Data Sufficiency

If n is a positive integer is n equal to 100?
(1)sqrt(n) >9
(2) sqrt(n)>11

[spoiler]OA : Given as E[/spoiler]

I would go with B and may be I am having a brain freeze.....

Looks B to me as well.

Thanks Ojha.

My answer is B as well.
Something wrong with the OA ?

Hi Cramya,

You are right. The answer should be B.

I am surprised you guys were chosing B.
The question is asking "is a positive integer is n equal to 100" not greater than 100.


1) Sqrt(n) could be 10 i.e 100 or 11 i.e 121,12 i.e 144, 13 i.e 169 so insufficient

2) Similarly, sqrt (n) could be 12 i.e 144, or 13 i.e 169

The best answer is E

I get E pretty clearly as well. Unless their is a typo in answer (2) without a doubt E. :

2) Similarly, sqrt (n) could be 12 i.e 144, or 13 i.e 169

This clearly tells that n not equal to 100.
Answer is No

and hence B

I found the question posted on two forums other than BTG.

on testmagic, they have statement 2 as (2) sqrt(n)>11.

If this is the case then the answer would be B.

On gmatclub, the 2nd statement is posted as (2) sqrt(n)<11.

If this is the case, then the answer would be E because n could be anything less than 121 but greater than 81.

Thanks for the clarification, Dmateer.
