Answer to short puzzle

December 19, 2007

Puzzle2 days ago we posed a small puzzle as set out below

There is a bus with 7 girls

Each girl carries 7 bags

Inside each bag there are 7 cats

Every cat has 7 kittens

All cats and kittens have 4 legs

Question: How many legs are in the bus?

The answer is 10,990 That is if you don’t count that there might be a bus driver.

So how did we work it out

Well 7 girls with 7 handbags is 7×7 handbags = 49 handbags

There are 7 cats in each handbag so 7×49 = 343 Cats

Each cat has 7 kittens so there are 7×343 = 2401 Kittens

So now adding up the legs there are;

7 Girls with 2 legs each so 7×2 = 14 Legs for the girls

There are 343 cats so 343×4 = 1372 legs for the cats

There are 2401 kittens so 2401×4 = 9604 legs for the kittens

So there are a total of 14+1372+9604 = 10,990 legs altogether.

For those of you who got this right you are definitely in the minority as very few were able to get it.
