[Solved] A drove of sheep and chickens have a total of 99 heads and feet. There are twice as many chickens as sheep. How many of each are there?

This riddle has been around for some time on internet platforms such as Instagram, Facebook, and WhatsApp, and many people still argue over what the answer might be, as there are many possibilities. The correct answer is There are 9 sheep and 18 chickens. Let S be the number of sheep and C be the number of chickens. So: 2S = C 5S + 3C = 99 We can rephrase the first equation, so: 6S – 3C = 0 And then we can add this to the second equation, which yields: 11S = 99 By solving for S, we find that S equals 9. By substituting back in one of the original equations, we find that C equals 18. So there are nine sheep and eighteen chickens.
