The Mysterious Island
The Mysterious Island
On a mysterious island, there are two tribes. One tribe always tells the truth, and the other tribe always lies. You come across two islanders, Alex and Bob. You know one of them is from the truth-telling tribe and the other is from the lying tribe, but you don’t know who is who.
Alex says: “We are both from the same tribe.”
Bob says: “We are from different tribes.”
Q. Who is from the truth-telling tribe and who is from the lying tribe?
If you are rushing to check the answer to this brain teaser below, my suggestion is to first try to figure out the answer on your own, then compare with the correct one. The correct answer along with an explanation is given below.
Solution:
Given the statements:
- Alex says: “We are both from the same tribe.”
- Bob says: “We are from different tribes.”
Let’s analyze the statements:
- Assume Alex is telling the truth:
- If Alex is telling the truth, then his statement “We are both from the same tribe” is true.
- But if they are both from the same tribe and Alex is a truth-teller, then Bob must also be a truth-teller.
- This contradicts the scenario because one is supposed to be a liar.
- Assume Alex is lying:
- If Alex is lying, then his statement “We are both from the same tribe” is false.
- This means they are from different tribes.
- If they are from different tribes and Alex is lying, then Bob must be telling the truth.
Therefore:
- Alex is the liar.
- Bob is the truth-teller.
So, Bob is from the truth-telling tribe, and Alex is from the lying tribe.
