6 liters of brand A fruit punch must be mixed with 9 L of brand b fruit punch.
Let x=liters of Brand A fruit punch to be mixed with 9 liters of Brand B fruit punch.
x + 9 = liters of mixture.
20%(x) + 9*40% = 32%(x+9)
20/100 x + 9*40/100 = 32/100 (x+9)
0.2x + 360/100 = 0.32x + 9*0.32
0.2x + 3.6 = 0.32x + 2.88
0.12x = 3.6 - 2.88
0.12x = 0.72
divide by 0.12 on both sides
x = 0.72/0.12
= 72/100/12/100
= 72/12
= 6 liters.
Therefore 6 liters of brand A fruit punch must be mixed with 9 L of brand b fruit punch.
