140 and I've always really sucked at math. I answered I don't know on at least 5 questions. The one I went over the longest was the one where someone cheated and someone was a liar. None of the choices offered could be correct, the way I read it.
Same thought here about that question:
Four (A, B, C and D) suspect were interrogated:
- A: C won't cheat unless B cheated.
- B: Maybe one of A or C cheated.
- C: B didn't cheat, it's me cheated.
- D: B cheated.
Only one person can be the liar, which one is correct:
1 C lied, B cheated
2 B lied, B cheated
3 A lied, C cheated
4 D lied, C cheated
If it's #1, C lied, B cheated, then B's statement is also a lie, so it's not that.
If it's #2, B lied & cheated, then C also lied.
If it's #3, A lied, C cheated, then D also lied.
If it's #4, D lied, C cheated, then A also lied... unless there are multiple cheaters? I guess that's what we're supposed to assume?
