| Whoa, great teaser!!!
At first I was thinking what kind of calculations I'd have to do to get the answer... then suddenly realized the answer when I thought about starting backwards at the last bridge!
I think this is what makes this teaser so great - the answer isn't what you would expect when you first start reading it!  |

jimrcook
Mar 23, 2005
| My sister gave this interesting alternative. Assume the trolls in the past were NOT nice trolls, so they now have a bunch of cakes. In that case, if you start with one cake, you give the troll a half a cake, and the troll (now nice) takes a whole one from the stock pile previously amassed and gives it to you. You now have 1.5 cakes. I find it very interesting that after seven bridges, you will have (mathematically) within 1% of two cakes to give to gramma. Since cakes surely vary by more than that anyway, this would surely satisfy gramma on her birthday, and would be a great birthday story to boot. |

Laboomsikashod
Sep 19, 2005
| I was thinking along the same lines as jimrcook's solution. Except you could start with no cakes at all, so at the 1st bridge you give 0 and take 1 cake. continue to 7th bridge and you can go back and forth across the 7th bridge until you cake total reaches infinitely close to 2 cakes such that grandma can't tell the difference. |
Laboomsikashod
Sep 19, 2005
| Just realised the my above solution is wrong in that:
1. the cakes will not be made you, and you want to give grandma cakes you've made.
2. question requires EXACTLY 2 cakes, above solution only gives 1.999999..... cakes.

| This is actually a very good one.
Mathematically speaking you can also start with 4/7 (0.5714) cakes and get to 2 cakes by 7-th bridge. This is more economical but the pressure is on the first troll to give you 1 cake even though you gave him less than one  |
lmurray   
Mar 19, 2006
| I DON'T KNOW WHO'S SPEAKING FOR MATHMAMETICS, BUT THE ONLY WAY TO GET TO GRANDMA'S WITH "EXACTLY" TWO CAKES, IS TO START WITH TWO CAKES, NOT 4/7!!!
ANY NUMBER LESS THAN 2 WILL NOT GET YOU TWO CAKES, CLOSE, BUT NO CIGAR. |
brainster   
Mar 19, 2006
| Well I went all mathematical and wrote down a formula -
x-7(0.5x)+7 = 2
where x is what you started with. By now I should have known the answer, but still my superactive brain (as it gets sometimes) actually solved this bit by bit and arrived at the shocking answer:2!
Still laughing!  |

shawneeo   
Mar 19, 2006
| I started out also trying to write a formula, but realized that you can't just multiply by 7 because the amount changes each time before it's halved, so instead of doing the operations on x seven times you have to do the operation on x once, then do the operation on that amount, and so on.
I LOVE this one!!! This is classic, it's what I think of when I think of a teaser, because it gets you thinking and calculating, and then because of one of those magical properties of numbers the answer is simple!
I also got it, YAY!, by stopping the scribbling and starting at the end, with two, and realized, Voila! Eureka! That eureka feeling is what I really LOVE about A GOOD TEASER! Thanks so much! I sent it to some friends and family!  |

But seriously. really fun teaser you got me writing all this numbers cus I wanted to leave the trolls with at least on cake. But the answer came to after I finished reading the teaser. GOOD WORK MAN!! |

ginny322   
Mar 19, 2006
| I thought this was hard... and then I realized the reason why I kept getting the wrong answer was because I had forgotten the part about getting one cake back from each troll!

| Great teaser! Ugh it didn't occur to me that working backwards would work so I started with numbers like 200 and 180 and stuff. After that didn't work, I worked backwards and I got it. I really liked the teaser! It's going on my favorites list!!  |
iteachkids   
Mar 19, 2006
| Maybe including a calculator was what threw many us off. Like brainster and shawneeo, I decided do it without your calculator, so I got out paper (like a good algebra student) and tried to create an equation ... the whole bit. Argghhh! You got a BUNCH of us! Thanks for the FUN! It is a FAVE, for sure.  |

mysweetjolie 
Mar 20, 2006
| I loved this teaser. I sat down to do it and I thought, this is really hard. How do I do this? So I started from the bottom, with two cakes, and soon realized the answer was 2. But I thought, it surely couldn't be that easy so I used a bunch of numbers and divided by 2 and added one, but I kept getting fractions. So then I realized that it must be 2 and how thrilled I was to find that I was right! Thanks for a really great teaser.  |

Aug 30, 2006
| Good puzzle.
I started thinking in binary: the last digit must be zero before visiting each troll, and each troll increments the number by one. Using this I got 10000010 in binary, which is 130 in decimal.
Hence, there are 2 solutions.  |
ulan
Aug 30, 2006
| I've just found out that 130 is wrong
There will remain 4 cakes, not 2. |

