I got this in an email, and the original email had an excel sheet that you can put your name down on if you solved the riddle correctly. If you want the email just pm me and I'll send it to you, but for those who just want to solve it, i'm posting it now. Good luck!

QUOTE
This is a 5th grade maths problem. If you can't stand word maths
problems, just delete it now.

If you can open the spreadsheet, you'll see it's a very small list of
people who have gotten the correct number. This is not a trick
question.

This is a real maths problem so don't say that a bus has no legs.

There are 7 girls in a bus
Each girl has 7 backpacks
In each backpack, there are 7 big cats For every big cat there are 7
little cats
Question: How many legs are there in the bus?

The number of legs is the password to unlock the Excel sheet. If you
open it, add your name and send it on to see who else can unlock it.

16 legs are on the bus, cause the cats aren't on the bus they're in the back packs
and there has to be a bus driver, so that's my guess. 14 is my second guess.
72 is my third guess and if that's wrong too then 70 is my last guess.
And if they're all wrong then I need answers.

FOR ONE BIG CAT THERE'S 7 SMALL CATS.
CAT cat cat cat cat cat cat cat
CAT cat cat cat cat cat cat cat
CAT cat cat cat cat cat cat cat
CAT cat cat cat cat cat cat cat
CAT cat cat cat cat cat cat cat
CAT cat cat cat cat cat cat cat
CAT cat cat cat cat cat cat cat

THAT'S IN ONE BACKPACK. 56 CATS IN TOTAL.
THERE'S 7 BACKPACKS PER GIRL.
56 CATS X 7 BACKPACKS = 392 CATS PER GIRL.
TIMES THAT BY 7 GIRLS. 2744.
THAT'S THE NUMBER OF CATS.
CATS HAVE 4 LEGS. SO 2744 X 4 = 10976.
THERE IS 7 GIRLS X 2 LEGS = 14 LEGS.
PLUS THE DRIVER. WHO HAS TWO LEGS.
SO 10976 + 14 + 2.

10992. LEGS ON THE BUS.

NOW IF YOU DON'T COUNT THE GIRLS' LEGS OR THE DRIVER'S LEGS, THE ANSWER IS 10976. WITH THE GIRLS+DRIVER IS 10992. EITHER/OR, I HOPE I DID THE EQUATION RIGHT.

lolol

Girls => 7*2 = 14 legs

Backpacks => Big Cats = 4(7^3) = 1372 legs

Small Cats => 4(7^4) = 9604 legs

14 + 1372 + 9604 = 10990

I don't see why that's not right. :X

that is the right answer. 10990 is the right answer. 10992 is not the right answer.

I got 238..

7 girls = 14 legs
7 big cats = 28 legs
every big cat has 7 little cats so thats 7*7 = 49 little cats
49 little cats times 4 = 196 legs

14 legs + 28 legs + 196 legs = 238 legs ?

LOL i think thats right but if its not.. BLEH. LOL T___T! took me like 10 mintes.

I'm assuming the bus is NOT being driven and is sitting still.

Then subtract 2 from my answer and I'm still right. Yay smile.gif

LOL! i sent the riddle to my sister and this was her response:

"this questions is so stupid. all the cats would be dead because they're all squished into one backpack with 14 other cats in a bus that apparently doesnt move because there is no bus driver."

And in that moment, I swear we were infinite.
