Aditi, who played the week without a practice round as her bags arrived late, totalled four-over 292.
Aditi, who was T-21 at the Lalla Meryem Cup last week, has had a good start to the season despite missing the cut in her first tournament in New Zealand. After three events, Aditi is now 39th on the Ladies European Tour Order of Merit.
Aditi was happy with the way she played in the tough conditions.
On the number of birdies, she had, Aditi said, "I made five birdies in the final round, which was good. In total I made 12 birdies over four rounds but I made a few errors over the four day rounds and that cost me a few shots. Hopefully I can build on this and work on my game for the next few days."
