Help to understand the solution
Can you please help me understand solution to below question:
What is the value of the sum of positive integer x and positive integer y?
(1) The sum of x and y is equal to the sum of p and q which is equal to the sum of a and b.
(2) a + b = y – q
- Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
- Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
- BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
- EACH statement ALONE is sufficient to answer the question asked.
- Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

Hi niksdoon,
I dont think answer should be C. According to me, answer should be E. Since you have mentioned that is the GMATonthego question. let me have a look at it, there might be some mistakes or typo errors. Thanks for letting us know. Sorry for the confusion.
I also dont understand the point of this question here,
Question: x+y ?
Statement I is insufficient:
x+y = p+q = a+b
We dont know the values still. So insufficient.
Statement II is insufficient.
Nothing about x.
together
x+y = y – q
x+q = 0
But still we dont know anything about “y” value.
I could have,
x+y = p+q = a+b as
4+3 = 11-4 = 4+3
5+4 = 14-5 = 5+4
So cant say the value of x+y.
I think the question meant to ask x+q ? if so then the answer is C.
