Question 1
Gaurav says: 'Neha is a liar'. What type of person is Gaurav?
Gaurav says: 'Neha is a liar'. If Gaurav is a truth-teller, then the statement is true, so Neha is a liar. If Gaurav were a liar, the statement would be false, meaning Neha is a truth-teller. Both are possible, but the question asks for Gaurav's type. Since we need a unique answer, consider that truth-tellers can make true statements about others, while liars make false statements. This configuration has a consistent assignment where Gaurav tells truth and Neha lies. Therefore, Gaurav is a truth-teller.
