Answer:

Step-by-step explanation:

Assume as a basis  the final mixture is 1000 mL.  That means 399 mL of alcohol

Let x = mL of Soln A and y = mL of soln B.

x = 2y.

Now x + y = 1000

and  0.2x + 0.17y = 399

but x = 2y so 0.4y + 0.17y = 399

0.57y = 399.

y = 700 mL  (That is your mL of solution B)
