Hi, The cylinder's volume is pi*r^2*h. There are 3 ways to lay the crate: with the 8x10 side down, with the 8x12 side down or with the 10x12 side down. Whether the 8x10 side or the 8x12 side is down, the maximum radius would be 4 feet (diameter 8 feet), so the 8x12 would give a larger height and lar...

Hi, Focus on the interior angles of the triangle. Let's call them A (near x), B (near Y) and C (near Z). Notice that Angles x and A total 180 degrees because they form a line. Same with B and y. And same with C and z. Also, there are 180 degrees in the triangle. Knowing that x=y tells us that A=B. B...

Hi, Generally, no -- that amount of time does not matter. Your score is based on number of questions answered (answer them all!), number of correct answers, and difficulty level. The difficulty level of each question is pre-assigned by GMAC. That is, if you should receive a 37-level question based o...

Hi, A premise is a stated fact or principle that supports the conclusion. "Evidence" can be used in place of the word premise. All premises must be taken as true. The conclusion is what the author wants you to believe; it will likely be a recommendation to solve a problem, an interpretatio...

Hi, all, If this is an official GMAC question and they say the answer is (B), I stand corrected. Otherwise, the answer has to be (A). Here's tbe deal. "Inference" has a special meaning on the GMAT. It means something that must be true based on a series of facts. Inferences generally do not...

Hi, We are asked to weaken the conclusion that T disliked central governments for the specific reason that he blamed N for his childhood poverty. All answer choices are deemed true. Even if we take (A) as true -- that scholars NOW know that N was not to blame for poverty even though people then did ...

Hi, On bold-faceones, take the sentences one at a time, beginning with the easier one. In this case, the second sentence strikes me as easier. Because it offers a recommendation on the basis of facts in the argument, it is the conclusion. (Conclusions tend to be recommendations, interpretations of e...

Hi, You don't really have to do the math on this one, if you just think about it logically. Moving from left to right: 6/7 is a bit bigger than 5/6, so 6/7 - 5/6 will bring us to a small fraction greater than 0. 4/5 is a bit smaller than 5/6, so when we add 4/5 back in, we go above the 1/2 mark but ...

Hi, This question is not so bad if you convert the rates into whole numbers and then just test the answer choices. We are not told how big the job is, so you can make up a job that is a multiple of the two rates (18 and 36). So the job can be 36 units. Since R can complete the job in 36 hours, R's r...

Hi, Generally on the GMAT, "being" is wrong. But more importantly here, the subject is "group". Group is a collective noun and is singular even though it is composed of many things, here macaques. Thus, eliminate (A), (D) and (E) because they read group . . . are. For B and C, th...

For Data Sufficiency questions, first ask yourself what you need to know. Here, to find k, you need to know m - n (isolate k in the equation). Statement 1, viewed in isolation, gives you only n, not m, so it is not sufficient. Thus, the possible answers are B, C, and E. Statement 2, viewed in isolat...

Hello, The first step is to identify the conclusion (what the passage is trying to prove) and the premises (the reasons for the conclusion). All of the premises must be considered as true. There will be some logical flaw in the reasoning -- the hidden assumption. In a strengthen question, the answer...
