Pilgrims Trivia

Last year, I left you with some Thanksgiving trivia.  This year I think I'll post some trivia questions on the Mayflower and the Pilgrims.  Since I'll be gone until next week, the answers are posted below the questions.

1. You know about the Mayflower, but what was the name of the other ship the Pilgrims had planned on carrying then to the New World?
2.  What country did the Pilgrims leave from?
3. How many children were born on the Mayflower during the voyage?
4.  How many days did it take before the first land fall?
5.  John Carver was the first governor of the Plymouth Colony, how many terms did he serve?
6.  102 passengers set sail, 102 passengers made landing (one birth and one death).  But how many survived that first winter?
7.  What was the name of the tribe that helped the Pilgrims and later celebrated that first Thanksgiving with them?
8. Who was the captain of the Mayflower?

1. Speedwell was the name of the other ship.  After having trouble and having to turn around twice, the Pilgrims decided to travel on the Mayflower alone.
2. The Pilgrims had been living in the Netherlands but left from England on Sept 6, 1620.
3.  One, his name was Oceanus.
4.  66 days, for an average of 2 mph.
5. He was elected twice, the first time he was elected in November 1620, while aboard the Mayflower.  He was again elected in March 1621.  He died just one month later in April 1621.
6.  Only 51 survived the first winter in Plymouth.
7.  The Wampanoag tribe, which was led by Massassoit.
8.  The captain of this ship was Christopher Jones.   During that first winter, the Mayflower crew also suffered there in Plymouth, with almost half dying.  It did not leave until April 5, 1621.

There are two bars of iron. One bar is magnetized along its length, while the other is not. Using just the two bars, without any other items, how can you tell which bar is magnetized and which bar is not?

Missing Gallows

An old parchment describes the location of buried treasure:”On the island there are only two trees, A and B, and the remains of a gallows. Start at the gallows and count the steps required to walk in a straight line to tree A. At the tree turn 90 degrees to the left and then walk forward the same number of steps. At the point where you top drive a spike into the ground.

Now return to the gallows and walk in a straight line, counting your steps, to tree B. When you reach the tree, turn 90 degrees to the right and take the same number of steps forward, placing another spike at the point where you stop. Dig at the point exactly halfway between the spikes and you will find the treasure.”

However, our hero when he gets to the island finds the gallows missing. Is there any way he can still get to the treasure?

Windows out or maybe in
Never filled but too much may lessen
And sometimes to be, lost in the cold
 Whilst another finds the spice of life
But in truth.

A Time When They're Green

A time when they're green,

But just in between for a very short while,
They're perfect and yellow and cause me to smile!

His Dark Materials is good so far.  I'm thrown off by the start of the second book, though.  To start off with a whole new main character is disturbing after focusing in so much on Lyra in the first.

Prime Time Soccer

At the end of the soccer season, every player had scored a prime number of goals and the average for the eleven was also a prime number.  No player's tally was the same as anyone else's, and neither was it the same as the average.

Given that nobody had scored more than forty-five goals, how many goals did each player score?

Shepherds on Hillsides

In every group of shepherds in Hyperborea, at least one is a Sororean, who always speaks truthfully, and at least one is a Nororean, who always speaks falsely.

A visitor approached four shepherds on a hillside and asked each how many of the four were Sororeans. These answers were given:

  • Three of us are Sororeans.  
  • One of us is. 
  • There are two of us. 
  • None of us are Sororeans. 

The visitor approached four more shepherds on another hillside and asked how many were Nororeans. Their answers follow:

  • We are all Nororeans. 
  • One of us is. 
  • Three of us are. 
  • The fourth shepherd declined to speak. 

How many of the shepherds on the two hillsides were Sororeans?

David and Angela play a game of tick-tack-toe. In this game, the players try to get three circles or three crosses in a row (horizontal, vertical, or diagonal).

They follow the following rules:

A player always tries to win: if a player can place his own symbol (X or O) in a row which already contains two of his own symbols, he will do so.

A player always tries to avoid that his opponent wins: if a player can place his own symbol (X or O) in a row which already contains two of the symbols of his opponent, he will do so.

Of course, the first rule has precedence over the second rule, because the game can be won in this way.

In the game shown on the right, 6 moves have been done. David plays with crosses (X) and Angela plays with circles (0). However, we don't know who started the game.

Who will win this game?

If you're like me, you may be having trouble seeing the image of the board I tried to create. So here's a more basic image:
O | O |
O | X |
X | X |

Moon Cable

A large space agency has decided to build a base on the moon. For this purpose, a cable must be laid around the moon's equator. When the cable is laid, it turns out to be 1 meter short. In a quickly arranged meeting, it is decided to investigate the possibility to lay the whole cable in a groove.

