Jatin and his friend Pawan had very famous challenge sessions at their school. One would suggest something they could do, and the other would prove it wrong somehow.
One day, Jatin surprised Pawan by stating: "I can answer any question in the world."
Sure that he would win the challenge, Pawan accepted the task of proving it wrong. He wrote up a test full of impossible questions. After a while, Jatin returned the test. Pawan unbelievably lost the challenge and told Jatin he could indeed answer any question.
How did Jatin win?
