Question 1

Gaurav: 'At least 2 of us are liars' Neha: 'At most 3 of us are liars' Farhan: 'Exactly 2 of us are liars' Rohan: 'Sunil is a truth-teller' Sunil: 'Gaurav is a liar' What is the minimum number of liars?
Let L = number of liars.

Statement constraints:
1. Gaurav: L ≥ 2
2. Neha: L ≤ 3
3. Farhan: L = 2
4. Rohan: Sunil is truth-teller
5. Sunil: Gaurav is liar

From statement 3, L must be exactly 2 for that statement to be true.
But statements 1 and 2 are consistent with L=2 as well.
Now check statements 4 and 5:
If L=2, then 3 truth-tellers exist.
Statement 5 says Gaurav is liar - if true, then Gaurav is liar.
Statement 4 says Sunil is truth-teller - can be true.
This configuration is possible with L=2.

Can L=1? Statement 1 would be false, so Gaurav would be liar.
Then statement 5 (Sunil says 'Gaurav is liar') would be TRUE.
So Sunil would be truth-teller. Then statement 4 (Rohan says 'Sunil is truth-teller') would be TRUE.
