14 + 1568 = 1582 legs total.

My math may be rushed, as I am in lecture right now.

I am probably missing something because this seems like it shouldnt be hard at all.

I got this too.

Edit** I did it completely differently

7 girls = 14 legs
49 big cats = 196 legs
343 little cats = 1372 legs

Total legs = 1582

That answer is only for 1 girl - you forgot that there are 7 girls.

I hate those jokes so to lighten the mood
The brain teaser made me think of this brain teaser.

Locke the homeless Hobo had a cigarette addiction. Locke had no money so in order to feed this addiction he had to collect cigarette butts and every seven he collected he could make a new cigarette.
After collecting 49 Cigarette butts, how many Cigarettes can Locke make?

8

Edit: figured I'd add a little bit of an explination.
He's got 49 cigarette butts, so he can make 7 smokes out of that.
When those 7 smokes are done, he'll have 7 buts left from those smokes, so he can use those to make one more, for a total of 8.

You forgot that each girl has 7 backpacks, that all contain cats.
There are 343 big cats and 2401 little cats

7*2=14
343*4=1372
2401*4=9604

9604 + 1372 + 14 = 10990
Just like a lot of folks have already said.

There are 49 backpacks. (7 girls with 7 backpacks each... 7*7=49)
Therefore there are 49 big cats and 343 small cats

7 girls = 14 legs
49 big cats = 196 legs
343 small cats = 1372 legs

14+196+1372=1582


edit... I'm wrong. There are 343 big and 2401 small... oopsie...

Real answer is: 10990

[Eagle Eye]

but there are 7 big cats for every backpack
7*7*7=343

I just realized I missed the fact they had 7 backpacks each., so it is clearly wrong

When I was first asked that riddle I was in grade 9 and it was by our math teacher. Me thinks the real riddle involves roaches

I remembered the backpacks but forgot that there are seven big cats in each instead of one.

What is truly alarming here is that Southland transportation has a seven year old driving the bus, because clearly there is no bus driver. I am certain there are some labour laws being broken here...

Yeah, that's the answer. Took me another 15 mintues before i got it.

They each have 7 backpacks with 7 adult cats and 7 kittens per adult cat in each backpack =8 cats (1 adult cat + 7 kittens)X4 legs=32 Legs x 7 backpacks=224 legs (per backpack) X 7 bags per Girl=1568 legs per girl x 7girls =10,976 + (7girlsX2 legs=14 legs) = 10.990

I forgot to add the girls legs

Some arer good at math and reasonong skills and others are not.

A good friend of mine just sent an email asking for the answer. I replied keep working on it. I won't type his further reply here

[foofighter15]

so it wasn't a trick? it was just a weird math question?
Disappointed Level at Capacity!

Haha my good friend just asked what the trick was

[Phanuthier]

I have a fun one.

3 guy walk into a hotel and request a room. (Don't ask why 3 guys are getting a room) The bell boy at the service desk says its $30, so each guy pays $10. As the bell boy at the service desk is putting away the 3 $10 bills, the hotel manager returns, see's this and says "The room is not $30, its $25, on sale this week. Go return $5."

As the bell boy is going up the elevator, he's wondering how he is going to split $5 between 3 boys - so he reasons "since I'm such a good guy, I'll give each guy $1 (3 x $1 = $3) and I'll keep $2 myself.

Now, each guy renting the room has paid $9, and the bell boy keeps $2:
$2 + (3 x $9) = $29

Where did the missing $1 go?

[foofighter15]

ok my math is most likley off, but if he has to give back 5 dollars. then wouldn't he be giving back dollar 30, 29, 28, 27, 26, thus putting the original 25 back in the cash register?

[Resolute 14]

Its still in the cash register.

Each guy paid $9, for a total of $27, while the bellboy stole $2. $25 left for the hotel.

$2 + (3 x $9) = $29

Where did the missing $1 go?

It didn't go anywhere, the $27 that they paid, + what the bellboy keeps shoudn't add up $30.

Men paid $9 each, wich is $27.
$25 to the room and $2 to the bell boy.

So 25 + 2 = 27

The "Missing dollar" doesn't come from faulty math, rather from faulty logic.

[MarchHare]

Before:
$0 in cash register
$0 in bellboy's pocket
$10 in each man's pocket (x3)

$30 total

After:
$25 in cash register
$2 in bellboy's pocket
$1 in each man's pocket (x3)

$30 total
