The ratio C to W is 1 to 3 in the prepared orange juice. Hence, if x number of 12-ounce cans of C are required to prepare 200 6 ounce serving of orange juice, then the total orange juice made will be 200 times 6 or 1200 ounce. In those 1200 ounces, 1part is C, and 3 parts W. Means 300 ounces of C and 900 ounces of W.
Now ask over how many 12 ounce cans of orange concentrate are required. Just divide 300 by 12 to answer [spoiler]25.

Hi Sbhawal,
What given in the question is,
1 can of Orange Concentrate + 3 can of water = 4 can of orange Juice
What we asked to find is,
for 1200 ounce of orange juice how many 12 ounce of orange concentrate are required.
Multiply first equation by 300
300 can of orange concentrate + 900 can of water = 1200 can of orange juice
300/12 = 25
Hence answer is A

Total = 200 6-ounce servings = 200*6 = 1200 ounces.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 prepate 200 6-ounce servings of orange juice?
A) 25
B) 34
C) 50
D) 67
E) 100
Since each can = 12 ounces, the total = 1200/12 = 100 cans.
In these 100 cans of mixture, since concentrate:water = 1:3 and 1+3=4, concentrate/total = 1/4.
Thus, in the 100 cans of mixture, the number of cans of concentrate = (1/4)100 = 25.
The correct answer is A.

Here's a slightly different approach that uses equivalent ratios.sbhawal wrote: If 1 can of orange concentrate requires 3 can of water to make orange juice. How many 12 ounce cans of orange concentrate are required to prepare 200 6 ounce serving of orange juice?
A. 25
B. 34
C. 50
D. 67
E. 100
The first part tells that, for every 1 can of concentrate, we can make 4 cans of juice.
Let's be even more generic, for 1 volume of concentrate, we can make 4 volumes of juice.
Okay, now notice that we have a problem with the volume mismatch in the question. It involves 12-ounce cans of concentrate and 6-ounce servings.
So, let's reword the question. Instead of making 200 6-ounce servings of juice, let's make 100 12-ounce servings of juice. This is acceptable since we're still making the same amount of juice!
We're now asking, "How many 12-ounce cans of the concentrate are required to prepare 100 12-ounce serving of orange juice?
We'll solve this question using equivalent ratios.
(volume of concentrate)/(volume of juice): 1/4 = x/100
Solve for x to get [spoiler]x = 25[/spoiler]
So, the answer is A
Cheers,
Brent

Using ratios:
Orange:Water:Total
1:3:4
x 50 becomes
50:150:200 (6 oz servings)
25:75:60 (12oz servings)
So answer = 25
Orange:Water:Total
1:3:4
x 50 becomes
50:150:200 (6 oz servings)
25:75:60 (12oz servings)
So answer = 25
Thanks Brent!!
Your explanation worked the best for me.
