Six-Sided Madness

How many hexagon shapes, in total, can you find in this puzzle? Clue: There are more than 45.

Great Place for Frogs!

In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half the lake?

First Things First

If you had only one match and you entered a room where there was a kerosene lamp, an oil heater, and some kindling wood, which would you light first?

Here Chick, Chick, Chick

A farmer was asked how many chickens he had sold at market that day. His reply was:

“I’ve had four customers today, and each bought half of my remaining chickens, plus a half chicken.”

The farmer sold all of his chickens at market that day. How many chickens did the farmer sell?

Greek Puzzler

See if you can cut this Greek cross into four pieces with only two cuts, and then arrange the four pieces to form a square.

Six-Sided Madness

There are 64 hexagon-type shapes in total—37 single hexagons, 19 hexagons which contain 7 smaller hexagons, 7 hexagons which contain 19 smaller hexagons, and 1 large hexagon which contains all of the smaller hexagons.

Here Chick, Chick, Chick

15 chickens

The first customer bought 15 ÷ 2 + ½ = 8 (leaving 7). The second customer bought 7 ÷ 2 + ½ = 4 (leaving 3). The third customer bought 3 ÷ 2 + ½ = 2 (leaving 1). The last customer bought 1 ÷ 2 + ½ = 1.

The fourth customer can only have bought one chicken, otherwise there would be some chickens left. The third customer bought all but 1, so total - (total ÷ 2 + ½) = 1. This can be solved algebraically or it’s easy to see that the total must have been 3. This method keeps working until we reach the first customer.

Great Place for Frogs!

The patch doubles in size every day and so on the 47th day the patch will be half the size it is on the 48th day.

First things First

You would light the match first.
