Question
A tank initially contains a water-alcohol mixture in a
7:3 ratio. After removing 20 liters of the mixture and replacing it with pure alcohol, the ratio becomes 1:1. Determine the tank's total capacity.Solution
SOLUTION: Let initially container contains 7x liters of water and 3x liters of alcohol After 20 liters of this mixture are replaced with alcohol then, 
 = 1/1 
 = 1/1 Cross-multiplying- 70x-140 = 30x+140 40x = 280 x = 7 the total volume of the tank = 10x = 70 liter
