Question

There are 7 girls on 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 on the bus, not counting the driver?​

Answer 1

Answer:

there were 42 legs not counting the driver

Answer 2

Answer:

Let's start with the girl legs. There are 7 girls × 2 = 14 girl legs. Now let's count the cat legs. There are 49 backpacks which means there are 343 cats × 4 = 1,372 cat legs. Finally, let's count the kitten legs. There are 343 cats which means there are 2,401 kittens × 4 = 9,604 kitten legs. The total number of legs is 14 + 1,372 + 9,604 = 10,990 (or 10,992 if you're assuming there's a bus driver).
