On a farm you have chickens and 3 legged cows you have 107 heads and 224 legs how many chickens do you have?
This can be done in your head: If all animals were cows there would be 321 legs. Every cow replaced by a chicken reduces this figure by one.The total reduction is 97 (321 - 224) so there are 97 chickens (and 10 cows)Check legs: (97 x 2) + (10 x 3) = 194 + 30 = 224. QED
