Yeah, I'm more inclined to say 54.

I'm thinking thusly too.

Quite so, one could think of several ways of doing it. But the answer he gave was the simplest.

Put a rowboat in water (a lake or a pond). Put the elephant in the boat and mark the level to which the boat sinks. Then remove the elephant from the boat and fill the boat with gold coins so that it sinks to the same mark in the water.

Indeed. Due to some reason they have the rule of 4 characters minimum.

Quote:

If a hen and a half lays an egg and a half in a day and a half, how many eggs can 9 hens lay in 9 days?

This again can be worked out with simple arithmetic.

1½ hens lay 1½ eggs in 1½ days. So in 9 days, they will lay 9/1.5 X 1.5 or 9 eggs.

So we have 1 ½ hens laying 9 eggs in 9 days. So 9 hens will lay 9/1.5 X 9 = 54 eggs in 9 days.

And what is wrong with an edit if one discovers an error? I edit my posts many times. Sometimes it is just spelling errors, sometimes I like to add something, sometimes I can think of a better way of saying something (after I have posted it). Edit feature is there to be used, what is wrong with that?

Here's one of my favourites, which in my experience people either get immediately or never get at all. If a hen and a half lays an egg and a half in a day and a half, how many eggs can 9 hens lay in 9 days?

[Hint: it's not 81]

Anyone feel up to discussing the old Monty Hall problem again?

Off the top - 54

How does one put an elephant in a row boat? Row boats weight 150 lbs. max, an elephant weighs about 6 tons. What do you think would happen as soon as the elephant puts one foot in the boat?

Right. I find this a simpler way to think about it though: As the problem is stated, it takes one hen a day and a half to lay an egg, so in 9 days she'll lay 6, and 9 hens will lay 54.

Oh, stop being such a pompous twit. I was going to comment on your reply, but it changed while I was replying to it. I wasn't being critical, you need to relax a little bit.

If you're going to be so fussy about editing your posts, maybe you can let us know how you can divide 8 dinars by giving one person 8, and the other 1.

I figured you had 6 times as many hens, for 6 times as many days...and then remembered that the original productivity was 1.5...

Quote has been trimmed, See full post:
I figured it would easier to take a log, and place a stout plank on it, heavy enough to support the elephant, then you've got a simple balance beam. If you ahve access to a rowboat big enough for an elephant, you probably have access to some timber.

The easiest and most sensible way is to take a collapsable canvas tub about 16' diameter and 12' high and get the elephant to step onto it, then you raise the sides and fill it with water. YOu know before hand what the capacity is empty, so you just have to measure the with the elephant stand in it. Figure out the cubic footage the elephant displaces and divide by 19 the specific gravity of gold and that is the vol. of gold you pay the guy. You have to be fast so you don't drown the elephant.

Or better still drown the elephant first.

You have to make sure you've got the elephant floating, though.

One costs \$1, ten cost \$2, 100 cost \$3, 1000 cost \$4. What are they?

At the end of the meal, the stranger thanked them, gave them 8 dinars and left. Now the two friends had an argument. Friend A said that he should get 5 dinars and B should get 3, since he contributed five loaves his friend contributed only 3. Friend B said that since they are friends, it is only fair that they split it evenly four each.

So, what is the fairest way of splitting the eight dinars? Hint: they are both wrong.

Missed that the first time thank you - But I stand by my logic as well - Only one Christian country uses dinars - Serbia - Also Muslim as well as many other cultures would prohibit the acceptance of monies as a guest was invited to share a meal.

Agreed, I'd be pretty insulted if a guest at my table offered payment for the meal, or expected it from me as a guest. But for the purposes of the puzzle we're expected to put aside reality for a moment...

I guess it would have simplified things considerably if he'd have just stated "units of local legal tender". Or "ullt"s.

I agree the person that poses the question makes the final ruling - Unless of course Judge Goober - the nicest Judge in Alberta - is called upon - then others may also be called upon - then the begats beging and before you know we even may agree -

Guess we will have to get into the Vulcan mode.

7 men going from church are outside when it starts to pour rain - 6 men immediately run for cover and get wet - the other man stayed where he was and remained completely dry. Why????

1st Hint - One word in this changed to the plural usage will provide a clear hint.

2nd Hint - The same word in French sounds quite similiar to the English version - and would be easily understood by many English speakers and the Latin would also be understood by English and or French speakers. Not all but by a substantial number.

Still puzzling over JLM's post #101 from 3 days ago: "One costs \$1, ten cost \$2, 100 cost \$3, 1000 cost \$4. What are they?" Nobody's attempted a response yet, so I presume everybody's either forgotten it or is in the same state I am: completely mystified and obviously missing something. Do 10,000 cost \$5? I note that the cost in dollars equals the number of digits in the number...

HA! A stroke of insight! You're buying digits for a house number, an address., \$1 per digit. 1 to 9 is one digit, costs a dollar, 10 to 99 is two digits, costs \$2, etc.

I'm just way too pleased with myself over figuring that out. Here's another one I like.

A saintly young girl goes into a church carrying a bouquet of roses. She leaves some of them in the church, and when she exits the building, the number she's still carrying is magically doubled. That's how saintly she is. She goes into a second church and leaves the same number of roses, and the same thing happens when she leaves. She goes into a third church and leaves the same number of roses again, and exits carrying a single rose. So how many was she carrying initially and how many did she leave in each church?

Hint: the number of solutions is mathematically infinite, so keep it to the minimum number she could actually carry. And for bonus points, what's the relationship between the number she starts out with and the number she leaves?