Nov 11, 2006
| x(n+1) = x(n)/2 + 1;
=> x(n) = 2( x(n+1) - 1 )
x7 = 2; => x6 = 2(2-1) = 2;
x6 = 2; => x5 = 2(2-1) = 2;
x5 = 2; => x4 = 2(2-1) = 2;
..
..
x2 = 2; => x1 = 2(2-1) = 2;
Nice question; |

auntiesis   
Mar 19, 2007
| I started with the thought that you had to end up at Grama's house with 2 cakes . Therefore the 7th troll had to give you 1 cake to add to your 1 cake and the rest was easy. So easy that I got out the paper, pencil, and calculator before I realized it wasn't hard at all. But I can see how it could confuse some people into thinking it was a big math problem. It should be called a trick. But whatever it is , I loved it.  |

| A good puzzle. You can either get bogged down quickly with complicated maths and get the wrong answer or think laterally and get the correct answer quite quickly. Luckily my lateral thinking muscle woke up for just long enough otherwise I'd still be on it now!
Well done. Nice storyline and good fun. |
frozenrose_885   
Mar 19, 2007
| That really tricked me. I didn't try to figure it out though, since I knew that with every other even number, if you divide it in two then add one you will get an odd, which would divide into somthing and 1/2. Didnt think of the only exception... |

| Oneheartbroken: think of it this way....you leave with 2 cakes. At the first bridge, give one to the first troll. Now you have 1 and he has 1. He's going to be nice and give you one back. Now you have 2 again. On to the next bridge and it all repeats until you get to Grandma's! |

| I did 2 to the 7th power, then added 7..... gave me 263 cakes!!!!!
But if I was a troll, then I would want a cake, and I would realize that taking 1/2 from 2 and giving one back would leave me with nothing, and I would be angry. |
jcann   
Mar 19, 2007
| But if the troll takes one cake and then gives one back, why does he bother? |
asfidelino

| That was easy, but fun. You would think that the trolls would want to keep some of cupcakes for themselves, but they are not very smart in this story.  |
jacstop 
Mar 20, 2007
| 2 is the obvious answer which of course I answered but when you work out the problem for any number from 0-100 you get pretty darn close to 2 anyway so the smart thing to do would be to take 3 so you can always have a portion to taste for yourself. |

Spockinasmock 
Dec 30, 2007
| Nice question, but I've seen a couple of people giving incorrect or complex formulas. Here's the algebra that gives the solution:
( ( ( ( ( ( ( ( ( ( ( (x/2+1) /2)+1) /2) +1) /2) +1) /2) +1) /2) +1) /2) +1 = 2.
After doing the first 2 operations, the simple solution shows itself without having to complete the whole sequence, but it's nice if you want to solve for a different amount of cakes . |
uhhhh   
Jan 13, 2008
| That is wrong... if you bring two cakes, you give half of one each time. That means you have 1.5 afterwards, then 2.5?! |

| lol why some peope think it's 130? its two: >2< !!! because everytime you're giving 2/2=1, and they give you this 1 back! so, number of the cakes doesn't change! |

| I loved this one. When working with math, you have to start with the known. We know we want 2 at the end, and at each bridge we leave with (x/2) + 1 cake.
So after the last bridge we want (x/2) + 1 = 2
x/2 = 1
x = 2
So the only way to have 2 cakes for grandma is to have 2 cakes before the last bridge! Since we need 2 cakes before the last bridge, we see that it doesn't matter how many bridges there are, if we have 2 going in, we have 2 going out, thus the answer is 2.
Great puzzle! |

| Another way was to put the cakes in your wagon and carry a gun. Shoot the troll before you cross the bridge.  |

| We got this teaser for a school problem. We solved it in like two seconds, but it's still a fun teaser.

| I missed the part where it said you got a cake back so I did the math and came up with a large number. I knew this could not be right so reread the question (correctly this time) *FACEPALM* Duh! Don't even need math to figure it out!
lol @Doehead - that would work too.. But hope you are only using a tranq gun. No need to kill the kindly trolls.
I miss reading his comments too Gayle |

| Actually very simple math. I heard that DOEHEAD bought a new convertible and drove off into the sunset. I miss him too. |

| I loved it! One of the few math ones I got. I started working backwards and I'm like, okay, so after the 6th I have two...wait, wouldn't that work for every one? Great teaser. Could also go in the trick category, although it's not really a trick. Just misleading.  |
