Islanders logic problem

There are two enchanting but remote islands in the South Pacific. The islanders born on one island always tell the truth, and the islanders from the other island always lie.

You are on one of the islands, and meet three islanders. You ask the first one which island they are from, and he indicates that the other two islanders are from the same Island. You ask the second islander the same question, and he also says that the other two islanders are from the same island.

Can you guess what the third Islander will answer to the same question?


The Pigeon logic problem

Two friends decide to get together, so they start riding their bicycles toward each other. They plan to meet halfway in the middle. Both are riding at 6 MPH. They live 36 miles apart. One of them has a pet pigeon and it starts flying as soon as the friends start traveling. The pigeon flies back and forth at 18 MPH between the 2 friends until they meet.

How many miles does the pigeon end up travelling?

Answer to the islanders logic problem: The third islander will also say that the other two are from the same island. One of them is telling the truth about the other two being from the same island, but those two come from the island of liars so they both lie and say the other 2 men are from the same island. Of the three identical statements, only 1 is true.

Answer to the pigeon logic problem: 54 miles. It takes three hours for the friends to meet, and the pigeon flies between them at 18 MPH. 3 hours x 18 mph = 54 miles.
