Congrats on the amazing score! I'm really glad that you posted this--I've been struggling with whether or not to retake, and I've finally decided that I will. I took the GMAT two weeks ago and got 720(47Q, 42V) and was crushed. I scored 750-760 on the last three practice tests I took leading up to t...

I don't think (2) is sufficient. I would go with A. The second statement says that the area is 20, which means that 20=.5*base*height, so 40=base*height. If you consider a case where one side is the base and the other is the height, we could have a base and height of 10 and 4 or of 8 and 5. If 10 an...

I am confused why the correct answer is not C. If we know there are 30 days in March, from A the lion never roared on a rainy day, and B the lion roared on 10 fewer days than it rained, then wouldnt the only possibility be roared 10/30 and rained 20/30? There are 31 days in March, but the split cou...

In the first problem, you need to account for the fact that 2 and 5 could show up in two different ways, doesn't matter which die each shows up on we just need both numbers. We ARE multiplying to get 1/18, we just need to add to get there (1/6*1/6 + 1/6*1/6) since these are two distinct probabilitie...

I need to understand the necessity of the word 'would' in the OA. Can someone please explain this? Without 'would', the sentence implies that the microbe would only kill humans who have no natural defense against it. We want to look for a meaning that implies that ALL humans are at risk, because no...

cbaum, your approach of using the radius to get the side is right.Although, you do not get a 1-1-2^1/2 here as its NOT a 45-45-90 triangle. Instead if u split that isos triangle into 2 triangles by dropping a perpendicular, u get a 30-60-90 i.e. 1-3^(1/2)-3 triangle. From this we get that (side of ...

The way I would have done it is create an isosceles triangle within the equilateral triangle using the radius (the sides of this new triangle will go from the center of the circle to two different points of the equilateral triangle). Then I would have used the isosceles relationship 1:1:2^(1/2) to d...

We are left with 6, and these represent people who have been counted 3 times - once for each group. We want to leave one instant of these employees, so these 6 employees represent two instances of 3 employees that work in all 3 restaurants. Hi, could someone please explain why/how we get from 6 to ...

The probability of selecting X on the Nth pick is equal to the probability of selecting X on the FIRST pick. Sorry, maybe I'm misunderstanding, but doesn't this imply replacement? And in the problem, it notes that Renee is picking her candy AFTER Jack has already chosen (I assume that he will not b...
