Here’s a little brain-teaser for you. There are these seven kids who love, love, love cats. They are packing their cats into carriers and going to Camp Catawaller for a week. While there, they will camp out in tents and trees (the cats will be in the trees), go fishing (with the proceeds going mostly to the cats), go hiking, and will of course roast marshmallows and fish sticks over an open fire. No cell phones and no laser lights allowed!
None of that has anything to do with the brain teaser, I just wanted to give you a little background before I lay out the brain teaser. So, put your thinking caps on, here it comes…
There is a bus with 7 children inside. They all love cats.
Each child has 7 cat carriers. (A lot to handle, but these are talented kids!)
Inside each carrier there are 7 big cats. (These are very roomy carriers.)
Each big cat has 7 small cats. (They’re kittens, actually.)
All of the cats and kittens have 4 legs each. (Standard amount of legs.)
So, how many legs are on the bus?
Here’s a recap:
- There are 7 children on the bus.
- Each child has 7 carriers.
- Inside each carrier there are 7 big cats.
- Each big cat has 7 small cats.
- All cats have 4 legs each.
- How many legs are on the bus?
Ok, there really 3 possible answers that I will accept as correct. One would be considered a trick question, and another would kinda sorta be, too. And then there is just doing the math. Let’s see if all 3 answers are given!
555 legs I think
If you include the driver I count 555 legs
More than I care to count at the moment.

WAY more than that, Vicki!
well really there Are no legs on the bus except tyres…..but would it including driver be 1584 legs inside the bus with all the cats and kittens
Threre’s one of the answers! The trick question – there are NO legs on the bus, only on the children and the cats. And counting the driver’s legs with the kinda sorta trick answer. But as for the math, 1584 is still WAY low!

Hi Georgia what does DF mean…I doing the math again im on pain relief so a bit thick at the moment ha ha
I just helped my son solve a very similar problem for a school assignment. However, instead of kids on the bus, there were farmers with bushels. Here was our answer.
First of all, I had 7 farmers who each had 7 baskets. I multiplied 7 farmers by 7 baskets. The answer was 49 baskets.
Then, each basket had 7 cats. So, 49 baskets times 7 cats equals 343 cats. If each cat had seven kittens then I would need to multiply 343 X 7. that makes 2,401 kittens.
Since the question asks for how many legs are there in all, I multiplied 7 X 2 to find out that there were 14 human legs.
Then, I added 343 cats to 2,401 Kittens. 343 + 2,401 = 2,744 felines altogether. If each feline has four legs, then I would need to multiply 2,744 felines by four legs. 2,744 X 4 = 10,976 feline legs.
If I add the human legs to the feline legs that means I need to add 14 + 10,976 = 10,990 legs all together.
