It was in the Kasbah of Casablanca. Mohammed, the guide, led Jack and Jill up some narrow staircases into a large hall full of colorful carpets with intricate designs hung up on the walls, placed around on the floor, with smaller ones in piles here and there.

Jill took some photos, Mohammed vanished.

“Please sit down and enjoy a cup of tea,” said Abu Hamza, the manager of the shop.

Jack and Jill were served mint tea in tiny glass cups placed on a small decoratively carved wooden octagonal table by a servant wearing a djellaba, introduced as Mustafa.

A long discourse by Abu Hamza ensued, with carpet after carpet from large to small in sizewise descending order being presented by Abu Hamza.

Mustafa would dutifully carry each carpet and place it on the floor in front of Jack and Jill so they could inspect and admire it, while Abu Hamza detailed its history and how many years it took one or several dedicated women to make it.

The carpets started at 5,000 dollars, dropping in price until Jack and Jill decided on a small carpet, so as not to offend Abu Hamza – after such a fine presentation of Moroccan carpets being placed and neatly folded before them by Mustafa.

“We accept all credit cards, shipping anywhere in the world,” said Abu Hamza proudly.

“We’ll take that one for 150 dollars, in cash,” said Jack, Jill nodding her head vigorously with a silly smile.

“Inshallah, as you wish,” bowed Abu Hamza.

“As a special token to you, our honored, cash-paying guests, if you can work out a riddle, I will give you a superb 200 dollar carpet that it took Habiba two years to make,” offered Abu Hamza.

“We will gladly listen to your riddle,” said Jack, pulling out a notebook and pen.

“This is the riddle: Once, there were five Moroccans who had a total of 200 carpets. Previously one of them had had 12 times as many carpets, another had had three times as many, still another had had the same, yet another had had half and even another had had a third as many – at both times all carpets totaling 200. How many carpets did each of the Moroccans have previously and later?” said Abu Hamza with an enigmatic smile.

“We get the idea, Abu Hamza,” said Jack, having taken some notes. Jill pulled out a calculator.

“I’ll give you ten minutes to think about the answer to this riddle,” said Abu Hamza. “Please enjoy some more Moroccan tea.”

Jack and Jill worked out an answer to the riddle by trial and error, and were happy to be able to walk out of the shop with a neatly folded carpet under Jack’s arm.

Mohammed, the guide, suddenly appeared again to lead them to a ‘very interesting’ silver jewelry shop.

Can you work out the answer to Abu Hamza’s riddle?

Sheik Abdullah ben Suleiman al Rashid was assassinated, leaving a will that only included his three sons. The will stipulated that his 35 camels be divided into 2, 3 and 9 parts among them.

The Sheik’s sons Mohammed, Barkatullah and Fawaz waxed hysterical in trying to work out what to do to comply with their father’s will.

“How can we divide a camel into two or three or even nine parts?” said Mohammed pulling anxiously on his beard.

“It is definitely not possible,” responded Barkatullah, puffing heavily on his hookah, eyes rolling.

“Perhaps we should consult the butcher so we can all get a fair share according to our father’s will,” suggested Fawaz, sipping his black coffee while Fatima adjusted his caftan.

They discussed the matter loudly for hours until their neighbor Mahmoud al Mansur got fed up with the noise disturbing his prayers. Mahmoud went to see them and suggested that the problem could easily be solved, explaining what needed to be done.

As the solution was so simple, Mohammed, Barkatullah and Fawaz quickly agreed and the division of the camels went smoothly.

“With an inheritance of 53 camels, I would have had a profit of two camels in the deal instead of one,” lamented Mahmoud al Mansur, leading the two camels to his stables.

How did Mahmoud al Mansur solve the problem of dividing Sheik Abdullah ben Suleiman al Rashid’s camels among Mohammed, Barkatullah and Fawaz, and why would he have gained two camels if there had been 53 camels in the will?

It was 10 pm in the midwestern town of Dry Gulch, and the last show at the Roxy theater had just ended with all moviegoers gone home.

“Hey Molly, how many people attended the last movie ’Dead Man’s Canyon,’ starring John Waylon and Mary Pineworthy,” shouted the theater manager Barney Mudd through the door of the ticket office.

“No idea, Barney. I just sell tickets around here,” replied mop-haired Molly as she wiggled her plump body out of the armchair, getting ready to go home.

“The boss is on the phone and wants to know, Molly,” insisted Barney Mudd. “So you’d better figure it out quick, chop-chop.”

“Look Barney, I sold ticket to adults for $3.60 and for $1.50 to kids tonight. The take was $540 and there weren’t many kids. You go figure it out, Barney,” said Molly as she locked the door and left for home.

