GAME: Brain Teasers

Post by **UBT - Chris** » Sat Dec 13, 2014 1:13 pm

This thread is for brain teasers - if you have a QUESTION for answering, put Q1, Q2, etc. (in order), and if you are answering a question, put A1, A2,etc (again, in order).

E.g:

Q1: how many apples does jack have if he has 4 apples less than joe, who has 2x more than albert, who has 8?

A1: 12 apples.

This process gets repeated.
Each Q can only be answered once, but if it is incorrect, somebody else may answer it.

I'll start...

Q1: Some months have 30 days, some months have 31 days. How many have 28 days?

A fun idea Chris, I totally failed on question 1 though.

So now let me ruin it for everyone with this, one of my favourite little maths teasers.

Q6. I drive my old Ford Focus around a mile long race circuit and finish the lap with an average speed of 30mph, I decide to do another lap of the same circuit, but how fast do I need to go on this second lap if I want to complete both laps at an average speed of 60mph? :scratch:

Post by **UBT - Chris** » Sun Dec 14, 2014 9:39 am

correct on both, rich and i like the question, mark

Post by **UBT - Chris** » Sun Dec 14, 2014 9:44 am

A6: Not entirely sure, but I'm gonna go with 90mph.

This is annoying me! I thought it was 90 MPH but I'm sure it's not that easy - I'll get it...

Post by **UBT - Mikee** » Sun Dec 14, 2014 11:44 am

Steady on I'm still trying Josh's!

A6

My head hurted thinking about this one - right I've got it, it's defo not 90. It's such a sneaky question I'm not going to spoil it by giving the answer obviously.

Hopefully this is white on white! It's impossible as you've all ready taken 2 minutes to do the first mile, to average 60MPH over 2 miles you'd need to do both laps in 2 minutes, as you've all ready taken 2 minutes to do the first you'd have to do the second instantly!

Post by **UBT - Mikee** » Sun Dec 14, 2014 12:19 pm

Tim - can we move this thread to the Team Cafe section?

I think we need to have a couple of rules for this.

1 - Quote original question in the answer - otherwise it's gonna get confusing when other members post questions before others are answered.

2 - Don't post your answers too quickly - we need to give other people a chance to answer and make their brain hurt! So something like allow 6 hours before answers are given even if they're wrong!

or

if you have to give an answer you could post your reply as white text on a white background?

Mike

Post by **UBT - Chris** » Sun Dec 14, 2014 12:25 pm

that's why I wasn't too sure - it could be 120, maybe, but it is logical for it to be 90: 30mph+90mph = 120mph/2 = 60 = avg...

A6. Lightspeed!

A 1 mile track done once at 30mph average speed takes 2 minutes.
A 1 mile track done twice at 60mph average speed takes 2 minutes.

No more time left after the first run

A8. The chain is anchored between the horse and the apple

Or ... the other end of the chain isn't fastened to anything

For the mathematicians among us:

Q9. Find the mistake:

A = B
A*B = B*B
A*A - A*B = A*A - B*B
A(A-B) = (A+B)*(A-B)
A = A+B
BUT, A=B therefore A = 2A and 1=2!

Well done Mark, and well done to Mike who I think had worked it out too.

Most people answer 90mph, but as Mark showed, you have to think in terms of the time taken for each lap.

Since A = B , (A-B) = 0 therefore the line A(A-B) = (A+B)*(A-B) is actually A*0 = (A+B)*0 and anything multiplied by zero is zero, so eliminating the zero from both sides of the equation has no mathematical meaning.

A classic:

Q11 A farmer has a bag of corn, a hen and a sheepdog to transport across the river.

His boat can only carry him and one other item at a time.

The sheepdog will eat the hen if left alone with it, the hen will eat the corn if left alone with it, the corn is vegetarian and won't eat either of the others

How does he get them all across the river successfully?

(To save the smart alec answers, the river is too wide to throw things across, neither the dog nor hen can swim and the bag of corn sinks

)

Well I'm guessing that either the dog is called 'who is on the opposite side of the river'

, or the river is frozen over and the dog just walked across the ice.

There's a barely perceptible 'bend' in the slope of triangle A which 'straightens' out on triangle B. The difference is exactly 1 square.

