in a zoo there are
2 wolfs
2 tigers
2 lions
2 sheep
we need to house them in four cages (two animals in each cage) by these rules:
A.in one cage we need to house a wolf and a sheep.
B.we can't house two animals of the same kind in one cage.
which one of these arguments in necessarily true:
1.at least in one cage a lion and a tiger will be housed.
2.at exactly one cage a lion and a sheep will be housed.
3.at exactly one cage a tiger and a sheep will be housed.
4.there is another cage in which a sheep and a wolf will be housed.
what is the simplest way to solve this question??
i found one combination for each argument
and tried to find common stuff between them.
regarding answer 1:
|wolf ,sheep |lion,tiger|sheep,lion|wolf,tiger|
regarding answer 2:
|wolf,sheep |sheep,lion|wolf ,tiger|lion,tiger|
regarding answer 3:
|wolf,sheep |sheep,tiger|wolf ,lion|lion,tiger|
regarding answer 4:
if we put a fifth cage it leaves us with 4 animals
we can't put two animals in each one of the four left cages
if we left with only fours animals,so its not possible.
i found that a lion and a tiger in one cage is the common thing among these three combinations.
but i can't think of three combination in order to solve this kind of question
it takes too much time.
is there any easier way??
