Quant: "the difference between x & y" [#permalink]
28 Jun 2016, 10:22
Question Stats:
0% (00:00) correct
0% (00:00) wrong based on 0 sessions
On the GRE, if we encounter a question that states that: "The differences of X & Y is 4" does it mean:
Xy=4
OR
YX=4
Or We need to take both situation 1 & Situation 2 into account and solve for X &Y
I'm asking because some study guides tell us that we need to assume scenario 1, but I find it odd.

Regards, Why can we not write the statement as xy ? Because the question stem states the difference between x & y. It doesn't state xy or yx

It depends on the question. It can be Y  X, depends on the question. This can be a productive conversation if you have particular Questions as examples. Regards,

"The differences of X & Y is 4" means that "The differences of 10 & 6 is 4" for example.
You need to assume scenario 1.

Yes, it will be great if you can give some examples because I highly doubt that GRE will have a question just with that sentence. They will be providing more infor for a question like this.

One of the examples I found was in Barrons book. " If a is equal to the sum of b and c, which of the following is equal to the difference of b and c? A. abc B. ab+c C. ac D. a2c E. ab2c" The answer considers it to be bc and not vice versa.

Hey @kruttikaaggarwal, Refer page no: 17 of "Math Conventions" released by ETS (Testmaker of GRE) It says: " Unless otherwise indicated the phrase "difference between two quantities" is assumed to mean positive difference", that is greater quantity minus lesser quantity.You can get the pdf here: https://www.ets.org/s/gre/pdf/gre_math_conventions.pdfHope this helps
