There is a bus with 7 girls........

There is a bus with 7 girls.

Each girl has 7 bags.

In each bag, there are 7 big cats.

Each big cat has 7 little cats.

Each cat has 4 legs.

How many legs are present in the bus?

preemptive @Evan:
Actaully none of the legs were 'present' because it's not Christmas!

7 girls - 14 legs
49 bags - 0 legs
343 big cats - 1372 legs
2401 little cats- 9604 legs

Total = 10990 legs

AND, this may be the trick of the puzzle, if you include a bus driver... 10992 legs.

Excellent answer!

Altho', playing Evan's Advocate here...

"The question only says how many girls there are on the bus. It doesn't say how many boys there are. So the answer is... unknown!"

Then I would counter that by pointing out that it doesn't specify that each girl has the full complement of legs either.

Yeah, choke on that, Evan! :-)

One bag has 56 cats with a total of 224 legs so 7 bags have 7*224= 1568 legs.
7 girls have 14 legs so total total legs are 1582!

khushi ji there are total 49 bags.each girl have 7 bags.
so 49*224=10976
& 14 legs of 7 girls.total legs are 10990!

only 7 girls are on the bus =
14 legs.
bags and cats are not on the bus.
If there is a driver, then add two legs. No other passengers are mentioned, thus there should be no other people onboard.
Otherwise (as stated earlier) it is impossible to know.
But given the original statements there should only be 14 legs.

"There is a bus with 7 girls." "Each girl has 7 bags." Where does the problem state that any girl or any bag is "in" the bus? The primary failure revealed! :)
