Now This Is Just Freaky....

[K'riq Sa]

Now this is just downright freaky. A friend sent me this the other day, and I just can not for the life of me figure out how this is done.

That is freaky.

On the numbers side of it, there's only nine numbers that would ever be chosen, but how they get the right gift for whichever of those numbers you've picked, I don't know.

 

[Gary Mitchell]

That is freaky.

It's the same item on each of the 9 numbers that would be chosen for that session. Whenever you take the test again it changes the items on those numbers to try and disguise that they are the same. The nine numbers are 9, 18, 27, 36, ,45, 54,63,72, and 81. The items on those numbers will always be the same.

 

[trampledamage]

oh, didn't think to look across all of them each time. Nice bit of figuring, sojourner.

this = fail

I chose 87 for the two digit number. According to the formula: 87 - 8 - 7 = 65 the program's woman should have guessed an "educational book", she guesses "box of tea"
take two, should be "bread maker", she guesses "oven mitt"
take three, "scented candle", she guesses "board game"

It didn't guess mine either.

Um, no, 87 - 7 - 8 = 72.

The key is that you're always subtracting off the ones digit, so effectively if X is the tens digit, then the number you end up with is 9*X. That's why all the possible answers are multiples of 9.

If the program didn't guess your number, you did the math wrong. It's as simple as that.

Yeah I did the math wrong the first time...it guessed it just now.

 

[Zulu Romeo]

Ah. the power of the number 9 to influence the choices we make...

 

[RJDiogenes]

Number 9... number 9... number 9....

 

[K'riq Sa]

well i guess i can take off my tin foil hat, and let the kids out of the 50 gal barrels in the basement...

I learned a new math trick today!

 

[John Picard]

She didn't guess mine.

 

[sojourner]

^then you did the math wrong.

Redid it and she guessed.
