Great discussion, thanks guys. It is a little frustrating that the GMAT tries to trap you in these specific technicalities!

Great thanks, I saw a question on another test which asks whether two lines "touch". I said no as I didn't think a line could touch itself but apparently the OA did. Thanks for clarifying any way. Some GMAT questions are pretty badly written in my opinion.

What if the two lines are exactly the same? Does that meet the definition of "cross"? Because if so, then shouldn't the answer be E eg. lines are different but parallel (do not cross), or lines are exactly the same (they cross).

Cichinel, When you write: GMATPrep3: 750 Q50 V41 9/37 4/16 2/11 2/14 (A day before the test) What does the 9/37, 4/16, 2/11 and 2/14 mean? Are those the number of incorrect answers?

BTW, your answers are correct. Additionallgy, for Q1 when I calculate 30! in Excel I get 265,252,859,812,191 x 10^18. Can't d=18?

Thanks eltonr. For Q1, can I ask how you know that d can be a factor of 1,2,3,...7? For Q2, how do you not know that there is no other solution which yields 130 cents (apart from trial and error)? I know that I have to pick two numbers (call them m and n) such that 1m + 3n = 10, but running through all the possibilities took me some time, and I was wondering if there was a quicker way to do it?

1. d is a positive integer. f is the product of the first 30 positive integers. What is d? (A) 10^d is a factor of f (B) d > 6 2. Marla buys two types of pencils only, which costs 21 cents or 23 cents. How many 23 cent pencils did she buy? (A) She bought 6 pencils in total (B) The total cost of her purchase was 130 cents Please show your reasoning, as I do not know how to do these (within the time limit anyways). Thanks in advance.

Hi guys, Happy New Year. The OA are D,A,B,B.

Guys, some practice questions. Please show your reasoning. Advocates insist that health savings accounts are an efficient method to reduce medical expenses. However, widespread adoption of these accounts will soon undermine the public’s health. One reason for this is that most people will be reluctant to deplete their accounts to pay for regular preventive examinations, so that in many cases a serious illness will go undetected until it is far advanced. Another reason is that poor people, who will not be able to afford health savings accounts, will no longer receive vaccinations against infectious diseases. The statements above, if true, most support which of the following? Wealthy individuals will not be affected negatively by health savings accounts. Private health insurance will no longer be available. Most diseases are detected during regular preventive examinations. Some people without health savings accounts are likely to contract infectious diseases. The causal relationship between an individual’s health and that person’s medical care has been adequately documented. Two years ago, the cost of the raw material used in a particular product doubled after an earthquake disrupted production in the region where the material is mined. Since that time, the company that makes the product has seen its profit margins decline steadily. Aiming to improve profit margins, the company's head of engineering has decided that he must find a new source for the raw material. Which of the following, if true, would cast the most doubt on the validity of the head of engineering's decision? New competitors have entered the market every six months for the past two years, resulting in price wars that have progressively driven down revenues across the market. Although the earthquake occurred two years ago, the region's mines have still not recovered to pre-earthquake production capacity. There are several other regions in the world where the raw material is mined, but those regions do not produce as much of the raw material as the current source region. The company could use a completely different raw material to make its product. Recent advances in mining technology will make mining the raw material much more efficient and cost-effective in the future. Analyst: Creative professionals, such as clothing designers, graphic designers, and decorators, often have very poor managerial skills and do not succeed when they try to run their own businesses. In fact, most of these creative types are less skilled in business than is the average white-collar professional who does not work in a creative field. Generally, creative talent and business acumen rarely go hand in hand. If the analyst's argument is taken as true, which of the following statements can properly be concluded? · No successful businesspeople are creative. · Some creative types are not less skilled at business than is the average white-collar worker who is not creative. · Creativity precludes success in business. · Any white-collar worker who is not creative is more successful in business than any creative professional. · Business is not a creative endeavor. Since the new publisher took control, a news magazine’s covers have featured only models and movie stars. Previously, the covers had displayed only politicians, soldiers, and business leaders. A leading gossip columnist claimed that the changes made the magazine relevant again. However, many newspaper editorials disagreed and suggested that the new publisher is more interested in boosting sales than in reporting important news events. Which of the following is an assumption necessary for the argument made by the gossip columnist’s opponents? · The charitable activities of models and movie stars often focus public attention on pressing problems. · Final authority for choosing the cover subject of the magazine lies with the publisher. · A magazine can boost sales while highlighting the coverage of important world leaders. · Some of the movie stars featured are now running for political office. · Magazine issues with models or movie stars on the covers are purchased at a rate more than three times greater than is the case with issues featuring politicians on the covers.

Guys, I am blind, I just realized I mis-read 1. The way I did it was to break up 450 into its prime factors and find out that y is a factor of 2^2 x 3 x 5. As for 2 however, the I basically sketched the graph y=-x, 3y=x, 4y=x and then shaded in the correct area. Works OK for two variables, but I have seen these types of questions with three variables (a third inequality is sometimes as part of statement 1 or 2). How would I do these questions quickly in this case? Or, rather than sketching the graph, is there a faster technique to do this in general?

1. If n and y are positive integers, and 450y=n^3, which is the following must be an integer? (i) y / (3 x 2^2 x 5) (ii) y / (3^2 x 2 x 5) (iii) y / (3 x 2 x 5^2) 2. Is m+z > 0? (i) m-3z > 0 (ii) 4z-m > 0

Comment III is not very well written IMHO (eg. who does "them" refer to?). I find it ironic that the critical reasoning questions seem to violate the grammar rules so thoroughly tested in SC.
