Count legs and legs

Count legs and legs

In a bus driven by a single driver there are 7 children with 7 backpacks each. Each backpack has 7 cats and each cat has its 7 kittens.

How many legs and legs are on the bus?

Solution

There is no trick in the solution. This is a simple math problem but that will make more than one fall:

"7 children x 7 backpacks x 7 cats x 4 legs of each cat = 1372 legs of cats

"7 children x 7 backpacks x 7 cats x 7 kittens x 4 legs = 9604 kitten legs

"7 children x 2 legs = 14 children legs

"1 driver x 2 legs = 2 driver's legs

Total: 1372 + 9604 = 10976 legs and 14 + 2 = 16 legs
