Q. Who among the following ruler was contemporary of great philosopher Madhavacharya?
Answer: Balban
Notes: The meeting of famous exponent of Dvaita philosophy Madhavacharya and Balban happened when Balban along with his forces camped on North Bank of Ganga river; and had forbidden anyone to cross river without permission. However, Madhavacharya along with disciples crossed the river. The soldiers of Balban wanted to arrest Madhava but he commanded them to be quiet; and told them that he wanted to see Sultan. This was followed by a meet between Madhava and Balban in which Madhava told Balban in chaste Persian about the Dvaita philosophy. Balban was impressed with Madhavacharya and offered him gifts, which Madhava declined.
