This is a Gmat prep question. I dont know how to attach wrong answers in gmat prep to this forum. Please help

\frac{concentrate}{juice}=\frac{1}{4}, as 1 part of concentrate is to be mixed with 3 parts of water to get 4 parts of juice;

200 6-ounce of orange juice = 100 12-ounce of orange juice;

As 1/4 th 100 12-ounce of orange juice must be concentrate --> 100*1/4=25 12-ounce of cans of concentrate are required.

According to the directions on a can of frozen orange juice concentrate, 1 can of concentrate is to be mixed with 3 cans of water to make orange juice. How many 12-ounce cans of the concentrate are required to prepare 200 6-ounce servings of orange juice? a)25 b)34 c)50 d)67 e)100

We need concentrate:water in 1:3 ratio.

We need to prepare 200 x 6-ounce servings or 1200 ounces Let there be x ounces of concentrate and hence 3x ounces of water

I'm surprised I got this right...here's how I approached this. X can concentrate : 3X can water is given as the ratio 200 cans of 6 oz each = 1200 oz total fluid.

x+3x = 1200 Therefore x=300 oz of orange juice concentrate Now we are asked how many 12 oz cans of concentrate are required. From 300, 12 goes 25 times so the answer is A

A. 25 B. 34 C. 50 D. 67 E. 100

concentrate : water = 1:3

To produce 200 6 ounce serving , we need 100 12 ounce cans.

Now , # of concentrate can in 100 = 1/4 * 100 = 25 _________________

Answer: A.

Hi Bunuel,

How do we know that the can is of 12-ounce? Because its given in the last sentence that how many 12-ounce cans are required. But its not given that the can of concentrate in the mixture: (1 can of concentrate + 3cans of water) is of 12-ounce.

Please clarify.

That's true. But what the first sentence is saying is that 1 part of concentrate is to be mixed with 3 parts (thrice of that of concentrate) of water to make an orange juice. So, whatever amount of concentrate you take, you'll have to mix it with 3 times as much water.

Does this make sense?

Yes Bunuel, even if we consider the can a concentrate of 4-ounce we will get the same answer.
