My brother-in-law sent me this via e-mail. See if you can figure it out.
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?
