Either is sufficient to answer that X is greater or equal to Y; while all being positive.[/strike]

Agreed; A
B is insufficient.

BTW about the approach towards such question; one such is to be on GMAT Club...!
MGMAT inequalities is supposed to be...

If x, y, p, and q are positive, is x>=y?

Question: is \(x\) more than or equal to \(y\) (is \(x\geq{y}\))?

(1) \(\frac{px}{qy}=\frac{p}{q}\) --> reduce by \(\frac{p}{q}\) --> \(\frac{x}{y}=1\) --> \(x=y\), so we can answer yes to the question: \(x\) is equal to \(y\). Sufficient.

(2) \(xy=p\) --> Clearly not sufficient (if \(x\), \(y\) and \(p\) equal to 1, 2, and 2 respectively then the answer is NO but if they equal to 2, 1 and 2 then the answer is YES).

Answer: A.

Hope it's clear.

A.

(1) px/qy = p/q

pxq = pyq --> x = y

SUFFICIENT

(2) xy = p

NOT SUFFICIENT

However in the first statement it is not greater than y as in the condition x> y is not fulfilled. How can we still go ahead and mark A as the correct answer.

Kinda confusing.

Can we use this logic for any similar question we encounter in the exam?

The question asks whether \(x\geq{y}\). (1) says that x = y, so the answer to the question is YES.
