mixture=0.95*10L=9.5L. Let X be the quantity of pure milk to be added to the mixture to make water content to 2%. Therefore, 0.5/(9.5+X)=0.2/9.8 9.8*0.5=0.2(9.5+X) 4.9=1.9+0.2X 0.2X=3.0 x=15 So 15 Liters of pure milk should be added to the mixture to reduce the water content to 2%
