If there are 7 girls in a bus, and each girl has seven bags and there are 7 big cats in each bag, and each big cat has 7 small cats with it, then, how many legs are there in the bus?

7 times 7 times 7 + 2 (for the driver) = 345 LEGS

(7 time 2) * 7 bags * (7 times 4) big cats * (7 time 4) small cats + 2 driver = 76, 834

7 girls x 2 = 14
7 girls x 7 bags x 7 big cats x 4 = 1372
7^3 x 7 small cats x 4 = 9604
driver x 2 = 2

= 10,992

That's assuming the bus contains no amputees, boys, or centipedes.

i was wondering where did this one go wrong,
wont that mean each girl has two legs and each leg has 7 bags, each cat has 4 legs and each leg has 7 kittens.
this is a legendary question.

help! I only have one head...yet having lots of headache...
(12*3 +20*3*12)8 + 2*2 +3*4 +2*1....
does a monkey have 4 legs or two hands...and two legs?
does a spider have 8 legs or six legs..i dont remember....(or is it a spiderman?)

4*4=16 corners
16*2=32 webs
32 - 12 = 20 webs w/ big spiders
20*3 = 60 big spiders
(60*12) + (12*3)= 756 small spiders
30+756 = 786 spiders total

756*8 + 2*2 + 3*4 + monkey = 6066 legs in the building

That would make 6132 toes, unless one ore more of the cats are [SIZE=-1]polydactl.[/SIZE]

(Any math errors are to be blamed on my keyboard, not on me. Honest.)

A normal spider have 8 legs.

Everyones answer is wrong .Try agin.

Thingmaker the question is to calculate legs.

And according to thingmaker a cat have 18 toes........maybe there are 10 toes in the forward claws and 8 in backward claws.

Brainteaser has been in the proximity of a cat! They do indeed have only four toes on each back foot. Same as dogs. Note that I am indeed counting the dew-claw as a toe.
I still maintain my keyboard is to blame for any errors!

pretty well....from personal experience
the cat looked something like this that time.

is this a trick question?
are some small spiders common or something...or any calculation error..
maybe the for corners of my mind got webs over them.
