- 27 Feb '07 08:10 / 3 editsThere are 50 animals. Some are parakeets and some are dogs. The 50 animals have collectively 140 legs. There are no gimped animals with less than (or more than) the usual number of legs. How many are dogs and how many are parakeets?

Explain in detail how you solved it. This problem was given to elementary school kids who had not yet taken any algebra, so no algebra allowed. - 27 Feb '07 14:56

First assume how many legs if all dog, 50*4=200. 200-140=60*Originally posted by geepamoogle***50 animals, 100 legs minimum, extra 40 legs must be dog legs, which means 20 dogs, 30 parakeets.**

Yeah, there was math involved, but that's how I solved it.

60/2=30 parakeets, 50-30=20 Dogs (20*4=80), 80 legs +60 legs=140
