Kevin’s School Supplies

Kevin brings his school supplies to the counter. The cashier rings up his purchase for a total of $1.70. Kevin is puzzled, and says, “I bought 2 pencils at 2 cents each, 5 pencils at 4 cents each and 8 notebooks and 12 sheets of colored paper. I don’t remember the prices of the latter two, but the total can’t be $1.70.”

How did Kevin know?

Because 4 cents, 20 cents, 8 notebooks and 12 sheets of colored paper are all divisible by 4, but 170 cents isn’t.

A Four Word Admonition

What four word admonition makes the happy person sad and the sad person happy?

The phrase, “This too shall pass.” According to Wikipedia, the well-known phrase is often attached to a fable of a great king who is humbled by these words, and to someone who is experiencing something wonderful, it can be saddening. But to one who is in the pits of despair, it is a phrase that brings relief and hope.

In other words, if a happy person is told, “This too shall pass” it will make them sad. But to a person on hard times, hearing, “This too shall pass” will cheer them up.

Which Switch?

You are standing outside a closed door. On the other side of the door is a room that has three light bulbs in it. The room is completely sealed off from the outside. It has no windows and nothing can get in or out except through the door. On the outside of the room there are three light switches that control each of the respective light bulbs on the other side of the door.

Your assignment is to determine which light switch controls which light bulb. You are allowed to enter the room only once, and once you come out, you must be able to state with 100% certainty which light switch controls which light bulb.

Turn one light switch on, wait a few minutes, then turn it off and turn another light switch on. Go into the room and feel the light bulbs. The one that’s still warm is connected to the switch that you first turned on, the one that is on was the second switch you turned on, and the last bulb is controlled by the switch that you didn’t touch.

All Things Devours

This thing all things devours,
Birds, beasts, trees, and flowers.
Gnaws iron bites steel,
Grinds hard stones to meal,
Slays king, ruins town,
And beats high mountain down

Time. Iron, steel, stone and virtually any substance will be worn down given enough time.

(From J.R.R. Tolkien’s The Hobbit)

Nearly Hanging

A prisoner is told, “If you tell a lie we will hang you; if you tell the truth we will shoot you.”

What can he say to save himself?

You will hang me. If they hang him, then the statement was true and they could only hang him for telling a lie. If they shoot him, then it makes the statement a lie and they were only to shoot him for telling the truth. An alternate solution is to say, “You will not shoot me,” leading to the same quandary for the killers.

A Problem In Many People’s Lives

I am a problem in many people’s lives. At times (even more than once) I’m useful. The older I grow, the less useful I become. Who am I?

Credit or debt. Debt is a problem in many people’s lives, but in order to go to school or make a large purchase, it can be useful. As your debt grows older, it’s more unpleasant than useful.