A23 - if you recall your trig from school, then you'll remember that the angle of a triangle can be calculated by opposite divided by adjacent....

In both triangles, the angle to the vertical in red section is 2/5 (=21.8014 degrees) and for the blue section it's 3/8 (=20.556 degrees). So for Triangle A, the long hypotenuse bows out at the left and then cuts inwards on the right, and for triangle B, the opposite occurs. So, it's an optical illusion that the hypotenuse's are both perfectly straight

Q27: Extra Special Bonus Xmas Question:

You can have until Boxing Day to answer it

If no correct answers by then, I get a point.

It was good to have the house full of people again; it had been far too quiet since the last of his seven daughters had left for college--seven daughters with seven different majors at seven different schools. About the only thing they had in common was that they were each dating an athlete, although none of them played the same sport--one was even on his school's fencing team. He was surprised all the boyfriends had come for Christmas dinner, but he supposed that since he was picking up the tab for the airfare, that a free trip to Hawaii in the winter had something to do with it. Each of his first three daughters had gone to Ivy League schools--one even to his alma mater at Harvard; his next two ended up at the University of California, at Los Angeles and Berkeley; and his two youngest got accepted to schools abroad--the University of Tokyo had been a bit of a surprise. Next year, after seven straight years--and for the first time this millennium--he wouldn't be attending a high-school graduation.

"Honey, we're ready to eat. Can you get Hank, Ian, James and Kyle? They're in the backyard playing football. The other boys wanted to test themselves against the star quarterback," his wife called from the dining room.

The math major said, "I'll get them Dad!"

As everyone filed into the dining room, the oldest sister was rehashing the whose-school-and-major-is-better argument with her younger sister about whether Yale or Princeton was a better school and whether history or philosophy was a more useful major. The argument was practically a Christmas tradition by now.

The table was arranged with the parents at the two ends and each of the couples seated across from each other with boys seated next to girls along each side. As usual, Angelina and Danica were sitting next to their parents. Curiously, all the athletes that used a ball in their sport were sitting on the same side of the table. Christie, Electra and Edward took their seats first.

Once everyone was seated the youngest coyly observed, "I see the biologist is sitting between the two fighters but I'm sitting between the two best passers at the table."

"You'd better not make any passes yourself!" Farrah icily replied. She hadn't forgiven her sister for stealing her boyfriend when they were in high school and was not happy to see her seated next to her boyfriend now.

"Lighten up, Farrah" the biology major joked. "He wasn't even that cute."

"He was adorable!" the youngest interjected.

"Everyone's entitled to their opinion," said Brooke. "Let's eat!"

The daughter in the middle seat stood up and said, "We have an announcement to make!" After a dramatic pause she screamed "we're getting married!" and flashed the new diamond ring on her finger. The youngest sister squealed with delight at the news. Her fiance joked to his future mother-in-law, "I think she said yes just so she can wear the monogrammed sweater you gave me for Christmas." The baseball player next to her asked her fiance, "Wow, what'd that rock set you back?"

"This calls for a toast!" roared Dad.

"Oh Honey, that's wonderful news!" Mom gushed. "I just happen to have some champagne right here. Lars, I know you don't drink alcohol, but would you mind pouring some champagne for Gabrielle next to you?" the mother asked, handing the bottle to Lars on her left. "Gabrielle, please pass the bottle around," she asked and then quickly added, "But no alcohol for my three babies, or anyone under 21 for that matter. Honey, there's a store downtown that's having a sale on wedding dresses. Will you have time to go look at some wedding dresses before you leave?"

"Sure Mom," her daughter answered. "We have a late flight out, so I can do that on the day we leave."

"Michael and I are celebrating New Years Eve at the Sheraton, Waikiki," one of the girls announced.

"What a coincidence," said the boy sitting next to her. "We're celebrating New Years at the Sheraton, Los Angeles. It's within walking distance of our apartment so we won't have to worry if we drink too much."

"That sounds like a better plan than we have. Somehow, just because my car holds a lot of people, I got roped into being the designated driver for the team" Danica said, looking pointedly at her boyfriend, who gestured to the boy from Princeton saying, "he gave me the idea!"

"Girls, your grandmother will be here on Sunday," the father announced. "She'd really like to see you all."

