There is one bus with 7 girls in it. Each girl has 7 backpacks and each backpack has 7 big cats. Each big cat had 7 little cats. How many legs are there all together?
You're plainly asking the wrong question. The right question is: How much weight are these poor children expected to carry, and will the bus be able to carry 7 of them?
Each backpack has 7*7 kittens, for a total of 24.5Kg. It also has 7 cats, for another 28Kg, totalling 52.5kg. I hope the backpacks are of sturdy construction.
Each unfortunate child is carrying 7 of these backpacks, for a total of 367.5kg of screaming, scratching cat. To give you an idea, the world record for weightlifting in the men's 56kg class is a mere 305kg. The child also weighs another 40kg, bringing the total up to 407.5kg per person.
7 on the bus makes 2852.5kg. Load limits for buses are harder to come by, but assuming this is a school bus (given the 7 children, this seems plausible), your average school bus is equipped to deal with perhaps 25 children, so probably no more than about 1500kg.
Clearly, these 7 girls could not carry this many cats, and even if they could, the bus wouldn't be going anywhere.
In summary, I find your claim preposterous.
Funguy: Here's how I calculated it
7x4=28 (number of big cats in each backpack x how many legs they each have = 28 big cats legs)
28x7=196 (Number of legs of 7 cats x number of big cats in the bag= number of all little cats legs)
196+28=224 (Big cats legs + little cats legs = all legs in each back pack)
224x7=1568 (all legs in each backpack x how many one girl has = number of legs each girl carries)
1568+2=1570 (Number of all legs in backpacks + girl's legs = number of legs per unit)
1570x7=10, 990 (number of legs in one unit x number of units = total number of legs)
A unit refers to how many legs all up of a girl with 7 backpacks, each containing 7 cats, each cat with 7 kittens.
Then, you could maybe add on 2 more legs in the equation, if there is the addition of a bus driver. You could also add more or less, assuming there may be other passengers on the bus, or some of them may be amputees.
Arachnid, I cannot find anywhere in the original question that each of of the girls are expected to carry the backpacks - rather, it simply states they have them on the bus with them, how they got there is not stated (cats and bags assembled on the bus?). The assumption that the bus is a school bus is also a bold one, as is the fact that a school bus carries 25 - the average seating for a suburban bus is 39 seats (and I would assume that School Buses are the same, or at the least 33), and a touring (long distance bus) is designed to carry on average 43 passengers. A touring bus is also designed so that it can carry up to 20kg of luggage per passenger so I am lead to believe.
If they were using a Touring Bus, the claim is quite reasonable by my calculations. Not that the question claimed it was possible, but rather asked how many legs there were.
This question was asked about 10 hours ago by spaschal35 and 10990 was the answer I posted. Each 'pack has 7cat and 7 x 7 kit(ten)s for a total of 56 felines per 'pack. Each girl has 7 'packs = 7 x 56 felines = 392 of those suckers 7 girls x 392 cats per girl = 2744 tabbies 2744 cats have 10976 legs among them. Add to that the 7 pairs of legs on the girls (hint = 14) and you have 10990 legs ... 10992 if you count the bus driver.
Or...2401?
Wait...does each girl have one backpack each? Or does each girl have 7 backpacks each? If so..that would make 16807? Oh no im so confused :( I'm too mathematical..or not. lol
Arachnid, sometimes I think you're the most cantankerous gentleman I have ever met! (That, and I think those schoolgirls are a bit too skinny!)
This was just asked:

Maybe that original poster knows the answer?
I got 10,990, but I don't know the answer. That is why I posted it :)
Hahaha I'm laughingg so much at arachnid's answer. Heheheee. LOL
do you know the answer but heres my guess:2,758...am I right?
This reminds me of "As I was going to St Ives..."
Im confuzzled!!!
One None Some I dont know
well, how many people are in the bus total?
my math teacher gave us that problem!:)
I got 10,990. whats the answer??
None...=]
2758
