Alcohol 4441

How much 55% alcohol do we need to add to 2 liters of 80% alcohol to produce 60% alcohol? How much is 60% of alcohol made?

Correct answer:

a =  8 l
b =  10 l

Step-by-step explanation:


0.55a+0.80•2=0.6•(a+2)

0.55•a+0.80•2=0.6•(a+2)

0.05a = 0.4

a = 8

Our simple equation calculator calculates it.
b=2+a=2+8=10 l
