This will drive you nuts...?

Have fun.....

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

Question: How many legs are there in the bus?

10990. 10992 if you include the driver.
How is it solved?

Each cat has 4 legs; each kid has 2 legs.

The Rule of 7

Start with 1 pack, then add-on
there are 7 big cats & 7 little cats in it.
7 little cats x 4 legs/cat= 28 legs + 1 big cat= 32 legs
32 legs x 7 big cats= 224 legs
224 legs x 7 packs= 1568 legs
1568 legs x 7 kids= 10976 legs
7 kids x 2 legs/kid= 14 kid legs
10976 cat legs + 14 kid legs= 10990 legs on the bus.

Something to make you use your brain.
Although, I must admit I hate math/numbers with a passion. Report It

14...you only said that the 7 girls are on the bus

What drives me nuts is seeing this question almost every day.

56.... you never said the little cats were on the bus

16 legs, the 7 girls and the bus driver.

36 legs

seven pairs of legs are there in bus

There is a huge number of legs. Each cat has 4, and each girl has two. And though there aren't many girls, there are an awful lot of cats!

how many seats are on the bus and how many legs does each seat have?

10990 legs 5495 pair of legs

14 human legs (7 pairs) of 7 girls

10976 cat legs (5488 pairs) of 2744 cats

1372 big cat's legs (686 pairs) of 343 big cats

9604 small cat's legs (4802 pairs) of 2401 small cats

10990
7 girls=14 legs
7 girls x 7 backbacks= 49 backpacks
49 x 7 big cats=343 big cats x 4= 1372 cat legs
343 big cats x 7 little cats= 2401 little cats x 4=9604 little kitty legs
9604+1372=10976+14 girl legs=10990

that just makes me nausous looking at all the math i would have to do to figure that out.

7 x 7= 49 backpacks
49 x 7= 343 big cats
343 x 7= 2401 little cats

7 girls= 14 legs
343 big cats= 1372 legs
2401 little cats= 9604 legs

plus or minus 2 for the bus driver equals the total of

10990 +/- 2 for driver
