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