Gentlemen, thank you for your replies. Knowing the algorithm wouldn't affect how I prepare: I'm still going to try to correctly answer every question. I was more curious than anything else.

Answering 'X' questions incorrectly - does it matter which?

This has probably been asked, but I can't find it in the archives, so please bear with me if the answer is out there. Suppose that answer 6 questions incorrectly in the Quant section (I chose '6' arbitrarily), and that each of the 6 questions is considered to be in the 700-800 range. In terms of con...

Hello, For the following: What is the median of positive integers x, y, and z if their average is 120. (1) x = 100 (2) y = 120 OA: B 1) x = 100. In-suff. 2) y = 100. Now what if the order of the integers are y, x and z. In-this case 2 is in-sufficient. I am thinking that the question is implicitly ...

It could be 2, but that will also give you a remainder of 0.

10 + 2 = 12/3 = 4 R 0
Good point! I have a penchant for making observations which add no value. ;-)

If m and n are positive integers, is the remainder of (10^m + n)/3 larger than the remainder of (10^n + m)/3 ? 1. m > n 2. The remainder of n/3 is 2 When a POWER OF 10 is divided by 3, the remainder will always be 1. 10/3 = 3 R1. 100/3 = 33 R1. 1000/3 = 333 R1. From there, the remainders will proce...

I thank both of you for responding and for highlighting the mistake I made. I proceeded from a baseless assumption that 'S' and 'T' were integers. When I saw the values "-1/2" and "1/2" to show how the product could be negative, I emitted a silently potent "ohhhhhh".

Data Sufficiency question from Manhattan GMAT CAT

I purchased 6 CATs through the Manhattan GMAT website. This Data Sufficiency question comes from one such test. My answer conflicts with the answer provided by Manhattan GMAT and, after reviewing my logic multiple times, I'm still not able to see why my answer is incorrect. I won't post the answer g...

Algorithm for computing overall GMAT score

A few days ago, I purchased 6 CATs on the website for ManhattanGMAT. Upon finishing one of these CATs, I was presented with an overall score of 730. As much as I was encouraged by this result, I am also puzzled about how the result was computed. My breakdown was Q45/V45. The Quant was at the 68th pe...

Referring to choice (B), what if x=10 and y= -5? x/y would equal -2, which satisfies the inequality. If x > 2 and y < –2, then: A. x/y > 1 B. x/y < –1 C. x/y < 0 D. x + y > 0 E. xy > 0 When posting questions, please use the spoiler function to hide the correct answer. This will allow others to a...

I chose x=1 as the value used in testing Statement (1). The question becomes : Is 1-y+1 > 1+y-1?, or Is 2-y > y? If y=1, the two sides are equal If y>1, the answer is 'no' If y<1, the answer is 'yes' Statement (1) is insufficient To test Statement (2), I selected y= -1. The question becomes: Is x-(-...
