An aged cat saw three chickens walking merily somewhere in a house.
She hid herself in a close place wherefrom she could easily catch at
least one chicken.Suddenly she heard one of the chicken leading the two
saying."there are two chicken behind me."The chicken at third place instantly
said,"I have two chicken in front of me."The cat was about to jump over the
third one when the chicken in the middle said,"nothing surprised! there are
two chickens in front of me and two chickens are behind me." "How it is
possible?" the cat fell into deep thought and the chickens ran away.
The question is:-
a) how many chickens were walking?
b)where they were walking?
