We can calculate the values for m, f and a from the table given:

m=75, f=78 and a= 513/7 < 75

therefore (A) a<m<f.

In fact, it does not even make sense with x=0. In that case y=0 and all answer choices are correct. Probably it was x !=0 (not equal)?

From the question we can conclude that the remainder must be at least 1. Statement (1) tells us that (p-m)/2 > 1, so the remainder of p/m must be greater than 1. SUFFICIENT Statement (2) tells us the least common multiple of m and p is 30. So let's break it down into prime factors: 30 = 2*3*5 This l...

I would go with E. (1) if a quadrilateral is devided into two triangles of equal area, its not necessarily a parallelogram. The figure could be a kite as well. INSUFFICIENT (2) if two adjecent sides are equal, we don't know anything about the two other sides, i.e. we don't know whether they are para...

Re: Kaplan GMAT 800 DS solution wrong

However statement 1 could be true and cubed term could still be negative eg. a=-2, b=-3. So I believe the correct answer is (E)! No, if a>b then a-b must be positive, since if both are positive the smaller number is subtracted from the bigger number, if a is positive and b is negative, a negative n...

The median is the number that stands in the middle, if you order the number from lowest to greatest. If there are two numbers in the middle, its their average. For the problem above lets assume you have 100 projects. Then you get number of projects number of employees 25 >=4 40 3 35 <=2 So, from the...

From the question we can derive the equation: p-s-pt/100=?

statement (1) tells us that p-s=244 and so 244-pt/100. NOT SUFFICIENT

statement (2) tells us that pt=7552 and so p-s-7552/100. NOT SUFFICIENT

However both statements combined give us 244-7552/100. SUFFICIENT

So the answer is C.

Probably you understand it better that way: We are searching for numbers 1, 2, 3, ...., n such that 1*2*3*.....*n = m*990 Don't bother with the m on the right side, it's just for illustration that the product should be a multiple of 990. We are actually looking for the numbers on the left side. We a...

Are you sure this is not a printing error?
The only thing I can infer from the question is that the remainder has to be a multiple of 3, but that does not answer the question.

Re: lawyers

10+11+13-2n=28 ----〉why 2n and not only n?? Because n=number of lawyers belonging to all three firms at the same time 10-n=lawyers only in X 11-n=lawyers only in Y 13-n=lawyers only in Z Therefore the total number of lawyers is (10-n)+(11-n)+(13-n)+n = 10+11+13 -3n+n = 10+11+13 -2n =28

Re: Are Idioms Bad?

Can someone elaborate why idioms are important to learn? I can tell you from my experience that idioms are extremely important. My verbal score was very bad due to SC (v25). I just scanned over the main concepts in my preparation most of which I remembered from my English classes in high school. I ...

Re: inequalities

I would first consider the different cases for a and b: 1. a>0, b>0 2. a<0, b<0 3. a<0, b>0 4. a>0, b<0 Statement (1) tells us a<b, therefore it can only be case 1., 2. or 3. In all cases a-b<0 and b-a>0, and consequently 1/(a-b)<b-a. SUFFICIENT Statement (2) tells us 1<|a-b|, so there are two cases...

Need help on preparation for retaking

Hi guys, I took my GMAT today and scored disappointing 600 Q48 V25. After I had read some of the threads in this forum I wondered how ridiculous my preparation for the test had been. I have only studied one week entirely following the concepts of princeton review. Now I'm confident that I can improv...
