'Statement 2 is insufficient. The logic is the same as in Statement 2. Consider \(K=1\) (the answer is YES) and \(K=0\) (the answer is NO).'

In [highlight]statement 2 if we put value k=0 we will get 1>0. which is true. how is this a No

Your target is to find whether K can be negative or Zero or it is only positive. Remember you have to maintain the condition in statement 2

Now if K is positive, say k=1 statement 2 becomes 1+1> 1 which is true. That means by keeping k positive you can satisfy statement 2

Now if K is negative, say k= -0.5, statement 2 becomes -0.5+1> 0.125 or 0.5> 0.125 which is also true. That means by taking K= negative value you can still satisfy statement 2.

So, K can be positive and negative and zero. Therefore The answer of the question (IS K Positive) can be yes and can be no. Sot sufficient
