It was the fourth successive time that the two teams clashed in the final and India have emerged victorious on all four occasions.
Electing to bat first after winning the toss, India was helped by some good batting performances by Asha Rawat, who was fell short of a well-deserved century, and captain Mithali Raj, who scored a well-compiled 66 to post a formidable target of 261 for Sri Lanka.
However, the Indian bowlers did not give Lankans any chance to make a match out of it. The hosts were finally bundled out for a paltry 83 inside the 37th over. Pujare Seema and Neetu David picked up three wickets each.
At the start, India were off to a poor start as opener Jaya Sharma failed to open her account and departed in the second over.
Rawat then combined well with Kavita Jain (28) to stitch the innings before the latter was out with India at 75. Mithali then joined Rawat and both added a massive partnership and almost batted the hosts out of the game.
Rawat's 114-ball knock was studded with 12 fours and a six while her skipper hit six fours in her 72-ball essay.
At the end of the innings, Amita Sharma made a quick-fire 50 off 31 balls as India finally scored 260 for seven in their 50 overs.
