Here is one problem from an ancient Indian treatise.
If 1/5 of the bee swarm flew to lavender flowers, 1/3 to linden flowers, the triple difference of these numbers flew to the tree, and one bee continued to fly between fragrant ketaki and malati, then how many bees were there?
Explanations
1/3 is bigger than 1/5.
The difference between 1/5 and 1/3 is: 1/3 - 1/5 = 2/15. The triple of this difference is 6/15.
Add all three fractions:
1/5 + 1/3 + 6/15 = 14/15.
The remaining 1/15 is the one last bee.
Thus, the entire swarm consisted of 15 bees.
