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.

Everyone Has It

Everyone has it.
Those who have it least don’t know that they have it.
Those who have it most wish they had less of it,
but not too little or none at all.

Age. Young children don’t even know their age and extremely old folks wish they could turn back the hands of time, but not so much that they’re too young or they no longer have an age at all.

Two of the Same Along the Way

This word starts with the same letter it ends with and there are two of the same along the way. There is another pair and one each of two more, just to make you smile. What is the word?

Giggling. It starts and ends with ‘g’ and there are two more ‘g’s in the middle. It also has a pair of ‘i’s and one ‘l’ and ‘n’. Plus, giggling makes you smile ;)

What one word goes with each of these to make a new phrase?

Strip

Fan

Out. Strip out is to remove parts from a machine. Ground out is when you hit a ground ball in baseball and are thrown out at first. Fan out is when something, such as cards, are spread out like a fan.

Thanks to Jeremy for solving this.

Everyone Is Doing This Same Thing

Right now everyone in the world, no matter where they are, is doing the exactly same thing. What is it?

Getting older. Sad but true, and there’s nothing anyone can do to stop it. If you thought of breathing, it’s not entirely accurate because not everyone takes a breath at the same time. Living is an arguably suitable alternate answer as well.

The Mystery Six-Digit Number

Find a six-digit number containing no zeros and no repeated digits that satisfies the following conditions:

1. The first and fourth digits sum to the last digit, as do the third and fifth digits.
2. The first and second digits when read as a two-digit number equal one quarter the fourth and fifth digits.
3. The last digit is four times the third digit.

192768.

If you call the number ABCDEF, then you get the following equations.

1. A + D = F and C + E = F
2. AB = DE / 4
3. F = 4 × C

The only numbers that work for C and E are 2 and 6 or 4 and 8, and in order to make F a single-digit number, we can deduce that C = 2, E = 6 and F = 8.

So far, our number is AB2D68.

We know A + D = 8 so A and D are both odd numbers. The only odd number less than 8 that we can use for D to make one-quarter of two-digit number D6 also be a two-digit number is 7, so D = 7 and A is 1. This makes the two-digit number AB 19.

The Long River

How many times does the letter S appear in the name of the longest river in the world?

Zero. The Nile is the longest river in the world. Some claim the Amazon as the longest, but that too has no “S”es (that looks weird but I don’t know how else to write the plural of “s”). The Mississippi is the 4th largest river in the world according to a href=”https://en.wikipedia.org/wiki/List_of_rivers_by_length”>Wikipedia.
