DS problem ?

[wind]

if x and y are 2 positive integers , x/y = ?
1.x=6
2.x^2=y^2

I answered it B but it was wrong!!!

if you answered B, that means you thought statement 2 would give you an answer to the question "what is x/y?"

did you get a value of 1 for x/y? you may have overlooked the fact that -1 is also a possible value. what if x = 3 and y = -3 ? keep in mind that when the GMAT says x^2 = y^2 that means that their absolute values are equal, but the numbers could have opposite signs..

statement 1 could give any answer so its not sufficient.
statement 2 again could give 1 or -1 as answer
both together will give the answer as 1 or -1
so answer is E. HOPE im right!

yes I did not consider the -ve value , but this is bec. the question stem mentioned x and y are +ve integers

impossible. not if B was listed as a wrong answer. can you post a screen shot of the original problem? meanwhile, all students who read this thread are advised to treat this problem and all discussion up to this point as though there were no restriction on what x and y could be (i.e. ignore the words "positive integers" in the original post)..

sorryyyyyyyyyyyyyyyyyy Tim yes I got confused with another problem :yes the question mentioned they were non zero numbers not positive integers . I tried to enclose a snapshot but I couldn't !!

Thank you so much for your kind help and sorry for bothering you :)

no problem. thanks for clarifying what the problem said.. :)
