This math problem had my family and me engrossed at a recent dinner. It's not a trick question. Just follow standard math rules to find the answer.

 

Here goes:

 

"Seven girls are on a bus. Each girl has seven backpacks with seven big cats. Each big cat has seven little cats. How many legs are there inside the bus?"

 

Sounds easy enough, but I have a feeling this might give a few people some fits.

 

What's the answer?

1582?

Does the bus driver count?

 

If so, can I change my answer to 1,584?

There are 16 legs on the bus

Zero.

 

A bus has wheels, not legs.

I made that mistake too. I actually counted the bus driver originally, and that was my mistake. Here's a hint: You are WAY off. Hope that helps. :D

I guess technically, you are correct. Didn't think of it that way. However, let me rephrase the original question. How many legs are there inside the bus?

Zero.

That's not fair...if the question stats that "there are seven girls on the bus", then it stands to reason that their legs are on the bus.

7 girls = 14 legs

49 big cats = 196 legs

 

Let's assume the big cats have 7 kittens each, but have not given birth yet.

 

So that would be 210 visible legs. 212 if you count the driver (and assume 2 legs).

 

Is that fair, 5Wide?
