Delhi cueist Madan, the national six-red no.1, found no answer to the rampaging form exhibited by the Mumbai-born Mehta, and went down tamely.
India's lone snooker professional Mehta, of Petroleum Sports Promotion Board, was unstoppable as he started off with a half century break and then followed it up with a superb run of 116 in the second to exercise early dominance.
After taking a 4-0 lead, Mehta dropped off a bit and allowed his rival to win the fifth frame. He stayed in the game before hitting the groove again with runs of 84 and 88 to virtually kill the contest.
Mehta had won the Chennai leg of the series to qualify for the 32-man draw here.
Madan, who beat Dharminder Lilly of Punjab 6-2 in the semifinal late last night, took home the runners-up prize money of Rs 1.3 lakh.
Losing semi finalists Lilly and Laxman Rawat, who was blanked 6-0 by Mehta, were richer by Rs 50,000.
