Muzumdar, who compiled 112 in Mumbai's massive first innings score of 600 for 9 declared, followed teammate Wasim Jaffer, who made 122, into the books with three tons in the national championship.
Muzumdar, who batted for close to six hours and struck 13 fours, also put on 144 runs for the fifth wicket with Bhavin Thakkar, who made 82 in less than three hours, as the hosts ground the visitors attack and hopes to dust on a featherbed of a track at the Wankhede Stadium.
The Delhi attack was so listless that Wilkin Mota remained unbeaten after making 55 in two hours.
Delhi's most successful bowler was skipper Ajay Jadeja who had an impressive analysis of 4 for 59 even as his three frontline bowlers - Ashish Nehra, Sarandeep Singh and Rahul Sanghvi - conceded over hundred runs each for modest returns.
The home team, who started the day at 350 for three, later took one Delhi second innings wicket for 37 and ended their league engagements with an impressive tally of 23 points. Delhi failed to add to their pre-match aggregate of 12.
