Question
The ratio of liquor and soda in a mixture of 50 liters
is 3:2. How much soda should be mixed to make the ratio 6:7?Solution
Total mixture = 50 liter Liquor              soda 3         :          2 30                   20 6         :          7 Let x liters of soda be added to the mixture. 30/20+x = 6/7 210 = 120+6x 6x = 90 X = 15 liter
