Question

There is an animal farm where chickens and cows live. All together, there are 95 heads and 220 legs. How many chickens and cows are there on the farm?

Answer 1

The answer is 95 I think I might be wrong lol

Answer 2

Let c be the number of cows and h the number of chickens (hens). There are 65 heads so

c + h = 65.

Each cow has 4 legs, each hen has 2 legs and there are 226 legs in total so

4c + 2h = 226.

Multiply both sides of the first equation by 2 and subtract it from the second equation to get

2c = 96 and thus c = 48.

From the first equation it then follows that h = 65 - 48 = 17.

sorry if its wrong
