Tell the Truth

Did he tell truth

Jimmie Dean visited an island. There were 2 tribes living on this island. The east tribal people always tell a lie. The west tribal people always tell the truth.

Jimmie Dean saw a guy passing him. He asked the tour guide to ask that guy where he lives. The tour guide asked the guy and came back with the answer: he lives over west. Did the tour guide tell the truth or tell a lie?

Solution

tell the truth or lie solution

If the guy was from the west, he should answer the truth: I am from the west.

If the guy was from the east, he also should tell a lie: I am from the west.

The answer will always be: I am from the west. So we know the tour guide was telling the truth.

Question

Life door or Death door

There is a prisoner who is about to be executed. The king decides to give him one last chance to live.

There are 2 doors, the life door and the death door. There is one guard standing by each door. Those two guards know which door is the life door and which is the death door. However, one of them always tells the truth and the other always tells a lie. There is no way you can identify which door is the life door or the death door. There is no way you can distinguish who is the one telling the truth.

The prisoner can only ask one guard one question. Then he needs to choose a door to walk in. If he walks in the death door, then he will be executed. If he walks in the life door, he can have a new life.

He did choose the life door and lived. What was the question he asked? How did he choose the door after he got the answer from one of the guards?

Solution

Triplet Brothers

There are 3 triplet brothers. They look identical. The oldest is John, he always tells the truth. The second is Jack, he always tells a lie. The third is Joe, he either tells the truth or a lie.

Jimmie Dean went to visit them one day. He was wondering who was who. So he asked each person a question.

• He asked the one who was sitting on the left: "Who is the guy sitting in the middle?". The answer was "He is John."

• He asked the one who was sitting in the middle: "What is your name?". The answer was "I am Joe."

• He asked the one who was sitting on the right: "What is the guy sitting in the middle?". The answer was "He is Jack."

Jimmie Dean got really confused. Basically, he asked 3 same questions, but he got 3 different answers. Would you find out who is who for Jimmie?
