here is an old riddle:A farmer is raising cows and chickens. The animals have a total of 23 heads and 74 legs between them. How many cows are there? How many chickens?

Chickens:11

11*2=22

Cows:13

13*4=52

23 heads = 74 legs

cows = 1 head + 4 legs so

lets try 10 chickens and 13 cows

that would be 20 chicken legs + 52 cow legs = 72 legs thats very close

so if we do 9 chickens 14 cows we get

18 chicken legs + 56 cow legs = 74
