Electing to bat, Jammu and Kashmir batsmen failed to put up a big total as they folded for 119 in 19.1 overs at Nehru Stadium.
Bandeep Singh was top scorer for them with a 33-run knock that came off 32 balls with one four and two sixes. Openers Shunham Khajuria (15) and Ian Dev Singh (18) provided a fiery start but once they were dismissed their innings fell apart.
Tripura kept losing batsmen and never put up a strong partnership but the target was not big enough to be in real trouble.
Opener Singha played solid from one end, scoring a bulk of the runs in the Tripura chase. His 45 came off 42 balls with six boundaries, including a six.
Manishankar Murasingh (23) and Majumder (12) took the side to finish line after being reduced to 89 for six in 16th over.
