Also, any two perpendicular lines will have the product of their slopes as -1. So you can also take the question as asking 'is the product of their slopes -1 ?' Now, we can find out the slope of a line if we know two points it passes through. The question itself gives us one point for each line. Sta...

Line K passes through point (1,1) and M passes through (1,-1). Draw those two points and you will realise that one is in 1st quadrant and other in 4th. This is what the question stem tells you. And the question is are the two lines perpendicular. Statement 1: Tells us that lines intersect at point 1...

Great story woojet! a BIG congratulations! You removed the 'un' from 'unremarkable'. Reminds me of that scene from Pursuit of Happyness where Will Smith says to his son - "Don't ever let someone tell you, you can't do something. Not even me. You got a dream, you got to protect it. People can’...

I know you addressed the question to Brent - but would just like to tell you that I have come across questions like these (votes and candidates) in the past and what the test makers are almost always testing here is if the person falls for the trap - which is assuming that there are only 2 candidate...

This involves conditional probability. The probability of A conditioned on B, denoted P(A|B), is equal to P(AB)/P(B). The division provides that the probabilities of all outcomes within B will sum to 1. Conditioning restricts the sample space to those outcomes which are in the set being conditioned ...

Thank you.
Yes, the question did come with an explanation which more or less matched with your previous explanation. Is there a way you know I can let Princeton know about this so that this can be rectified in the future editions of the book? Thank you.

Thanks a lot! Really appreciate your detailed explanation. However, if you consider √2 and -√2 to be X and Y respectively, both statement 1) and statement 2) are satisfied [√2*(-√2) = -2 which is an integer and √2 + (-√2) = 0 which is also an integer]. And of course, √2 and -√2 are n...

Krishp84 (and JennySpalek this should help you as well), I guess you calculated the LCM for both numerators and denominators. The HCF of 3 and 10 (the highest number common in them) is 1 [3=1*3 and 10=1*2*5]. So the answer to the question JennySpalek asked should infact be 4/1 or just 4 (and not 4/3...

Princeton Review - Wrong answer and explanation?
Hi everyone, I encountered the question below in Drill 11 of the Quant section of 'Cracking the New GMAT 2013' by Princeton Review. Are X and Y integers? (1) the product XY is an integer (2) X + Y is an integer The book states 'C' as the answer - I think the answer could be E. Can someone who has lo...

Hi nk_81, The answer would have been B had the question stem asked "The answer to which of the following questions would be most relevant to evaluating the conclusion?" That is, if were supposed to find out if the octane levels are really less, then we would have asked "ok, if its rea...

Hi Gaap, You didn't state exactly when you're taking the GMAT. If you have sufficient time, I suggest taking a mock to see where you are placed. You might already be at a 540. Plus, with a bit of brushing up of concepts and grammar, you might get there. If after that, you think you still need to joi...

Thanks a lot Ravish & Rezinka. 1. Thanks, the use of whether for 2 or more alternatives is what I didnt know. Would have gone with the correct ans otherwise. 2. Thanks Ravish for the explanation. But my question of 'like' vs 'as' remains unanswered. In general, what Ive been noticing is that, as...
