Crazy Taxi Driver

A taxi driver runs through four red lights, two stop signs and goes through a house. A police officer witnesses this but doesn’t do anything. Why not?

The taxi driver is not in his cab, he’s out for a run. The house he went through was his own because he was done running.

Cut But Never Eaten

What is put on a table and cut but never eaten?

A deck of cards.  You put the cards on the table to play, and you cut the cards to mix them up, but you don’t eat them. Flowers is another possible answer.

Builds Its Table On My Shelf

From that which comes within itself,
it builds its table on my shelf.

A spider. The silk comes from within the spider, and the “table” (web) is often built in corners like there are on a bookshelf.

The Snooze Button

Why is it very common to have a 9 minute snooze interval on alarm clocks, why not 10 instead?

By setting the snooze time to 9 minutes, the alarm clock only needs to watch the last digit of the time. So, if you hit snooze at 6.45, the alarm goes off again when the last digit equals 4. They couldn’t make it 10 minutes, otherwise the alarm would go off right away, or it would take more circuitry.

Wily Winifred and the Case of the Odd Numbers

Mrs. Shine was having a rough day and wanted a break. So she asked her class to calculate the sum of the first 50 odd numbers. In a few moments, Winifred was at her desk with the correct answer of 2,500. Stunned, Mrs. Shine figured she must have gotten lucky, and sent precocious Winifred back to her seat with the task of finding the sum of the first 75 odd numbers. Again, Winifred returned in seconds with the correct answer (5,625).

How did Winifred find the answer so quickly?

Winifred, being the precocious child she is, realized there was a pattern when computing smaller sums of odd numbers.

First 3: 1 + 3 + 5 = 9
First 4: 1 + 3 + 5 + 7 = 16
First 5: 1 + 3 + 5 + 7 + 9 = 25

Do you see the pattern like our dear friend Winnie?

For the first n odd numbers, the sum is equal to n2. Thus the first 50 is 502, or 2,500, and the first 75 is 752, or 5,625.
