What is the value of x/y?

by tparekh » Fri Sep 05, 2008 11:39 pm
I think I saw this DS question in a Kaplan book:

Q. What is the value of x/y ?

1. x - y = 14
2. 2x = 5y

The answer is "B", but i did not choose that as I did not
know whether or not x & y were non-zero. Hence did not
get x/y = 5/2. Is something wrong in my assumption?

thanks,

Nothing wrong with your assumption- and yes, the answer should not be B for that reason. You would not see a question just like this on the real GMAT, however; on the GMAT, they would make clear in the stem that xy is nonzero.
