 Question 363416: An amount of 40% acid solution is to be mixed wih enough 10% acid solution to make 25% acid solution. If there are to be 2o liters of the final mixture, how much of each solution should be mixed together?Found 2 solutions by josmiceli, Alan3354:Answer by josmiceli(9681)   (Show Source): You can put this solution on YOUR website!Let = liters of 40% solution needed Let = liters of 10% solution needed given: = liters of alcohol in 40% solution = liters of alcohol in 10% solution = liters of alcohol in final solution -------------------- (1) (2) from (1) (1) (1) Subtract (2) from (1) and 1 liter of 40% solution and 1 liter of 10% solution are needed check: (1) (1) OK Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!Since 25% is the average of 10% and 40%, it's equal amounts. Either 1 liter or 10 liters of each, depending on what 2o means.
