On the first day there are 27 possible different types of breakfasts, and 4 are chosen without replacement.
On day 2, there are 23, of which 4 are chosen.
3: 19
4. 15
5. 11
6. 7 (of which 4 are chosen, leaving 3)
7. 3 Not enough, one must overlap.
Thus, they can only go 6 days before repeating a breakfast.

There are 27 possible combinations of breakfasts. There are 4 people. So if you divide 27 by 4 you will get 6.75, making it 6 and a bit days. Therefore, on the 7th day someone would have to repeat one of the breakfasts.
I think thats right :P

This is a logic puzzle. You need to find a book that teaches logic. It is a great skill that can be learned and will greatly increase your scores of IQ, and all other kinds of tests. You should take the challenge

Is this a math problem or a spelling/grammar problem?