Barney Mudd remained standing at the Roxy theater’s entrance with a bewildered expression on his face, watching Molly waddle home. Then he rushed off to call his son Leonhard, who was good at math.

Can you help Barney Mudd and Leonhard work out how many adults and children attended the movie show that evening so he can tell his boss and go home to his wife Mildred?

The host of the show, Barnstorm McDoodle, stood on an elevated podium studded with multi-colored lights. Barnstorm was wearing a jacket splattered with bright small reflectors, flashing a wide Hollywood smile under a pencil thin moustache – his thick, abundant black hair extending backwards like freshly plowed furrows in a field.

A large, transparent plastic globe full of thousands of small colored plastic balls stood in the middle of the floor between Barnstorm McDoodle and the opposing consoles of team A and B. From the globe a tube led into a small tray.

“Tonight, the contestants – Jack and Jill on my left, Mabel and Seymour on my right – can win a lot of money by guessing how many balls there are in this large globe,” announced an animated Barnstorm McDoodle, waving his arms regally to contestants and audience.

“But…if they fail…they win nothing, and the pot will be doubled for next week’s contestants,” added Barnstorm McDoodle.

“To investigate the contents of the globe, the contestants will enter numbers at their panel, to be repeated on this large screen. The number will divide all the balls in the globe into equal groups, ungrouped balls rolling out from the globe through this tube into the tray – which balls my lovely assistant Jane will fetch and replace in the globe.”

“The first team to correctly state how many balls the globe contains will win an amount in dollars equal to the number of balls,” proclaimed Barnstorm McDoodle.

“Any team can request a five minute break to work out a guess, but if it’s wrong they’ll be disqualified, so let’s get on with the show,” shouted Barnstorm McDoodle.

“But first a word from our sponsor, Ace Dogfoods.”

After Ace Dogfoods’ prolonged message, Jack and Jill entered “2” at their panel, which then appeared on the large screen. One ball rolled out into the tray and Jane stepped forth briskly on long legs to put the ball back into the globe.

“Write it all down, Jill,” said Jack.

Mabel and Seymour entered “5” and four balls rolled out into the tray, rapidly picked up and replaced by a smiling Jane.

Jack and Jill entered “6” and five balls rolled  out into the tray, Jane wiggling into action again.

“I see where this is going,” said Jack. “Let’s find a zero.”

Then, Mabel and Seymour entered an “8,” which resulted in seven balls in the tray, recovered in lithe strides by Jane.

Jack and Jill decided to take a chance and entered “11” at the panel. This time no balls came out of the globe.

“Yes!!! We request a break,” said Jack quickly, pulled out his calculator, a pen and notepad.

“Ok, folks, let’s see if Jack and Jill can guess the right number while we hear a word from our sponsor, Ace Dogfoods,” said Barnstorm McDoodle cheerfully.

“Come on Jill, use what you learned in the number theory course to figure this out rapidly before Mabel and Seymour do,” said Jack urgently. “I want to buy that motorcycle.”

“Ok, Jack, I think I see the pattern,” said Jill with a dimpled smile. “Write down what I say and get your calculator ready to win the Caribbean cruise I want.”

At the end of the five-minute word from Ace Dogfoods, Jack announced the result Jill had worked out – which, happily, turned out to be the correct number of balls in the globe.

“People, we have a winner for xxxxx dollars,” shouted Barnstorm McDoodle jubilantly, giving Jane a big hug.

What would you say was the least possible number of balls in the large globe?

Fred and Mary were trying to work out how to give five gifts to their three boys for Christmas.

The kids, Henry, Mark and Joe, had told them they wanted to receive gifts more or less at random this year to see how the gifts would be distributed.

“We have five gifts to give to three children. How are we going to do this, Mary? There are so many possibilities it makes my brain spin,” said Fred in exasperation.

“Well, Fred, we have to make sure they all get at least one gift, so that makes it easier than the way you are thinking of, doesn’t it,” Mary said reassuringly.

“You’re right, Mary. The number of ways of giving the gifts so that our kids might not receive even one gift is quite large,” said Fred.

“Do it my way and the matter becomes more simple,” said Mary.

So Mary and Fred distributed the gifts as she suggested.

If they distributed the gifts Fred’s way what would be the probability that one or more of the kids received no gift?

A crew of pirates robbed a Spanish galleon off the coast of Crooked Island. Among the booty they found a chest full of gold coins.

The captain was killed during the battle, so to ensure a fair share the crew decided to immediately divide up the gold coins on a nearby uninhabited island before a new captain was chosen.

The 17 surviving pirates began distributing the coins into 17 piles on the beach, but three coins were left over. No agreement could be reached as to who would get the three coins, and, after a large amount of rum was consumed, fighting followed in which one of the pirates was killed.

