Sisters
Logic puzzles require you to think. You will have to be logical in your reasoning.
If only one of these statements is true, how many sisters have I got?
1.) "I've got ten or more sisters."
2.) "I've got less than ten sisters."
3.) "I've got at least one sister."
Answer
None. If statement 3 is true, then statement 1 can also be true, and vice versa. Statement 2 can be true by itself, but only if I have no sisters.

| Nice teaser! Your teasers have all been pretty good so far, and I'm looking forward to a longer logic puzzle from you, because I bet it'll be a doozy!  |

| Fun, but 2 can still work. The puzzle says "How many sisters do I have?" Why can't it be none? |

| Drakar, I really don't understand what you are asking. Only one statement can be true. The only statement that can be true while the other two are false is statement 2 and that only occurs when there are no sisters. |
