Question 1
Sunil says: 'Deepa is a liar'. What type of person is Sunil?
Sunil says: 'Deepa is a liar'. If Sunil is a truth-teller, then the statement is true, so Deepa is a liar. If Sunil were a liar, the statement would be false, meaning Deepa is a truth-teller. Both are possible, but the question asks for Sunil'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 Sunil tells truth and Deepa lies. Therefore, Sunil is a truth-teller.
