Question 1
You are on an island with two tribes.
One tribe always tells the truth, and the other tribe always lies. You meet
three individuals from the island A, B and C. Each individual belongs to one of
the tribes. You ask each of them the same question “Is B a truthteller?” “Is
B a truthteller?”
A says, “Yes B is a truth-teller.”
B says, “No, I am not a truth-teller”
C. Says, “B is a liar”
Given that each individual is either a
truth-teller or a liar, who is telling the truth?
