Yeah, I got D. Statement 1 rules out the only even prime number (2) and guarantees that x will be an odd number. Odd - Odd = Even. Y can be any prime ( 2 or 3,5,7 (odd)) and the product will be even. Statement 2 states Y is 2. Any multiple of 2 is even. D is the answer.

Another thing, since we're squaring, the sign doesn't matter. The values of n are 2,1,0,-1,and -2. Either way, we can't come up with the minimum value of m.

Hi, just found this post while searching for inequality problems. for n^2-m^2 to have maximum value, we need two things. The maximum value of n and the minimum value of m. From the given inequalities, the maximum value of n is 5, and the maximum value of m is 2 (we also know that m <= n, so the mini...

Nevermind. Didn't see Brian's post before. But the restriction of x+y!=0 is brilliant!

How about x+y != 0? I don't know if any factorial can be equal to 0 unless its 0! and I'm not sure if 0! exists (I'm not a mathematician). In any case, if 0! does exist, then x+y must equal to 0. x+y=0 only tells us x and y are on the opposite side of the number line, insufficient to answer the val...

E all the way. Statement 1. Factor everything out, you will end up with 2(x-y)=2(x-y). Insufficient. Statement 2. 3x+2y=24. Since 3 (from x) and 2 (from y) are both factors/divisors of 24, you need another equation to solve for x and y. Insufficient. Statement 1 and 2 leaves us with no concrete conc...

The question, I think, may be in the low 600 range question. Just need a little knowledge in number theory. Statement 1 is not sufficient because J is still unknown. Statement 2 allows us to come to a conclusion that the numerator will be a multiple of 9. K is positive integer, thus K must be greate...

This sentence contains two past events. You need a past perfect modifier to distinguish which event occurred first. So B is the right answer. BTW, I'm listening to Little Wing.

If you look at the verbs used in D, "these _____ are resulting" - is a awkward and wordy. In C, it boils down to "the result ___ is". Concise and simple.

If you are confused, first try POE strategy. A and B are wrong; "the result" is a singular noun. E is a fragmented/run-off sentence. Now, you are down to C and D. abhishek.pati's analysis of D is correct. D is too wordy and and awkward. C, on the other hand, is very clear. Choose C.

A is definitely wrong because the the intro sentence, "After its international debut" does not modify "the progress". The rule with modifying phrase/clause is that the modifying phrase/clause must modify a noun immediately after the comma. A "progress" cannot have a deb...

Except that y can be 1,-1 nice one phanideepak, forgot about the -1. Yes I didn't bother to expand it. Just seeing the two prompts, I knew than the only possibil...

1) x and y are either 1 or 0 (only two integers that satisfy the equation)

2) x or y is 0

1 and 2) x and y are 0

Is my reasoning correct?

A quicker way to solve this problem?

This one is from Kaplan CAT (I find it increasingly that most math questions from Kaplan take more than 2 minutes to solve!)

if x + y^2 = ( x + y^2)^2 , what is the value of y?

1. x=y^2
2. xy^2=0 (only y is squared, not xy)

OA c