The pirates then divided up the coins into new piles, but, alas, this time there were as much as ten coins left. With further violent discussions, more rum and fighting another pirate was killed.

The remaining crew set about to divide the gold coins of the chest into equal piles and this time they succeeded in obtaining an equal distribution, which, after opening another barrel of rum, they celebrated until they were spread about on the beach in a drunken stupor.

It turns out they had been observed by a small Dutch crew which had been marooned on the island after a terrible storm. This crew carried away the booty and sailed off while the pirates were sleeping off the rum.

Can you work out what the least number of gold coins in the treasure chest was?

Jerry and Slick were sitting at a bar drinking beer and watching a championship football game being televised on the huge wall screen, a bowl of peanuts close at hand.

“Hey Jerry, want to play a game?” said Slick, taking a large sip of his cold beer.

“Sure, what’s it all about,” replied Jerry, munching on some peanuts while eyeing the curvy waitress.

“It’s really simple. I throw this die and if you throw a higher number, you win one point, otherwise I get the point,” explained Slick as he placed a large red die between the beer glasses on the green felt-covered bar counter.

“Let’s try it first, Slick,” said Jerry with a suspicious look.

Slick threw the red die and got a two. Then Jerry threw and got a three.

“Hmm, seems like a good game,” said Jerry with a sly smile.

“Glad you like it, Jerry. How about we play twenty rounds, or until the football game is over – point loser pays the bill?” said Slick.

“Fine by me,” replied Jerry, giving a loud cheer for a goal just made and snatching a handful of peanuts from the bowl.

Slick ordered some fast food and they rolled the die until the end of the football game.

Who do you figure paid the bill, and why?

Jack asked Fred “How old are your family members?”

“Ten years ago my father was twice my age and my mother’s age was a perfect number,” said Fred.

“That helps with your mother’s age, but I need more information about your father,” said Jack.

“No problem. The square of my father’s age is equal to the year he was born,” replied Fred.

“Ok, got it,” said Jack. “What about your brother and sister?”

“Ten years ago my sister Lara was the same age as my brother Nick is now. In two years my father will be half the age his father was when he died,” said Fred.

“Very interesting,” said Jack.

“My great grandfather told my father he would be reborn in a year equal to one quarter of a perfect number, which is when Nick’s turtle – that my great grandfather gave to my father newly hatched ten years before he died – will probably die,” said Fred.

“How nice, any more info?” said Jack.

“My sister Lara’s age is a divisor of the cross sum of the turtle’s present age,” said Fred.

“And what about your grandfather’s age?” asked Jack.

“When my father was born my grandfather was as old as half the sum of my mother’s age and that of my father’s ten years ago,” said Fred.

“Gee thanks, I’ll go and think about it,” said Jack and walked off.

What do you say are the ages of these family members, including the turtle.

The generals Chi Wong and Chow Loo were having a discussion one day on the top of a hill overlooking the plains of their respective army camps.

“My army is bigger than yours,” said general Chi Wong to general Chow Loo. “I’ll wager my best concubine on it.”

“Wager likewise accepted,” said general Chow Loo. The generals decided to verify the facts of the matter and called in their major generals Soo Flick and Boo Mung to settle the issue.

“Soo Flick, arrange my army in a square below on the plain so you can more easily determine the number of men in my army,” commanded General Chi Wong.

Major general Soo Flick ran off to comply with the order, and major general Boo Mung ran off to carry out the same command issued by general Chow Loo.

The following day the armies were arrayed in square formation on the plain below and major generals Soo Flick and Boo Mung returned to report the result.

“Honorable generals Chi Wong and Chow Loo, we have determined that general Chow Loo has 3,011 more men than there are in general Chi Wong’s army,” reported major generals Soo Flick and Boo Mung.

“What a surprise! But I’ll win Li Mai back on the next bet,” said general Chi Wong confidently.

Can you work out how many men there were in the armies of the generals?

Albert Jones went to cash a check in a bank. The bank teller, named Bonzo Sludge, had just smoked some weed and his mental faculties were distorted leading him to wrongly read the amount written on the check, the numbers swimming around in his head and forming an amount in reverse order.

Bonzo Sludge paid Albert Jones the erroneous amount with a silly, cross-eyed grin on his face and continued playing his video game on the computer at the teller station.

After receiving the money, Albert Jones checked the amount paid out to him and noticed that money was missing and that the missing amount was a square number.

Albert Jones returned to resolve the error with bank teller Bonzo Sludge, but after receiving a vacuous, bovine and uncomprehending look Albert Jones decided to head for the bank manager’s office, where he received the missing amount of money and assurances the personnel glitch would be remedied.

Can you work out what the missing amount was?
