A spirit and water solution is sold in a market. The cost per liter of the solution is directly proportional to the part (fraction) of spirit (by volume) the solution has. A solution of 1 liter of spirit and 1 liter of water costs 50 cents. How many cents does a solution of 1 liter of spirit and 2 liters of water cost?  Choose the correct choice from the following answers.
A) 13 B) 33 C) 50 D) 51 E) 52
The cost per liter of the solution is directly proportional to the part (fraction) of spirit (by volume) the solution has.   It means there is no effect of change in volume of water to the costing of the solution   So a solution of 1 liter of spirit and 2 liters of water will cost 50 cents   Answer = 50   ANSWER:50
