GMAT Strategy

I agree, this question is hard... from the moment you look at it you are like "whoa!" whereas the GMAT questions I fear the most are the tricky ones that seem deceptively easy and lead you into trap answers... those are the worst coz you don't even know you are wrong...

I think #26 statement 1 should read:


n is not divisible by 2


37 should be:

In the sequence of positive numbers x1, x2, x3, what is the value of x1

Yes the tricky ones that trap me are usually DS questions where I fail to consider that one odd possibility that kills the problem. In case of PS I usually fall for those questions which ask you to find something based on certain conditions. You see that problem, you get excited and you solve it and chose the answer which turns out to be different than what the questions intends to ask.
Eg: P takes 8 hours and Q takes 16 hours to finish something if they work individually. Lets say P works for 2 hours and then both of them work for two more hours and Q takes over. How long did Q work?

Now, in this question, should we also include the time Q worked with P? Its so ambiguous because it does not ask how long did Q work alone. Such questions destroy my spirit when I get them wrong.

I think you hve to include when they worked together. So After 2hs P working alone he completes 1/4 of the job. Then they work together for 2 hrs and they complete 6/16 of the job = there is 6/16 of the job left for Q alone which he needs 6 hrs to complete. So Q worked 2 + 6 = 8 hrs... what do you thnk?

Could someone help me with #26, 27 and 28 didn't get them correctly and Ican't get them correctly

Folks, Could you please help me with the following question:

I am finding the answer as B and in the doc, its answer is shown as D.

Also, not able to understand what the following question is asking....

2) Each employee of company Z is employed in either Division X or Division Y, but not both. If each division has some part time employees, is the ratio of the number of full-time employees to number of part-time employees greater for Division X than for Company Z? D
a. Ratio of number of full time employees to part-time employees is less for division Y than for company Z
