According to the question, you want to make 200 6 ounce servings of OJ or 100 12 ounce servings.
The ratio is 1:3. 1 part concentrate to 3 parts water.
Therefore
1/4 * 100 = 25 cans of concentrate & 75 cans of water to make 1200 ounces of OJ.
Answer would be A.
OG math.

First, find out how much total juice you need:
200 total cans, 6 oz. each = 1,200 oz. of total juice.
Since you need 1 oz. of concentrate for every 4 oz. of juice, then for 1,200 oz. you need 300 oz. of concentrate (think 1/4 = x/1,200, solve for x).
So, since the questions says that concentrate comes in 12 oz. cans, how many cans do you need to equal 300 oz. of conentrate? 12/300 = 25 cans. The answer is A.
Remember not to "cross the streams" when they throw around different container sizes.
