Question 1
Amit says: 'Pooja is a truth-teller'. What type of person is Amit?
Amit says: 'Pooja is a truth-teller'. If Amit is a liar, then the statement is false, meaning Pooja is a liar. This creates a consistent assignment where both are liars. If Amit were a truth-teller, the statement would be true, making Pooja a truth-teller. Both assignments are possible, but the question asks for Amit's type. The configuration has a consistent assignment where Amit lies, so Amit is a liar.
