A company produces a certain toy in only 2 sizes, small or large, and in only 2 colors, red or green. 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. DS61602.01 OG2020 NEW QUESTION

The Logical approach to this question will focus on the fact that we are asked to find the ratio, so we don't necessarily need exact numbers. Statement (1) doesn't give us any information regarding the ratio between the groups of small vs. large toys, and is thus insufficient. Statement (2) tells us that 2/3 are small, meaning 1/3 are large, and since the number of red and green toys is equal for each size group, then 1/3 of the green toys are large and the other 2/3 are small (as they make half of these groups). The correct answer is (B). Posted from my mobile device

(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.
DS61602.01 OG2020 NEW QUESTION For the red category, let \(s\) and \(l\) be the numbers of small and large toys produced, respectively. For the green category, the production volumes are the same as those for the red category according to the original information. Globally, \(2s\) and \(2l\) are the numbers of small and large toys produced, respectively. The original question: For the green category, \(\frac{l}{s+l}=?\) 1) We know that \(s=400\), but no information is given about \(l\). Thus, we can't get a unique value to answer the original question. \(\implies\) Insufficient2) We know that \(\frac{2s}{2s+2l}=\frac{s}{s+l}=\frac{2}{3}\) \(1\frac{s}{s+l}=1\frac{2}{3}\) \(\frac{l}{s+l}=\frac{1}{3}\) Thus, the answer to the original question is a unique value. \(\implies\) SufficientAnswer: B

DS61602.01 OG2020 NEW QUESTION We are given that the number of green large = red large and green small = red small. We need to determine the value of (large green)/(total green). Statement One Alone: In the production lot, 400 of the small toys are green. Only knowing that we have 400 green small toys is not enough information to determine large green/green. Statement one alone is not sufficient to answer the question. Statement Two Alone: In the production lot, 2/3 of the toys produced are small. Since 2/3 of the total are small, 1/3 are large. Thus, (2/3)/2 = 1/3 are small green and (1/3)/2 = 1/6 are large green. Thus, the large green toys are (1/6)/(1/3 + 1/6) = 1/(2 + 1) = 1/3 of the total number of green toys. Answer: B

Hi ScottTargetTestPrepI did not understand this sentence "Thus, (2/3)/2 = 1/3 are small green and (1/3)/2 = 1/6 are large green. Thus, the large green toys are (1/6)/(1/3 + 1/6) = 1/(2 + 1) = 1/3 of the total number of green toys" Could you kindly elaborate here more please?

Hi All, We're told that a company produces a certain toy in only 2 sizes, small or large, and in only 2 colors, red or green  and that for each size, there are EQUAL numbers of red and green toys in a certain production lot. 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: GMAT assassins aren't born, they're made, Rich

Since 2/3 of the toys are small, (2/3)/2 = 1/3 of all toys are small green toys. Similarly, since 1/3 of the toys are lare, (1/3)/2 = 1/6 of all toys are large green toys. The question asks what fraction of green toys are large. So we have 1/6 of the toys are large green and (1/3 + 1/6) of the toys are green, so the fraction is (1/6)/(1/3 + 1/6) = 1/(2 + 1) = 1/3.
