Data Sufficiency

swerve wrote:Paul, a painter, paints only flowers or cats in his notebook. The pictures are drawn in either regular pencil or in charcoal (but not in both.) The total number of pictures in Paul's notebook is 39 greater than the number of cat pictures painted in pencil. How many flower pictures drawn in charcoal are there in the notebook?

1) There are 7 flower pictures drawn in pencil in the notebook.
2) There are 11 flower pictures drawn in charcoal in the notebook.

The OA is C

Am I missing something? Statement 2 tells us the exact answer to the question.

I assume it means to ask how many *cat* pictures in charcoal there are. Since we know the 39 pictures mentioned in the stem consist precisely of flower-pencil, flower-charcoal, and cat-charcoal pictures, then once we know how many of the two flower pictures there are, the rest, or 39-7-11= 21, must be cat-charcoal pictures, and then the answer would be C. But as written the answer is an instant B.
