This is not a trick question. This is a real math 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?
Private message or shout me when you think you know....if you post it...duh....no one else will try it!
