There are eight rooms, each with a single door to go in and out.
Four of the rooms have light switches and four of them have light bulbs.
You can enter and exit each room exactly one time. After you leave a room, the door closes and locks behind you.
Your job is to determine which light switches control which light bulbs.6 AnswersTrivia1 decade ago
