This question is from GMATPrep
If a wire 27 meters long is cut into three pieces of three different lengths, what is the length of the longest piece?
(1) The length of the longest piece is twice the length of the shortest piece
(2) The sum of the length of the two shorter pieces is 15 meters
OA is "Statement (2) alone is sufficient but statement (1) alone is not sufficient"
I think, statement (1) alone is also sufficient, as the only combination that satisfies the condition in statement (1) is 12, 9, 6 and it gives us the answer.
I'm confused why OA is different than what I think it should be, please advice
Thanks
