Hi,

I agree that D is the correct answer. But isn't it true that in DS, the two statements never give contradict answers to the question given in the stem? Here statement (1) gives a definite YES while statement (2) gives a definite NO to the question.

Can I expect to see such contradiction in the real test?

Hi,

The actual GMAT will never give you contradictory answers for the two statements..

But having said that this Q too gives you 'YES' in both cases.. You are actually deriving and then reaching what is directly given in I..

1. n > 2

2. \((\frac{1}{10})^{(n−1)}<.1\) so \({(\frac{1}{10})^n}/{\frac{1}{10}^{1}}<.1\).. \({(\frac{1}{10})^n}<.1*{\frac{1}{10}\) =>\({(\frac{1}{10})^n}<.01\).. so n>2.. same as Statement I _________________
