Edit: *Jeremiah *won **$790**, *Philemon ***$1650,** and *Ridgeley ***$464**

This is an easy one... how many can get it first time?

]]>OK, so recently I made up a way of sending coded messages and I was just wondering how difficult it would be for someone to crack.

So let's say, for example, that you are in the army and you caught a suspected spy and you found a slip of paper on him with those numbers on it, exactly as they are above. ]]>

Perhaps this is a good place to get the problem solved?

The question involves a 3x3 matrix and there is usually a logic sequence going from left to right, and sometimes also up to down. The idea is to supply the missing corner chosen from the eight samples below.

Been trying to crack it for days to no avail. Thanks for all the suggestions!

]]>She said I was a genius. But I said there were two ways to arrive at the answer, and I simply chose the easier way.

A 6-inch [long] hole is drilled through [the center of] a sphere.

What is the volume of the remaining portion of the sphere?

The hard way involves calculus. The easy way uses logic.

Hints:

Spoiler

Letters in the alphabet can be assigned with numbers...

Spoiler

What if you used the prev. hint on BHB

Spoiler

Maybe you can count letters in a phrase with numbers... come on mate I basically just handed it to you there

Answer:

Spoiler

yay (BHB = 282 in the alphabet, go to the letters 2, 8 and 2 in the message My cat is amazing and you get yay)

You have a pet mouse. It's an awfully cute mouse. Kind of like those mice on Pinky and the Brain. And you'd like to make it even cuter by teaching it some tricks. The only problem is that your mouse is, well... let's just say it has the brain of a mouse so it's kind of hard to teach it any tricks. But it is very good at eating food. In fact, it will always manage to find the closest morsel of food and go eat it, then find the closest from its new position and go eat that, etc. until it eats everything in sight. So, you'd like to "teach" your mouse to do some tricks given that behavior.

The first exercise is to place morsels of food at the corners of a square and place breadcrumbs so the mouse runs to diagonal corners as much as possible. In other words, suppose you have a square with points A, B, C, D in clockwise order with the mouse starting at point A and you'd like to make the mouse go to point C (diagonal from point A), then point B (one of the two remaining), then point D (diagonal from point B). There are already some breadcrumbs at points B, C, and D (since there need to be breadcrumbs there if you want the mouse to stop at those points) and your goal is to place breadcrumbs to make the mouse go from A to C to B to D while placing as few breadcrumbs as possible.

That first exercise might be a challenge for your kid brother, but for a BrainDen level challenge (the one I haven't convinced myself I've found an optimal solution for yet): Instead of a square, suppose you have a regular pentagon with points A, B, C, D, and E in clockwise order and want to get the mouse to go from A to C to E to B to D?

The soldiers have various injuries and can only cross the bridge so fast.

The following are the fastest times that each can cross:

MSGT Moore: 1 minute

1LT Jackson: 2 minutes

PFC Diggs: 5 minutes

CPT Pruden: 10 minutes

What is the fastest time they can achieve in all safely crossing the bridge?

]]>A family have been stuck in bank holiday traffic for the last four hours.

In the first hour they covered two fifths of their total journey.

The next hour they covered one third of what was left.

The following hour they covered one quarter of the remainder,

and in the fourth hour half of the remaining distance.

The family still have 20 miles left to travel.

How many miles have they travelled so far?

]]>For your amusement, here's an interesting spin on this genre:

One night you encounter a two-hour traffic delay due to an accident (the tow truck had difficulty clearing the road.) So, for a * time interval* 13 of two hours you were constrained to travel at 0 mph. You called home and said, sorry dear, but I'll be two hours late getting home.

The next night, for some unimaginable reason, you were also constrained to travel part of the way at 0 mph, this time for a * distance* of one inch. What do you say now when you call home?