How deep does the groove need to be to make this work?

The agency's director considers digging a groove, no matter how deep, around the entire circumference is too expensive. He suggests to lay the whole cable just a bit north of the equator. How many meters north of the moon's equator should the cable be laid to settle the problem of the lacking 1 meter of cable?

Help Win an iPad2

Hi all,
I never do this, but I'd like to make a personal appeal.  My daughter was entered into a contest to win an iPad2.  She painted a pottery piece at PYOP for her teacher at school.  The lady who runs it liked it enough to enter it into her summer contest to win an iPad2.  At six years old, that would be quite a prize.

If you have a facebook account, please head on over to the PYOP album ( and like here photo (the one with the butterfly).  In case you're wondering, it's a dunk mug.  You can put cookies down at the bottom, for dunking!

Thanks for helping out!  We'll be back to our puzzles on Monday.  Happy father's day to all the dads out there!

Ants on a Board

There are 100 ants on a board that is 1 meter long, each facing either left or right and walking at a pace of 1 meter per minute.

The board is so narrow that the ants cannot pass each other; when two ants walk into each other, they each instantly turn around and continue walking in the opposite direction. When an ant reaches the end of the board, it falls off the edge.

From the moment the ants start walking, what is the longest amount of time that could pass before all the ants have fallen off the plank? You can assume that each ant has infinitely small length.

Generous Buzz

When Buzz gathered his 2001 records for his CPA, he found that he had made six donations, each for a different amount of money and totaling $1500, to six local youth sports teams, including a softball team. Given the data below, can you find how much in sports deductions Buzz has for 2001: the contribution to each team and the sport the team plays?

  1. Buzz donated twice as much to the basketball team as he did to the Knights.
  2. The contribution to the Comets was less than that to the football team.
  3. For his donation to the soccer team, which was $50 more than he gave the Rovers, the soccer team advertised Buzz's gas station on the back of their jerseys.
  4. The Lions got $150 more from the service station operator than the baseball team did.
  5. The smallest donation of the six was for $50.
  6. The Hawks received twice as much money from Buzz as the soccer team.
  7. Before actually seeing the receipts again, Buzz thought that his largest donation had been $600 and that he had given the hockey team $250; he found that the largest contribution was for less than $600 and that the hockey donation was for less than $250.
  8. Buzz gave the Knights $50 more than he gave the Devils.
  9. The largest donation wasn't the one to the youth basketball team.

Teacher is so Smart

After studying roman numerals for a short time, the teacher had given the class some free time.  Sally's teacher walked up to her desk and saw that she had written:
XI + I = X
on her paper.

He was quick to point out her mistake.  Sally protested, saying she had it right.  After demonstrating what she meant, the teacher apologized and moved on.

What did Sally point out?

Random Walk

A drunk leaves a bar (rather forcefully).  After standing up and dusting himself off (rather unsuccessfully), he decides to walk home.  Unfortunately for him, he has no idea where home is and has no way of deciding which way to go.  He is on a street traveling east-west only, making things simpler for him.

With each step, he's just as likely to turn around and walk back in the direction he came from.  After 20 steps, how likely is it he will be back where he started from (right in front of the bar)?

Usual Suspects

Four suspects; A, B, C and D have been arrested for possibly stealing the car of the chief of police. They were all interviewed personally by the chief, and were hooked up to the lie detector.

Each suspect gave three statements during the examinations, that are listed below:
Suspect A:
In high-school I was in the same class as suspect C.
Suspect B has no driving license.
The thief didn't know that it was the car of the chief of police.

Suspect B:
Suspect C is the guilty one.
Suspect A is not guilty.
I never sat behind the wheel of a car.

Suspect C:
I never met suspect A until today.
Suspect B is innocent.
Suspect D is the guilty one.

Suspect D:
Suspect C is innocent.
I didn't do it.
Suspect A is the guilty one.

Unfortunately, there was a lightning strike and the machine went haywire. After the recovery process, the machine only reported that exactly four of the twelve statements were true, but not which ones. And now all four suspects have gotten lawyers and are refusing to be re-interviewed.

Can you figure out which suspect did it?

