There is a room with one door that contains three light bulbs inside and
three switches outside. The light bulbs and the switches are in no particular
order, that is, triangular or linear setting etc.... There are no kind of electrical
scheme whatsoever. If you are outside the room you cannot tell if any
of the light bulb in the room is on. In essence, there are no holes, openings
spaces, windows, etc... You are allowed to enter the room only once from which
you should be able to determine which switch will light a specific bulb. You are
not allowed to have any kind of instruments to aid you in your decision. All the
switches and light bulbs do work and one switch cannot put on two light bulbs; it
is one switch per bulb. You can flip any amount of swiches as you choose but
remember, YOU CAN ONLY ENTER ONCE. How would you go about determining
which switch will put on a specific light bulb?
If you have an answer or should I say..do
you give up? Here is the answer.
