Question from leria, a student:

This is not a trick question. This is a real math problems,.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.

How many legs are there in the bus? One hint? it's a 6 digit number

14 girl legs
49 times 4 big cat legs
49 times 49 times 4 little cat legs

I'm unable to get a 5 digit number. Please help


Look at your calculations again. There are 7 girls and each has 7 backpacks. Thus there are 7 × 7 = 49 backpacks. In each backpack is 7 cats so there are 49 × 7 = 343 big cats. Thus there are 343 × 4 big cat legs.

You say that this is not a trick question but it comes from a traditional nursery rhyme (puzzle) that might be considered a trick question.
