Find the dilution.

Question

You have a 55 gallon drum full of product A. You take 33 gallons of product A and mix it with 22 gallons of water to make 55 gallons of product B. You take 22 gallons of product B and 33 gallons of water to make 55 gallons of product C. How many gallons of product A does it take to make 55 gallons of product C?

Answer 1

The answer you need is Gallons-A per Gallons-C

You are given Gallons-A per Gallons-B (33/55, here).

You are also given Gallons-B per Gallons-C (write your number, here).

Use the formula:

Gallons-A per Gallons-C = (Gallons-A per Gallons-B) multiply by (Gallons-B per Gallons-C) (Write your number, here).

Finally to make 55 Gallons of C; multiply the previous number by 55.

Answer 2

55 gallons of product C requires 22 gallons of product B.

 

55 gallons of product B requires 33 gallons of product A

 

22 gallons of product B requires = (33/55)*22 = 13.2 gallons of product A

 

So, 55 gallons of product C requires 13.2 gallons of product A.

 

The answer is 13.2 gallons of product A