Socks Again

So, here you are, packing your socks up again in the dark. You would think you would have learned your lesson from the whole 'cat incident', but no. You still have 2 red, 4 yellow, 6 purple, 8 brown, 10 white, 12 green, 14 black, 16 blue, 18 grey, and 20 orange socks (see yesterdays post on sock packing). But on your last trip you were embarrassed to find you had ended up packing three pairs of orange socks. You certainly stood out in that crowd. And when your boss asked you on the third day if you even bothered to change your socks... well!

This time, you want to guarantee you have three different pairs, to make it clear, without having to say so, that yes... you do indeed change your socks once a day.

So how many socks do you have to pull out before you know for sure you have three different colored pairs?

In your bedroom you have a drawer with 2 red, 4 yellow, 6 purple, 8 brown, 10 white, 12 green, 14 black, 16 blue, 18 grey, and 20 orange socks. The socks are all jumbled together in the drawer. It is dark in your bedroom, your partner is still asleep and so you don't want to turn on the light to see. So you cannot see which sock is which in the dark.

You are packing for a trip that will take you three days, so you need three pairs of socks.

How many socks do you need to take out to be sure that you have at least three pairs of socks of the same color?

Lucky Or Not

The Card Sharp on the BoulevardImage by cliff1066™ via Flickr

You are a card shark, thrown in jail after you were caught dealing from the bottom of a deck. The sheriff, who has a reputation for being honest, has told you the swinging judge is on his way to town for the trial. You plead for him to let you out promising never to return to his territory again.

He says, "Sure, but let's see how lucky you truly are."

He shows you a special deck with 23 cards in it. One side of each cards has an X, while the other side has on O. He throws the cards behind you (you cannot turn around and look, yet). He tells you 14 of them have landed with the X side up (which means the other nine landed with the O up).

He pushes you into the cell and closes the door, leaving you without any light at all. Calling through the door, he sets the challenge. "Put the cards into two stacks, so that both stacks have the same number of X's facing up! I'll be back in one hour."

You can hear him laughing as he walks away.

You spend the next 55 minutes gathering the cards together. One had fallen behind the cot's leg, making it especially hard to find in the dark. You made sure not to flip any of them over so that there are still 14 cards with the X side up, assuming the sheriff wasn't lying to you about that.

You have five minutes left to meet the challenge. What do you do?

Can You Trust the Delivery Guy

Stylized crime.Image via Wikipedia
An undercover cop was shocked by what he had overheard. The gang he had infiltrated was planning on murdering his old partner Jake. He knew the gang had bribed someone else at the police dept, but he didn't know who. He had to get a message out to his partner so they could meet.

Quickly, he wrote out a message and got it delivered. Since he didn't know who to trust at the department, it was in code.

At the dept, Jake opened up the letter and read: "Flame mate weighty soak shave. comedy debut stake scared.", glanced at the clock on the wall and realized he still had time to make the meet.

How did Jake know when and where to meet?

In My Opinion, This is Hard to Do

This is a famous problem from 1882, to which a prize of $1000 was awarded for the best solution. The task is to arrange the seven numbers 4, 5, 6, 7, 8, 9, and 0, and eight dots in such a way that an addition approximates the number 82 as close as possible. Each of the numbers can be used only once. The dots can be used in two ways: as decimal point and as symbol for a recurring decimal. For example, the fraction 1/3 can be written as
. 3

The dot on top of the three denotes that this number is repeated infinitely. If a group of numbers needs to be repeated, two dots are used: one to denote the beginning of the recurring part and one to denote the end of it. For example, the fraction 1/7 can be written as
  .               .
. 1 4 2 8 5 7

Note that '0.5' is written as '.5'.

How close can you get to the number 82?

Twice the Fun at Half the Price

Someone shows you two boxes and he tells you that one of these boxes contains two times as much as the other one, but he does not tell you which one this is. He lets you choose one of these boxes, and opens it. It turns out to be filled with $10. Now he gives you the opportunity to choose the other box instead of the current one (and give back the $10 from the first box), because the second box could contain twice as much (i.e. $20).

The Question: Should you choose the second box, or should you stick to your first choice to maximize the expected amount of money?

Lady or the Tiger

The king explained to the prisoner that in Room 1, if a lady is in it, then the sign on the door is true. But if a tiger is in it, the sign is false. In the Room II, the situation is the opposite: a lady in the room means the sign on the door is false, and a tiger in the room means the sign is true. It is possible that both rooms contain ladies or both rooms contain tigers, or that one room contains a lady and the other a tiger.

Room 1 Sign: Both rooms contain ladies
Room 2 Sign: Both rooms contain ladies

Pointing to the signs, the king asked the prisoner which room did he wish to choose?

