Kindly explain how can Statement 1 be sufficient to answer the question

As per Statement 1 we get k>(n-3)/2

So if n=1 then we get k>-1. As K is a positive integer so a possible value of "k" from this inequality is k=1
the question stem does not state that "n" and "k" are different.

Hi,

It is important to be very very careful while making a Q on your own.
Q has to be clear, unambiguous and pertaining to GMAT
Two points..
1) a wrong Q will not only misguide you and water your time but also waste others time.
2) you have to look at what you are achieving in it. If you are a student, it is better to solve 5 Q rather than waste time in creating Q.
But yes if you intend to get into teaching GMAT, then go ahead but be careful.

2k>n-3....
n is 1, n-3 becomes -2 and k can take value as 1 or anything above 1..
So insufficient

Hi,

Thanks for pointing out. It was my mistake. I have modified the answer.

Thanks.

Hi,

I agree with you on both the points. I am sorry for the mistake. I'll be more careful in future.

Thanks.
