Not the Sort That’s Eaten

I’m not the sort that’s eaten, I’m not the sort you bake,
Don’t put me in an oven, I don’t taste that great,
But when applied correctly, around me you will find,
Problems are so simple when my digits come to mind.

The Sun Bakes Them

The sun bakes them,
The hand breaks them,
The foot treads them,
The mouth tastes them.

Grapes. Grapes are grown in the sun, can be hand picked and crushed by feet (which is sort of gross) to make wine, which is tasted by your mouth when you drink it.

Frederick’s Epitaph

Frederick died after a long and productive life of 87 years, but this epitaph was written on his headstone:

Frederick lived a good long life,
He loved his children and his wife,

He was honest, kind and deserved nothing but praise,
Even if he only had twenty-one birthdays.

How is this possible?

He was born on February 29th in a leap year. Consequently, in his 87 years, he only witnessed twenty-one of his actual birthdays. The other years there was no February 29th.

Counterfeit Accounting

Early one morning Hal, the owner of a hardware store, sells a mailbox for $25 to Courtney that cost him $20 wholesale. Courtney pays with a $100 bill and Hal discovers he doesn’t have enough change. He runs to the jewelry shop next door, where Jack, the owner, gives him change in exchange for the $100. Later that afternoon, Jack discovers the $100 bill is a counterfeit and Hal pays him $100 to make it right.

What was Hal’s total loss?

The total loss was $95.
-$20 = The wholesale cost of the mailbox
$100 = The money from Jack
-$75 = The change paid to Courtney
-$100 = To pay Jack back
-$20 + $100 – $75 – $100 = -$95

It’s easy to think Hal lost $195 but that fails to account for the $100 used to make the change, which came from Jack, not Hal. Jack paid $100 in exchange for a worthless piece of paper, so the $100 was initially Jack’s loss. Hal had made a $5 profit until Jack’s discovery. If you guessed $100, that’s arguably correct, but not making $5 in profit isn’t a loss in the strictest sense of the word.

Copying Cassette Tapes

Joe and Andrea want to copy three 60-minute cassette tapes. They have a 2-cassette recorder to copy the tapes, allowing them to copy two tapes at a time. Each side takes 30 minutes to be copied, so two tapes can be copied in an hour and the third will take another hour. Andrea bets Joe she can copy all three tapes in 90 minutes. Does she win the bet?

In the first 30 minutes Andrea copies the A sides of tape 1 and 2.
In the second 30 minutes, she copies tape 1 side B and tape 3 side A (finishing Tape 1).
In the last 30 minutes, she copies tape 2 side B and tape 3 side B.
