In a zoo rabbits, parrots and snakes have 24 heads, 14 wings and 62 legs. How many snakes are there in this zoo?
Pick one
Solution
Rabbits and snakes have no wings and parrots have two wings each, so there are parrots in the zoo. Thus, the parrots account for legs. Snakes have no legs, so the rabbits have legs altogether. Each rabbit has legs, so there are rabbits in the zoo, as well as snakes.