"Sorry Dad," the business major replied, "we have to leave tomorrow. There's a huge storm predicted to hit the Eastern United States this weekend and we need to get home before they close the airports. I noticed that each couple is leaving on a different day for six days after we leave."

"Sir, we're leaving before Sunday also, so we won't be able to make it either. I'm just glad we don't have to deal with that storm" said the wrestler.

The swimmer and water polo player announced their travel plans. One of them remarked that even though his girlfriend and he were departing for Oxford University two days earlier, both couples would get home on the same day.

The physics major said "I'll be here to see grandma, but unfortunately we're heading back to California before you go look at the wedding gowns."

"Well I'm glad you'll at least be here to see your grandma, but I wish you could stay longer" the dad said. "You know you're my favorite since you were my first to major in a physical science like me," he joked. "I have a tee time at the club on Monday, it's too bad you won't be here," the father remarked to the golfer. "Kyle's got a game next week but you don't," he said to the history major's boyfriend. "How about you join me on the links?"

"Sure!" the boyfriend replied enthusiastically.

"Since we're leaving the day after him, if you've got room for two more Dad, we just happened to bring our clubs" the second oldest said, winking at her boyfriend.

"It's a foursome then!" her dad said happily.

Ian grumbled, "Hank you lucky dog, I've wanted to play that course for years!"

The boyfriend of the political science major laughed, "I'd like to play there also, but Ian, at least I won't have to travel as far as you to get another opportunity."

---------

Identify the boyfriend and his sport, the school, and major for each daughter. Name the order that the daughters were born in and the day of the week that they leave to go home. What is the seating arrangement at the dinner table?

Bonus question: what year is it?

The engineer made his fence in a circle and said it was the most efficient.

The physicist made a long line and said that the length was infinite. Then he said that fencing half of the Earth was the best.

The mathematician laughed at the others and with his design, beat the others. What did he do?

A26. Stuck a stick in the ground and claimed that everything inside it was 'outside' and everything else was 'inside'?

Hi Mark,

Not quite...

Clue: The mathematician did make a fence !!

Interesting question, I note that the engineer and the physicist both had the same idea, only the former was working in 2 dimensions and the latter in 3. My first thought was the same as Mark's, but if that isn't the answer you're looking for then perhaps the mathematician merely put his fence around the base of, say, the Empire State building and claimed the entire floor space within.

Nope - but a lot better than certain answers!!

So the river isn't dry or frozen, the dog doesn't have a silly name and isn't wearing stilts, he doesn't use a boat or a bridge nor is he carried across... so I guess that leaves either magic, a trebuchet or a dog with a pilots licence.

Well the only further step I can think of for A26 would be if the mathematician fenced off all the bridges and tunnels leading into Manhattan Island and claimed all the area, including floor space, within.

A23 answer:

The mathematician made a small fence around himself and declared himself to be on the outside.

PS Don't blame me - I got this from a website !! And no, I won't tell you which one as they've got lots more of these...!!

Yes - the river was indeed frozen. Well done, sir!

Hi Mark,

So you mean to tell me that a "stick in the ground" counts as a fence ????

And I did give you a clue !!

It's just as well you're not a farmer, as you wouldn't have any sheep left

Hi Tim,

Alright, maybe not as a fence

But I got the principle of swapping the inside and outside around

I thought it was more coast than internal borders to begin with ... but Liechtenstein ruled that out!

I'm going to work on Q27, that's more my type of puzzle.

Hi Chris,

It's a far more intricate and "in depth" answer than that !!

Try again

Hi Mark,

Not even close - you really need to be thinking way outside the box on this one...and no, that's not a clue - and we're not talking shapes or fences or frozen rivers here...

I'll give a clue in a day or so...if it will help

But that's why it's a brain teaser - taxing your mind and getting all those neurons working overtime, thinking of all the permutations....

Their abbreviations are all elements?

Argentina - Ar = Argon
Australia - Au = Gold
Brazil - Br = Bromine
Chile - Ch = Chlorine
Colombia - Co = Copper
Liechtenstein - Li = Lithium
Madagascar - Ma = Magnesium
Slovenia - Sl = Silver

Stuck on what Czechoslovakia could be though?
