Produced 3333

How much 55% alcohol do we need to add to 1500 grams of 80% alcohol to produce 60% alcohol? How much is 60% of alcohol produced?

Correct answer:

a =  6000 g
b =  7500 g

Step-by-step explanation:

0.55a + 1500·0.80 = (a+1500)·0.60

0.55·a + 1500·0.80 = (a+1500)·0.60

0.05a = 300

a = 300/0.05 = 5999.99999999

a = 6000

Our simple equation calculator calculates it.
b=a+1500=6000+1500=7500 g
