Problema Solution
if 96 chickens and goats are put together, they have the total 312 legs. how many chickens and goats are there?
Answer provided by our tutors
Assume that all 96 animals have at least two legs, and none are amputees. Therefore there are 192 legs accounted for.
There are an additional 120 legs left. These can only be in pairs, since chickens and goats have either two legs or 4
Therefore there are 60 extra pairs of legs.
60 animals are goats, and the remaining 36 are chickens.
