If x and y are the positive integers, Is x>y? 12 Apr 2020, 18:40

Yes, both x and y can be equal to 1.
But in that case also, x is NOT greater than y.

Hence A is SUFFICIENT.

No, unless it is given that x and y are different, X and Y can be equal as well.

All have answered C or E and that shows we miss out on finer details at some time..

If x and y are the positive integers, Is x>y?
1) \(x^2 +12 = 13......x^2=1....x=1.. or.. x=-1\)
x is positive, so x=1...
Nothing about y-- of course there is something and that is ' y is a positive integer', so \(y\geq{1}\).
Also as x is 1, the lowest possible positive integer, it will never be GREATER than any other number..
Is x>y?......NO for sure
Suff

2) y is a multiple of 9
So y=9a...But nothing about x.
Say x=4....NO
But if x=20, then yes
Insuff

A
Hi, Chetan/Ghostbusters
Can we assume that x and y are DIFFERENT positive integers although it's not mentioned that x is not equal to y??

If, x and y can be equal (As it's not mentioned), then y can also be 1.[/quote]

Hi GMATinsight

The answer is not C. it is a trap question.

x=1 and y will be 1,2,3,4,5,6....etc

In all cases Answer is NO.

Hence answer is A

Official solution



If x and y are the positive integers, Is x>y?
1) x^2 +12 = 13
x^2 = 1
x = +/-1 but as per the question, x and y are positive integers, hence x = 1
1 is the smallest positive integer, hence 1 can never be greater than any other positive integer
Hence, we can say than x is NOT greater than y.

SUFFICIENT

2) y is a multiple of 9
y can be 9, 18, 27...
x is NOT known.
NOT SUFFICIENT.

Answer A

Not sure i follow statement 1 reasoning. Y could be 1 aswell? which makes insufficient information? Pls help.

If x and y are the positive integers, Is x>y?
1) x^2 +12 = 13
2) y is a multiple of 9

Solution:


(1) x^2= 1

x could be +1 or -1

Question tells us that x and y are positive integers, thus x=1
Well, honestly I don't think this is a clear question because:
1. If x>y implies that x is different from y means that y is bigger than x thus (1) is sufficient
2. If x>y doesn't implies it means that x could be >= y so (1) is not sufficient.

(2) clearly insufficient.

Together.
If we consider 2. in statement 1 and statement 2 they are sufficient.

So the answer could be A or C

x=1...
Now y can be >1..then x>y....NO
Also if y=1, then is x>y, that is - is 1>1, Again NO