Biggest Loser

In the most recent Biggest Loser competition, the contestants had to arrange the order of five dishes from least calories to most.  If they did it blind-folded, how many different ways could the food be arranged?

But let's say they have some knowledge about a couple of the dishes.  They know the plate of hamburger (loaded with everything) and chips should be near the top, while the plate of broccoli should be near the bottom of the scale.  How does that affect the number of choices?

Another Carroll Riddle

'First, the fish must be caught.'
That is easy: a baby, I think, could have
caught it.
'Next, the fish must be bought.' That is easy: a penny, I think, would have
bought it.

'Now cook me the fish!'
That is easy, and will not take more than a minute.
'Let it lie in a dish!'
That is easy, because it already is in it.

'Bring it here! Let me sup!'
It is easy to set such a dish on the table.
'Take the dish-cover up!'
Ah, that is so hard that I fear I'm unable!

For it holds like glue-
Holds the lid to the dish, while it lies in the
Which is easiest to do,
Un-dish-cover the fish, or dishcover the

Lewis Carroll Box

John gave his brother James a box:
About it there were many locks.
James woke and said it gave him pain;
So gave it back to John again.
The box was not with lid supplied
Yet caused two lids to open wide:
And all these locks had never a key
What kind of box, then, could it be?

Back in School Counting

Students of Nan Hua High School gathering in t...Image via Wikipedia
Of 28 students taking at least one subject, the number taking Math and English but not History equals the number taking Math but not History or English. No student takes English only or History only, and six students take Math and History but not English. The number taking English and History but not Math is 5 times the number taking all three subjects.

If the number taking all three subjects is even and non-zero, how many are taking English and Math but not History?

River Crossing

I have posted more complicated crossing problems before, but with another six inches of snow to shovel outside, this seems good enough to me.

A dad and two sons needed to cross the river.  They have a canoe and paddles, but no other equipment.  The canoe has a weight limit of 150 lbs.  Luckily, dad weighs 150 lbs.  The two sons weigh 75 lbs each.  How can the all get across the river using the canoe?

Snowed In

WELLS, UNITED KINGDOM - DECEMBER 20:  A snow p...Image by Getty Images via @daylife
It snowed last night! Four couples woke up to a winter wonderland this morning. Due to the high winds during the storm, the snow drifted as it fell. The plows were out early but still, it took awhile to get all the streets in town cleared. Determine the full name of each couple, how much snow they got form the storm (between 6 and 10 inches), and what time the road they lived on was plowed out (between 8:30 am and 10:00 am).

1. Rebecca, whose last name isn’t Heart, was plowed out before Greg but after the couple who got eight inches of snow.

2. Mr. and Mrs. Shephard have two inches more snow than the couple who were plowed out at 8:30 am.

3. Karl and Debbie weren’t plowed out at 9:00 am though they were plowed out before Peter.

4. Stan Grant, who isn’t married to Martha, got one inch more snow than Greg did.

5. The couples were plowed out, from earliest to latest, in the following order: the couple who got eight inches of snow, Alice, Peter, Mr. and Mrs. White.

Rebus are puzzles you need to solve by looking at the words, their relationships to each others and trying to imagine how it represents a common phrase.

For instance,  BIRD can mean Big bird or pa per can mean paper cut.

During the recent Fast Track Cup, the first four horses did well to finish ahead of the field. After Dinner was not last and the horse wearing blue was not third. Bitter Twist was before the horse in green. Dare Devil came first. Bitter Twist finished before After Dinner. Catch Me wore red but Bitter Twist did not wear yellow.

Can you determine where each horse finished and the colours they wore?

Corn Can Be Fractionalized

Ahmes's Papyrus
About 1650 B. C., Egyptian scribe Ahmes, made a transcript of even more ancient mathematical scriptures dating to the reign of the Pharaoh Amenemhat III. In 1858 Scottish antiquarian, Henry Rhind came into possession of Ahmes's papyrus. The papyrus is a scroll 33 cm wide and about 5.25 m long filled with funny math riddles. One of the problems is as follows:

100 measures of corn must be divided among 5 workers, so that the second worker gets as many measures more than the first worker, as the third gets more than the second, as the fourth gets more than the third, and as the fifth gets more than the fourth. The first two workers shall get seven times less measures of corn than the three others.

How many measures of corn shall each worker get? (You can have fractional measures of corn.)

May Not See it For a While

I am around long before dawn.
But by lunch I am usually gone.
You can see me summer, fall, and spring.
I like to get on everything.
But when winter winds start to blow;
Burr, then it's time for me to go!
What am I?

Oh, and Happy New Year everyone!
