Re: If p is the perimeter of rectangle Q...

Hi All, The question asks us to figure out the PERIMETER of rectangle Q. For that, we'll need the length (L) and width (W) of the rectangle. 1) Each diagonal of rectangle Q has length 10. From this Fact, we can create one equation: L^2 + W^2 = 10^2 Unfortunately, there are lots of different values f...

Re: Can you help with this problem? Thanks!

Hi All, We’re told that S and T are both POSITIVE INTEGERS and that S/T = 64.12; we’re asked which of the 5 answers COULD be the remainder when S is divided by T. The wording of the question implies that there is more than one possible answer, so the first example that we come up with might not be l...

Re: D10 OG 12 Page 21 Geometry

Hi All, To start, it’s incredibly rare to see a Quant question on the GMAT with so many inter-connected shapes (including a hexagon!), so you shouldn’t worry about this question if you got it wrong the first time you attempted it. You can solve it with a mix of Geometry rules and TESTing VALUES. Wit...

Re: k = 2^n + 7, where n is an integer greater than 1. If k is divisible by 9,

Hi All, We're told that K = (2^N) + 7, where N is an integer greater than 1 AND K is divisible by 9. We're asked which of the following MUST be divisible by 9? This is a great 'concept question', meaning that you don't actually have to do much math to answer this question if you recognize the concep...

X = 2, then the answer become.... (A) 3x + 2 = 3(2) + 2 = 6+2 = 8 NOT Odd (B) 7x = 7(2) = 14 NOT Odd (C) 8x +5 = 8(2) + 5 = ...


Re: Working alone, Printers X, Y, and Z can do a certain printing job,

The math behind this question can be approached in a number of different ways, including as a rate or as a ratio. At a rate of 200...


Re: Job Scope after Master in Corporate Finance from Henley Business School

Hi Akshat2000, You're asking a rather specific question, so you're not likely to randomly come across someone who can answer it. That having been said, many Schools keep in touch with their Alums (to learn more about how those people used their degrees, where they currently work, their annual pay, e...


Re: MATH

Hi namokshi, From your post, I'm going to assume that the equation that you included is meant to be: Z = 1 + (1/X) and X > 1 As X increases, the value of (1/X) decreases - so we'll be adding a potentially small fraction to 1. We can actually TEST THE ANSWERS here - and use the answer choices to our ...
