Thanks pete. So if on the GMAT we reach an answer x^2=16, can we conclude then that x=4, and thus this would be enough to make a statement sufficient? Alternatively if we reach an answer x^2=y^2, then can we also conclude that x=y, or in this case since we are dealing with variables then we cannot c...

Thanks pete, that does make sense. Now just a follow-up. Two points of confusion -If i wanted to do this the simple probability way, would i need to work out P(Josh & Jose) OR (+) P (Jose & Josh) = 1/6*1/5 + 1/6*1/5 ? - Secondly, say the question had said 3 are to be chosen from 6. Then the ...

Thanks Vivian, I'm certainly guilty of over analyzing gmat questions, but the reason is that i've messed up more than my fair share of questions where I think something is sufficient by looking at the data, but it really isn't because x is a quadratic and thus has two solutions (such as the way I di...

If 2x (5n) = t, what is t
I had a question hopefully someone can help me with. if 2x (5n) = t, what is the value of t? 1) x = n+3 2) 2x = 32 I realize 1 and 2 by themselves are not sufficient which is obvious. But the approach I took gives me two solutions, making it answer choice E, but the official answer is C. What i did:...

The prices seem to be the same, so the real differentiation is the service, the success rate and the effort they put in plus attention they give you as a client. I'm applying to European schools mainly from Nort...
