If, for each size, there are equal numbers of red and green toys in a certain production lot, what fraction of the total number of green toys is large?

(1) In the production lot, 400 of the small toys are green. (2) In the production lot, 2/3 of the toys produced are small. B Source: Official Guide 2020 Say the company produces x numbers of small and y numbers of large toys. Thus, Number of red toys = Number of green toys =x/2 + y/2 = (x + y)/2 We have to get the value of y / [(x + y)/2] = 2y / (x + y) = 2 / (x/y + 1) If we get the value of x/y, we get the answer. Let's take each statement one by one. (1) In the production lot, 400 of the small toys are green. => x/2 = 400 => x = 800. Can't get the value fo x/y. Insufficient. (2) In the production lot, 2/3 of the toys produced are small. => 2/3(x + y) = x 2x/3 + 2y/3 = x 2y/3 = x/3 x/y = 2. Sufficient. The correct answer: B Hope this helps! -Jay _________________ Manhattan Review GMAT Prep Locations: GRE Manhattan | ACT Tutoring San Antonio | GRE Prep Courses Boston | Houston IELTS Tutoring | and many more...

We're asked for the fraction of the total number of GREEN toys that are LARGE. This question can be approached with a mix of logic and TESTing VALUES. (1) In the production lot, 400 of the small toys are green. With the information in Fact 1, we know that there are 400 small RED toys (since there are EQUAL numbers of red and green toys in each size), but we don't know how many LARGE GREEN toys there are, so the answer to the question would change depending on number. Fact 1 is INSUFFICIENT (2) In the production lot, 2/3 of the toys produced are small. With Fact 2, we know that 2/3 of the toys are SMALL, so the remaining 1/3 of the toys are LARGE. The prompt tells us that there are EQUAL numbers of red and green toys in each size). These ratios are enough to answer the question; you can prove it with Algebra or by TESTing VALUES. IF.... TOTAL toys = 6 Total Small = 4 (2 red and 2 green) Total Large = 2 (1 red and 1 green) Total fraction of GREEN toys that are LARGE = 1/3 IF.... TOTAL toys = 12 Total Small = 8 (4 red and 4 green) Total Large = 4 (2 red and 2 green) Total fraction of GREEN toys that are LARGE = 2/6 = 1/3 Etc. The answer will ALWAYS be 1/3. Fact 2 is SUFFICIENT Final Answer: B GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com • 5 Day FREE Trial Study Smarter, Not Harder Available with Beat the GMAT members only code • Free Trial & Practice Exam BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Award-winning private GMAT tutoring Register now and save up to$200
