Forget the volumes for the time being.You have to mix 20% and 80% solutions to get 50%.&nbsp;This is very straightforward since 50 is in the middle of 20 and 80, so we need both solutions in equal quantities. If this doesn&#x27;t strike, usew1/w2 = (A2 - Aavg)/(Aavg - A1)w1/w2 = (80 - 50)/(50 - 20) = 1/1So the volume of the two solutions will be equal.&nbsp;The answer has to be 4:4.Answer. C
