There's a bus with 7 girls

Each girl carries 7 bags

Each bag carries 7 big cats

Each big cat carries 7 smaller cats

(All the cats have 4 legs)

Question: how many legs are on the bus?

Thanks

the original problem never states that there is a bus driver. Perhaps one of the seven girls IS the bus driver. Or perhaps there is a security guard, a ASPCA representative, or 100 cockroaches on the bus as well. If you want to start making assumptions, go ahead, but i'd stick with what the original problem states as facts, and stop there.

Well, the original problem also doesn't mention that the girls have two legs apiece. That seems obvious, but the problem

Each girl already has 392 cats to deal with, and now one is expected to drive as well?

*did*state that each cat has four legs, which seems equally obvious. The omission seems odd. For all we know, some of the girls could be amputees.**[Fred]: Perhaps one of the seven girls IS the bus driver.**Each girl already has 392 cats to deal with, and now one is expected to drive as well?
