Test 3, Question 14 [#permalink]

I'm sorry I couldn't find this question when I search for it.

Quote:

Is G < K ?

1. G > K^2
2. G and K are positive integers

* Statement (1) ALONE is sufficient, but Statement (2) ALONE is not sufficient
* Statement (2) ALONE is sufficient, but Statement (1) ALONE is not sufficient
* BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient
* EACH statement ALONE is sufficient
* Statements (1) and (2) TOGETHER are NOT sufficient

Statement (1) by itself is insufficient. Consider the following two examples which satisfy S1 but can't prove that G < K:

G=1/10, K=1/10 and G=1/3 , K=1/2

Statement (2) by itself is insufficient. We know nothing about the values of G and K.

Statements (1) and (2) combined are sufficient. For G > K^2 > 1 to be true, G > K.

The correct answer is C.

I don't get this question. I chose E. I cannot reconcile this statement in the answer explanation "For G > K^2 > 1 to be true, G > K". I say not necessarily. I can disprove that statement by using the info up above G < K if G=1/3 and K=1/2. So it's possible that G=1/3 and K=1/4 which means G > K and satisfies both statements while using G=1/3 and K=1/2 means that G < K and this satisfies both statements. It can go either way, resulting in a "maybe" to the original question. Am I missing something here?

It seems like you missed that G and K are integers according to S2
