- Three people check into a hotel room that costs $30. They each pay $10. The manager realizes the room should only have cost $25, so he gives the bellhop $5 to return to them. The bellhop pockets $2 and gives each person $1 back. How did they only pay $9 each ($27 total), when the bellhop only stole $2? Where is the missing dollar?
- Answer: There is no missing dollar. The flaw is in the calculation. The correct calculation is: The guests paid $27 total. The hotel received $25, and the bellhop received $2. ($25 + $2 = $27).
- You have two ropes, each of which takes exactly one hour to burn, but they burn inconsistently. How can you measure exactly 45 minutes? (You can light them at either or both ends.)
- Answer: Light the first rope at both ends (it burns out in 30 minutes). Simultaneously, light the second rope at only one end. When the first rope burns out, the second rope has 30 minutes of burn time remaining. Immediately light the second, remaining rope at its other end. It will burn out in 15 minutes, giving you 30 + 15 = 45 minutes.
- There are three light switches outside a closed room and three light bulbs inside. You can only enter the room once. How can you figure out which switch belongs to which bulb?
- Answer: Flip switch 1 on and leave it for a few minutes. Flip switch 2 on, and then immediately turn switch 1 off. Enter the room. The bulb that is on belongs to switch 2. The bulb that is off but warm belongs to switch 1. The bulb that is off and cold belongs to switch 3.
