My friend who owns a farm near Dallas had five droves of animals on his farm consisting of cows, sheep and pigs with the same number of animals in each drove. One day he sold them all to eight dealers. Each of the eight dealers bought the same number of animals and paid at the rate of 17 Dollars for each cow, 2 Dollars for each sheep, and 2 Dollars for each pig. The money he received in total was 285 Dollars.

How many animals did he own, and how many of each kind?

Edited for proper punctuation.

I assume that by "the same number of animals in each drove" and "bought the same number of animals" you mean the total quantity of animals regardless of species.

Ya, I agree. The price of sheep and pigs should be different in order to have a unique solution. Anyways, good job guys ...
