Also awa is back

What was the point of changing the entire exam

Is it compulsory to give AWA? How does it work?

Not as a part of the test, but as a stand alone "package" for another USD 30! Not sure how many universities will make it mandatory. As of now, only HBS has confirmed.

It is now called "GMAC™ Business Writing Assessment"

Agree, a pretty shortsighted move.

I just appears to be lengthy, but can be done in 2 minutes. I intentionally wrote it this way so that the person who asked the question could understand the steps. Irrational denominator either cross multiplies or rationalises, but eventually terms cancel each other in almost all GMAT questions of this type.

hi, could someone please help me with the working for this one?

Check here: if-x-10-x-1-2-10-1-2-what-is-the-value-of-x-421862.html

please help on this a-set-consists-of-three-positive-integers-that-are-not-coprime-to-each-418811.html#p3428377

the question does states that 3 integers are non-coprime and the answer considers product of 2,3,5. but 2,3,4 are coprime . Need calrity

Did you find the solution ?

Are GMAT Prep questions for Quant, Verbal and DI totally different from GMAT Prep (focus)? I want to solve them but don’t want to touch the question bank for official mocks.

How many months preparation is enough for an average student?

If targetting for 720+

I didn’t find the best explanation for this question on forum.... please help me here............Lily has only red and blue balls in a jar. If she removes three balls, is the probability of getting all red balls greater than the probability of getting at least one blue ball?

(1) The number of red balls is more than three times the number of blue balls.
(2) Less than (1)/(4) th of the balls in the jar are blue.

For both these cases, or even if we combine the cases, if the total number of balls is high - The statements are sufficient.....but if the total number of balls is very low (minimum 5), the probability of getting atleast 1 blue surpasses the probability of getting all reds. You can try two cases. : 1) Total 1000 balls (choose R > 3B and B < R/4) (2) Total 5 balls (R = 4, B = 1).......You see, both these cases adhere to Statements 1 and 2 but neither can confirm nor deny. E is the answer

2,3, and 4 are NOT co-prime. Actually, the answer is not 2,3,5 and their LCM. The answer would be 6,10,15 and their LCM, which happens to be 30.....We are said that the numbers are not co-prime, i.e., there is atleast 1 common factor other than 1. (So, 1-2-3 are ruled out, 2-3-4 is the next sequence). We are also said that the numbers are not multiples of each other, which means, 2-3-4 is also ruled out and 2-3-5 is the next sequence in the list (we are trying to keep numbers minimum so that LCM is also low, which the question needs)......But 2-3-5 are co-prime, so we will need to alter them to make them "not co-prime" with one another and also "not a multiple of one another", while keeping them as low as possible.......So what we do is (2*3), (3*5) and (5*2). No two numbers are co-prime. No numbers are multiples of each other. Numbers are 6,15, and 10 and LCM is 30.

Also, as I had earlier mentioned, 2-3-4 were already ruled out as they were not co-prime. So checking multiplicity should start with 2-3-5.

guys.. you have any idea about this?
