Hi Brent, If the president had to be selected first, this would be different right? Would it then be 17/80? Thanks! I'm not sure what you're asking. The president IS selected first. That said, the answer will always be 1/5, regardless of the order in which the three positions are filled. Cheers, Br...

I might be missing something here, but what leads us to assume that the triangle is isosceles?Is that just a function of the parallelogram? Thanks! The figure indicates that ∠NMR = x and that ∠NRM = x. Since ∆MNR has two equal angles, it is isosceles. Wow! I totally missed that, didn't even s...

Since ∆MNR is isosceles, MNOP is a trapezoid, and NOPR is a parallelogram, the following figure...

Hi toby001, The GMAT will sometimes test you on concepts that you know, but in a way that you're not used to thinking about. For example, you can probably FOIL this calculation rather easily: (X+1)(X-2). You know the 'steps' and should be able to write everything out. In that same way, you should b...

If 2 < x < 4, what is the median of the numbers 0, 5, x, 1, 7, and 3? (1) 2x - 5 = 0 (2) 2x^2 - 7x + 5 = 0 Statement 1: 2x-5 = 0 Here, we can solve for x. Since all 6 numbers are known, the median can be determined. SUFFICIENT. Statement 2: 2x² - 7x + 5 = 0 Since the two statements cannot contradi...

Thanks mba2017dallas! I honestly didn't study too much for verbal. Focused most of my studying on quant. I did take a brief look at the MGMAT SC, and that was it. I plan to take it again though, and I'll probably do more of the MGMAT SC, CR PowerScore bible, and the OG and verbal review questions. d...

Thanks Matt. This is exactly how I arrived at my answer. How do we get from this point to the final answer? Thanks! Here's a cutesy way to guess the answer very quickly. The high-speed train's rate = z/x The low-speed train's rate = z/y So the high-speed train travels (z/x) - (z/y), or z*(y - x) / x...

Hi Dana, Thanks for your explanation! I initially chose B, and even after your explanation, I think B has to be an assumption. The argument says that because when X happened in the past, Y happened, that we can expect Y to happen again because X is about to happen. As B states, if X wasn't really th...

I think this is perhaps one of those cases where "most" in the question stem implies that there's not a perfect answer choice, but that one does the job much better than the rest. The introduction of new drugs into the market is frequently prevented by a shortage of human subjects for the clinical t...
