Alfred’s Tough Cash Request

Alfred is at the bank to cash his $200 check. He tells the cashier he would like some one dollar bills, ten times as many two dollar bills and the rest in fives.

How many of each denomination does the cashier need to give Alfred?

Five $1 bills, 50 $2 bills and 19 $5 bills.

We know that in order to give the rest of the amount in fives, the sum of the one and two dollar bills needs to be divisible by five (i.e. end in 0 or 5).

If we start with a single one dollar bill, we’d need ten two dollar bills to satisfy the request, making $21. But we need a sum that is divisible by 5. So we keep going up, like so:

$1 + $2 * 10 = $21
$2 + $2 * 20 = $42
$3 + $2 * 30 = $63
$4 + $2 * 40 = $84
$5 + $2 * 50 = $105 (Aha! It’s divisible by 5)
$6 + $2 * 60 = $126
$7 + $2 * 70 = $147
$8 + $2 * 80 = $168
$9 + $2 * 90 = $189

So the only option that works is 5 $1 bills and 50 $2 bills, leaving $95 (95 / 5 = 19) to be paid out in 19 fives.

Alfred is one tough customer.

A Circled of Joined Hands

You dance in a circle of joined hands,
And though they spin away I can always see your face,
In the world, no matter where I am,
One look at you and I know my place.

What am I?

A clock.

An analogue clock is a circle, and the hands of a clock are joined at the middle.
The hands can point away from you, but the clock face is always visible.
No matter where you are in the world, you can probably find a clock.
“One look at you and I know my place…in time!”

Thanks to Helena for creating this and sending it in.

It’s True I Bring Serenity

It’s true I bring serenity,
And hang around the stars
But yet I live in misery;
You’ll find me behind bars
With thieves and villains I consort
In prison I’ll be found
But I would never go to court,
Unless there’s more than one

The letter “s”.
