Three Philosophers Under a Tree

Three philosophers are taking a nap under a tree. While they’re asleep, a small boy smears their noses with red berries. When they awake, they each begin to laugh, thinking the other two are laughing at each other.

But then one philosopher stops laughing, realizing his nose is red too. How did he come to this conclusion?

Let’s call the philosopher’s A, B and C. A reasoned that B was confident his nose wasn’t red. If B saw A’s nose wasn’t red, he would be surprised that C was laughing, because C would have nothing to laugh at. But B wasn’t surprised, therefore, A correctly reasoned his nose was smeared.

A Trail of Silver

If you carried my burden, you would be crushed.
Though not rich, I leave a trail of silver.

What am I?

A snail. They carry their homes on their back, and a house would crush a person (even the tiny houses). And the trail of silver is a bit of a stretch, but it’s the slimy, gooey substance snails leave behind them.

Has a Mouth But Cannot Drink

Has a mouth but cannot drink.
Has a head but cannot think.
Has a tongue but not a lung.
Some are held and some are hung.

A bell.

Word Value Of 52

If every letter of the alphabet is worth its numerical value (A=1, B=2, C=3), what’s a common 11-letter word whose letter values total only 52?

Abracadabra

An Animal of Few Letters

I am an animal of few letters,
Remove the second and you can’t see,
Change it to “l” and I’m a punishment,
Yet backwards I’m a game.

What am I?

Frog. It only has four letters, removing the “r” leaves fog, which makes it hard to see. Changing the “r” to an “l” makes flog, a punishment I hope you’ve never experienced. Flog backwards is golf, a game some would call a punishment when you keep swinging away at the ball yet it remains perched on its little white tower of terror while the other golfers impatiently wait for you to tee off.

A Third of the Way But Only Halfway There

You’ve traveled a third of the way, yet you’re only halfway there.

Where are you going?

Hint: The answer applies in the US but not in Europe.

You’re in a build headed to the fourth floor. When you reach the second floor, you’ve gone one floor and have two more floors left, so you’re 1/3 of the way. But at the same time, you’re on the 2nd floor and have two more floors to get to the 4th floor, thus you’re halfway there.

This doesn’t work in Europe, because they typically refer to the “first floor” as the ground floor, and the first floor is one story up.

Thanks to Danny Llinas for submitting this.

Dry As a Bone

Milton was out for a walk when it started to rain. He did not have an umbrella and wasn’t wearing a hat. His clothes were soaked, yet not a single hair on his head got wet. How did this happen?

Milton sadly suffers from alopecia, more commonly known as baldness. The old coot was as bald as a ping pong ball, leaving not a single hair on his head to get wet.

Largest Product

Using all the digits from 1 to 7, what two numbers have the largest product? For example, 1234 x 567 = 699678 but you can do much better than that.

742 x 6531 = 4,846,002.

A similar problem can be found in L.A. Graham’s Ingenious Mathematical Problems and Methods with a range of 1 to 9, but the principle remains the same – the numbers with the smallest difference produce the largest product. You start out with the highest two digits, 7 and 6, then attach 5 and 4, putting the smaller of the two digits with the larger number, giving you 74 and 65. The next two highest digits are 3 and 2, giving you 742 and 653. Finally, you add the 1 to the lower number. Page 80 has the details of that solution.
