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