100 Herbivores (Posted on 2002-06-10)

There are a total of 100 animals: cows, sheep and buffaloes. These 100 animals ate 100 bunches of grass.

Every cow ate 5 bunches, every buffalo ate 3 bunches and every sheep ate only 1/3 bunch.

How many cow, sheep and buffalo are there? You only know that there is at least one of every kind of animal.

A very thorough solution to this problem was posted HERE by Ender, and I won't bother repeating it.
To sum it up though, there are three possibilities:
Cows: 4; Bulls: 18; Sheep: 78
Cows: 8; Bulls: 11; Sheep: 81
Cows: 12; Bulls: 4; Sheep: 84
