Gangjee returned a clinical two-under-70 in round four to end with an impressive tournament total of 13-under-275 at the Chandigarh Golf Club.
Chandigarh golfer Sujjan Singh claimed tied second position along with Bangladesh's Md Zamal Hossain Mollah as both totalled seven-under-281.
Gangjee (67-71-67-70), the overnight leader by three strokes, was in control all through the final day. The 35-year-old hit his drive to the right on the second but managed to salvage a birdie after a good third shot and a 10-feet conversion on the green.
The only blemish on Gangjee's card was the bogey on the 15th as he found the trees on two occasions on that hole. The man from the Royal Calcutta Golf Club (RCGC) finally sealed his fourth professional title after a par-save on the 17th and an eight-foot birdie putt on the 18th.
This happens to be Gangjee's third title on the domestic circuit. Gangjee, who went through the rigours of playing on the Web.Com Tour in the United States in 2011 and 2012, also has a win on the Asian Tour that he achieved back in 2004 in China.
