How much 60% solution and how much 35% solution is needed to create 100 l of 40% solution?

Correct answer:

A =  20 l
B =  80 l

Step-by-step explanation:

p1=60%=60100=0.6 p2=35%=35100=0.35 p3=40%=40100=0.4  V=100 l   A+B=V A p1+B p2=V p3 A+B=100 A 0.6+B 0.35=100 0.4  A+B=100 0.6A+0.35B=40  A=20 l B=80
