Re: Is x=1 data sufficiency Q

Hi samcr22: Let's break this problem down: 1) Our question is "is x=1"? So this is a yes/no question. 2) Start with statement #2 because it is easier. Statement #2 tells us that x is NOT equal to 2. Does it answer the question whether x=1? No, it doesn't. x could be 1, or it could be anoth...

Re: Square root (negative or positive)

I always viewed it as being an unknown vs. a known. When you take the square root of something then you are told the number that you are operating on. Say √4 is definitely 4 which has the root of 2. On the other hand, x^2 = 4 can mean 2 or -2 for x because the x part is unknown and could be eithe...

Re: If x and y are non-zero integers

Hi Hima, Take a look at the first expression, statement 1. You have -4x - 12y = 0. If I add 12y to both sides, I get -4x = 12y. If I divide both sides by -4, I get x=-3y. If x = -3y, then we have the following two scenarios. Either: a) x is positive and y is negative OR b) x is negative and y is pos...

Re: At a certain store, each notepad costs x dollars and each

alok2, I don't think that you can quite make that jump to have x <= 0 because then your 'y' term goes away instead of becoming a '- y'. alok2, gregoryssmith is right--you have completely eliminated y in your result, but if you subtract one from the other you will still have -y. Ron's method is t...

Re: x = 8y + 12

If x and y are integers such that x= 8y + 12 what is a common divisor for x and y? a. x = 12u b. y = 12z where u and z are also integers. thx in advance P PoonamchiK, This problem looks a little weird to me. Will you check the specific wording and confirm that all I need to do is find a common divi...

adityaj123 Wrote:Does the questions with answer NO come in real GMAT exam??


adityaj123, definitely! Based on the information in a statement, you absolutely can get an answer of NO for the question, and NO would be sufficient. Yes, we have seen many such instances of that on the real GMAT.

Re: Each of the following equations has at least one solution

Kiran, This is a tough question, which is why it is a 700-800 level question. You have to focus on a few important aspects: 1) pay attention to parentheses, as Ben demonstrated above. 2) make sure you know how to deal with a negative power--for example, know that 5^-2 = 1/25. If you have a negative ...

Re: a pronoun in a parallel structure, ambiguous or not?

Hi rx_11, This is a good question about a difficult issue. As the book states, the issues of repeats, promixity, and case are NOT absolutes, but can help you figure out whether the pronoun is being used properly. In the sentence you cite, notice that there are two clauses: 1) Although the company ha...

Re: MGMAT CR Ed 4 - Chap.5 Problem#6: Network Television

Good work everyone. My favorite approach to this type of question is to knock out the obvious wrong answers first, then use logic and number substitution to confirm my answer.

Remember, on the GMAT verbal four wrongs make a right! Thus, a POE approach is generally very helpful.

Re: Should the Present Perfect Tense always be used with "After"

Hi rx_11 and imran, I think the use of "have been trimmed" rather than simple past tense "were trimmed" is to indicate that not only were the horns trimmed in the past but the animal tenders will also continue to trim the horns in the present to keep the horns short. Otherwise, a...
