In a certain game, scoring plays result in 2, 7, or 11 points only. How many times did a team playing this game score 2 points on a play?
1) The team scored 7 points on a scoring play exactly 3 times. 2) The product of the point values from all of the team's scoring plays is 6860.
This question is listed in "Math Workout for the New GMAT", 4th Edition, The Princeton Review, as a high level GMAT question.
Is this actually a valid question? The product of the scores given in option 2 has a prime factorization of {2, 2, 5, 7, 7, 7}. The factorization contains one "5" and no "11's". I don't see how this is possible if 6860 is supposed to be the products of 2^x*7^y*11^z.
The original answer and explanation is based on this factorization, giving an answer of 2 scores of 2 points by the team.

Thank you in advance.
I think you have a valid point there. Though it might be a simple typo and the stem should read: "scoring plays result in 2, 5, 7, or 11 points only."
