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.tparekh wrote:I think I saw this DS question in a Kaplan book:
