How many flowers do I have if all of them are roses except two, all of them are tulips except two, and all of them are daisies except two?
(In reply to
re(2): Already not the latest... another solution by Charlie)
I had the same thought -- you could have exactly two flowers that are not roses, tulips or daisies. However, I think Charlie's solution is the one the author had in mind. In that case, there should be language in the problem indicating that the speaker has no other kinds of flowers.
