Question 409872: How many liters of a 70% alcohol solution must be added to 50 liters of a 40% alcohol solution to produce a 30% alcohol solution? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! The setup is this:
x(.70) + 50(.40) = (x+50)(.30)
What a minute...this is impossible...you cannot add a 70% solution to a 40% solution and expect it to be more dilute...trick question!
