i think that if you are gonna say there are twice as many 4 legged than 2 legged, etc, you should say somethin in there about there being a certain amount without ANY feet. cause saying about the 4 and 2 legged, makes it appear that those are the 2 options, and that doesn't work.
With 11 heads and only 20 feet, it is quite evident some are without feet.
I agree that there should have been a note about the snakes, or a general comment about animals with no legs.
Nah, the wording is fine. I was trying to find some alternate solution, but the only creature I know of with ten legs is a squid, and that's not a jungle creature.
Well if it;s OK to introduce snakes that weren't mentioned in the problem then why not a few 1 legged ducks? Plenty of them around.
4 x 1 legged ducks
6 x 2 legged whatsit
1 x 4 legged thingy
