Concentrate (C) Water (W) 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 25.

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 Regards, Uva. _________________ Known is a drop Unknown is an Ocean ### GMAT/MBA Expert GMAT Instructor Joined 25 May 2010 Posted: 15385 messages Followed by: 1872 members Upvotes: 13060 GMAT Score: 790 Quote: 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 Total = 200 6-ounce servings = 200*6 = 1200 ounces. 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. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

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 Here's a slightly different approach that uses equivalent ratios. 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 x = 25 So, the answer is A Cheers, Brent _________________ Brent Hanneson â€“ Creator of GMATPrepNow.com Use my video course along with Sign up for free Question of the Day emails And check out all of these free resources GMAT Prep Now's comprehensive video course can be used in conjunction with Beat The GMATâ€™s FREE 60-Day Study Guide and reach your target score in 2 months!
