All of us have come across tricky logical questions. Let's share them. here's how this thread works: I'll ask a question and people will try to answer it..once it has been answered correctly, anyone can ask another question Here's my question There is a room, with no windows and one door. There is no keyhole, and you cannot see under or around the edges of the door. The door is closed. Inside the room there is an exposed incandescent light bulb. The light bulb is off. Outside the room is a panel with three on/off switches. Only one switch will operate the light, the other two do nothing. You must figure out which switch operates the light. You are not allowed to dismantle anything. You may flip the switches on and off as many times as you want before you open the door, and there is no time limit. You can only open the door once. Once you open it, you can no longer touch the switches and you MUST say which switch is the right one. (AKA no trying a switch, opening the door, trying the next switch, etc.) Once the door is open, you can go inside the room So, how do you tell which switch operates the light? note: let's not google anything
flip any two switches, wait a while, flip one off, go in and see/touch bulb: if it is warm but unlit, the switch u just flipped off is the one. if it is lit, the other switch is it. if it is neither warm nor lit, it's the switch you didn't touch.
k, so: a stingy king owns a garden. stingy king doesn't want anyone in garden, so he stations a guard at the only entrance, with the following instructions: 1. ask anyone who wants to enter, "why are you here?" 2. if they tell the truth, hang them. if they lie, drown them. so this man is like k i wanna go inside the garden, #yolo. he walks up to guard, guard asks him the question, man answers - aaaand is allowed to enter the garden ? what did the man tell the guard?
