Truth or Lie Island
I am an explorer from Aza-aza island. In the middle of my journey, I met three people, called A, B, and C. The three people come from either Truth Island or Lie Island. I heard from my friends that people from Truth Island always tell the truth, otherwise, people from Lie Island always tell the lie. But, I missed some words when they started to introduce their selves to me. Help me to guess it. This is the part of our conversation.
A: I come from ….
B: ‘A’ is from Lie Island.
C: You are a liar.
Can you guess what ‘A’ said to me?
It doesn’t matter where is ‘A’ come from or Is ‘A’ lying or not. Because it will be the same answer.
Notice that the situation can be divided into two case:
‘A’ is from the Truth Island, so ‘A’ will said the truth that he come from Truth Island.
‘A’ is from the Lie Island, so ‘A’ will said the lie that he come from Truth Island.
