Hen, Corn, Fox Challenge

[singpeace]

You have a hen, a sack of corn, and a fox.

You must get them all three across a lake - one at a time.

If you take the corn, the fox eats hen.
If you take fox, hen eats corn.
If you take hen, fox doesn't eat corn, BUT if you next take fox, he eats hen when you go back for corn. BUT if you next take corn, hen eats corn when you go back for fox.

How do you do it?


I'll give the answer to the first person to respond - that is, if you don't know the answer already.

I remember this from Cog...

Hen to far shore.
Return empty handed.
Grain to far shore.
Return with hen.
Fox to far shore.
Return empty handed.
Hen to far shore.

I cheated.

I'm a psychology major, so I've taken cognition and memory and blah de blah.

I'm also a philosophy major so I've taken logic.

Take the hen across, go back and get the fox, take the hen back, take the grain across, then go back and get the hen.

ETA: Grats, Bushido! You beat me to it!

Shoot. Good job.

Take the hen across, go back and get the fox, take the hen back, take the grain across, then go back and get the hen.

I totally beat you.

Two answers in ten minutes at two in the morning. Welcome to the science forum.

This one is my favorite, but I've asked it here before:

Which is cheaper -- and why?

1. Take two atheists to the movies once.
2. Take one scientist to the movies twice.

Another one of my favorites:

Farmer Brown has 10 cows; he sells some, and now he has 12.

1. How many cows did Farmer Brown sell?

I'm so out of my league here.

So... here's a really dumb riddle:

A man goes up a mountain on Sunday, stays four days, then comes back down on the same Sunday. How did he do it?

'Sunday' is his horse.

Take two atheists to the movies once.

Three tickets.

Take one scientist to the movies twice.

Four tickets.

How many cows did Farmer Brown sell?

He sold two less than he bought.

Okay, instead of a riddlle here is the title of a song my ole' country dad wrote:

"You can lock me up in jail and throw away the key, but you can't stop my face from breaking out."


Peace.

 

[AV1611VET]

He sold two less than he bought.

Yup -- he sold -2 cows.

What superstar was actually a female who played a male; and what superstar was actually a male who played a female?

LOL -- thanks for the laughs, singpeace.

Reps ur way.

He sold two less than he bought.

See, that was just far too obvious, so I was just going to go with "they bred".

Take one scientist to the movies twice.

Four tickets.​

Gracchus, you assume that you buy a movie ticket for yourself. I routinely take my brother to school. That doesn't mean I sit through his classes with him. It is not a safe assumption that you buy tickets for yourself.

Factor in additional costs/savings:

Travel Expenses: Driving to the movies twice is going to be more expensive than doing it once. You save money by reducing the number of trips.

Opportunity Cost: Travel time doubles when we go to the movie theaters twice. Time spent watching movies / waiting in lobby also doubles if we watch two movies instead of one.

Discount Rate: Though the scientist's first movie could start immediately, the second viewing will have to happen at some point in the future and I should discount the cost of watching it.

Social Expectations: If I'm treating somebody by purchasing their ticket, it's also quite possible that I will be expected to purchase food for them at the concession stand.
​

I'm certain I missed some important considerations here. I don't feel like writing an equation to actually solve the question.

One day a group of Darwinian scientists got together and decided that man had come a long way and no longer needed God. So they picked one Darwinian to go and tell Him that they were done with Him.

The Darwinian walked up to God and said, "God, we've decided that we no longer need you. We're to the point that we can clone people and do many miraculous things, so why don't you just go on and get lost."

God listened very patiently and kindly to the man. After the Darwinian was done talking, God said, "Very well, how about this? Let's say we have a man-making contest." To which the Darwinian happily agreed.

God added, "Now, we're going to do this just like I did back in the old days with Adam."

The Darwinian said, "Sure, no problem" and bent down and grabbed himself a handful of dirt.

God looked at him and said, "No, no, no. You go get your own dirt!!!!"

How many atheists does it take to change a light bulb?

Two. One to actually change the bulb, and the other to videotape the job so fundamentalists won’t claim that god did it.

How do you do it?

Why are we trying to get the fox across the lake at all?

How many creatioanists x how many years will it take to figure out that evoltuion is real
