Let "x" be the amount of solution B, in milliliters.

Then the amount of the solution A is 4x milliliters, according to the condition.


The equation for the amount of the pure alcohol is


    0.15*(4x) + 0.19x = 395   millilites.


Simplify and find x


    0.6x + 0.19x = 395

    0.79x        = 395

        x        = 395/0.79 = 500  milliliters.    <U>ANSWER</U>
