The number of eggs in a basket doubles every minute. If it’s full of eggs in an hour, when was the basket half full?
At 59 minutes. The eggs double every minute, so half full would be a minute before it was full.

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
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 word with horizontal symmetry is one whose letters are a mirror image of themselves. If you drew a horizontal line across the word and folded it over, it would overlap on itself. For example, EXCEEDED and ICEBOX have horizontal symmetry, but VERTICAL and SIMPLE do not.
What is the longest word with horizontal symmetry?

The 22nd and 24th presidents of the United States of America had the same parents, but were not brothers. How is this possible?
It was the same guy! Grover Cleveland is the only president in history to serve two, non-consecutive terms.
