2 Bee or Not 2 Bee

Out of a swarm of bees one-fifth part settled on a blossom of Cadamda, and one-third on a flower of Silend'hri; three times the difference of these numbers flew to the blossom of a Cutaja; one bee which remained, hovered and flew about in the air, allured at the same moment by the pleasing fragrance of a Jasmin and a Pandanus. Tell me, charming woman, the number of bees?
