You have a farm a need to buy three sorts of animals

Horse cost 10 dollar
Goat cost 2.5 dollar
chicken cost 0.10 dollar

Normally you have 100 dollar and nee d to buy 100 animals total, but here is the twist, it is possible to solve the puzzle for x dollar and x animals, but what is the minimal whole number of dollars for x to solve this puzzle?

zero (probably not what you're looking for)

If you don't have to buy at least one of each type of animal, then you can buy 3 goats and 5 chickens for $8.

But you do need to buy atleast one of each.

I well Try, Thanks.

If 13 is the minimum answer you need to buy 13 animals for $13

Well, in that case...
1 horse, 3 goats, and 15 chickens for a total of 19 animals.

[size=8]AABBCCDDEE
(a) 9!/(2!)^4
or 22680
(b) 10!/(2!)^5 - (a)
or 9!/(2!)^4 * 8/2!
or 90720
(c) C(7,2) * 4!/(2!)^2 * 6!/(2!)^2
or 11340[/size]

That's right Mark. I wonder how many possible solutions this puzzle has without the constraint minimum, but with a maximum of 100 animals for $100


19 animals for $19

100 animals for $100

Each horse requires ten chickens to average $1 per animal.
Three goats require five chickens to average $1 per animal.

Therefore, I suspect all solutions are of the form:
11x + 8y
where x and y are positive integers.

Mark:


AABBCCDDEE
(a) 9!/(2!)^4
or 22680

(b) 10!/(2!)^5 - (a)
or 9!/(2!)^4 * 8/2!
or 90720

(c) C(7,2) * 4!/(2!)^2 * 6!/(2!)^2
or 11340

Is he great or what!



Shari and Pamela are among 10 different women standing in line to enter a theatre. There are exactly 2 people between Shari and Pamela. In how many ways can such a line-up occur


Generalize your solution to the problem above for Shari and Pamela being among n different women standing in line to enter a theatre, with exactly k people between Shari and Pamela

Mark:

THEATRE LINE
564,480
2*(n-k-1)*(n-2)!

Or as I saw it 2 * 7 * 8! (same difference)
Shari (S) and Pamela (P), together with the two people between them, make up a fixed unit. With the four people fixed through this requirement, there are six others to account for, or a total of 7 "spots" in the line-up.

First, choose one of the seven spots for the 4-person unit. This can be done in 7 ways. Now, using the six other spots and the two between S and P, permute the 8 other people into these 8 spots. This can be done in 8! ways. Finally, recognize that P and S could change places, thus there are two ways for S and P to arrange each other within the four-person unit. If you don't believe me, just ask Mark.

Alive without breath,
As cold as death;
Never thirsty, ever drinking,
All in mail never clinking.


This thing all things devours:
Birds, beasts, trees, flowers;
Gnaws iron, bites steel;
Grinds hard stones to meal;
Slays king, ruins town
And beats high mountain down.



Thirty white horses on a red hill,
First they champ,
Then they stamp,
Then they stand still.



No legs lay on one-leg, two-legs sat near on three-legs, four legs got some.


A box without hinges, key, or lid,
Yet golden treasure inside is hid.

A group of campers have been on vacation so long, that they have forgotten the day of the week. The following conversation ensues.

Darryl: What's the day? I don't think it is Thursday, Friday or Saturday.
Tracy: Well that doesn't narrow it down much. Yesterday was Sunday.
Melissa: Yesterday wasn't Sunday, tomorrow is Sunday.
Ben: The day after tomorrow is Saturday.
Adrienne: The day before yesterday was Thursday.
Susie: Tomorrow is Saturday.
David: I know that the day after tomorrow is not Friday.

If only one person's statement is true, what day of the week is it

What is the missing number and why?
