Comprehension Passage
Directions: Study the graph carefully to answer the following question.
A solution X contains syrup and soda in the ratio 5:4, and this solution X is mixed in the ratio 3:1 with another solution of syrup and soda, where the ratio of syrup to soda is 1:2, forming solution Y. Solution X and Y are further mixed in the ratio 9:2 to form solution Z, and this solution Z is mixed in the ratio 11:10 with another solution of syrup and soda, where the ratio of syrup to soda is 3:7, forming solution W. Solution Y and W are mixed in the ratio 6:7 to form another solution V.
From 80 liters of solution Y, 20 liters of mixture is removed and replaced with the same amount of soda. Again, 20 liters of the mixture is taken out and replaced with the same amount of pure syrup. Now, if this solution is sold at the price of pure syrup, what will be the final ratio of syrup to soda?
