Mr Pebs has just brought this home and I got it totally wrong on the first go, so thought I would see if you cleverclogs out there would like a go...

There are seven girls on a bus and each girl has seven backpacks. In each backpack there are seven big cats. For every seven big cats, there are seven little cats.

How many legs are there on the bus?

(this isnt a trick question of buses have wheels - you actually need to work out the number of legs :) )

"There are seven girls on a bus and each girl has seven backpacks. In each backpack there are seven big cats. For every seven big cats, there are seven little cats."

7 x 2 + 7 x 7 x 4 + 7 x 7 : 7 x 7 x 4 = 420

Sorry, I'm pish at maths but that's my try. At least the thread won't be boring and without mistakes!

thanks for making the thread interesting HP :rolleyes:

and nope, thats not the answer.

Is it 2758?

nope...

my maths sucks but here's my guess:

"There are seven girls on a bus and each girl has seven backpacks. In each backpack there are seven big cats. For every seven big cats, there are seven little cats."

(7x2)+ (49 x 7 x 4) + (7 x 7 x 4) = 14 + 1372 + 196 = 1582

that's a lot of legs

(although i'm sure it's wrong.....)

not there yet...

Is this something to do with the fact cats don't have feet, they have paws? Making the answer 14? And if there is a driver as well as the girls...then 16?

can i ask - when you say "for every 7 big cats there are 7 small cats" do you mean for EVERY big cat there is 7 small cats or for every 7 big cats there are 7 small cats??? :unsure:

I read it as for every big cat there are 7 small cats....which is a lot!

ok, that's where my sums went wrong...... :blink:

There are seven girls on a bus and each girl has seven backpacks. In each backpack there are seven big cats. For every seven big cats, there are seven little cats.


Ok - 7 girls = 14 legs

49 backpacks - each backpack contains 14 cats

686 cats = 2744

Still the same result! :yikes:

Oh, I think I read it wrong too...quelle surprise! :doh:

I go 2760, cos the driver has two legs :D

Unless a cat is driving then it's 2762 legs :lol:

ok this is how I see it then (if cats do indeed have feet)

there are 7 * 7 * 7 big cats = 343

and 7 * 7 * 7 * 7 small cats = 2401

and seven girls

so feet = (7*2) + (343 * 4) + (2401 * 4) = 10990 feet (and two more if there is a separate driver)

(7x2)+ (49 x 7 x 4) + (343 x 7 x 4) = 14 + 1372 + 9604 = 10990

same result as me....




















but I beat you to it :P :P

so it may be wrong....

:giggle:

it's entirely possible - my maths is appalling..... :P

but i do need to ask - firstly, how big are these girls, are they weightlifters or something? secondly, how big are the back packs? putting that many cats in a back pack has got to be animal cruelty! thirdly, how big is this bus???

Thats what I get... :unsure:

I don't think it's that because each of the 7 big cats have 7 small cats....well that's how I read it.

Although to be honest as Jo mentioned that's gotta bne one big bus. Imagine the smell :o

The answer is none in another logic puzzle cos a bus doesn't have legs.

sorry - it wasnt clear was it? for every big cat, there is seven small cats...

but you got there in the end... 10990 is the correct answer :clap:

and I also threw down my pencil in disgust and said you wouldnt get them all on the bus anyway :unsure:

when doing my calculations - I kept forgetting there was seven backpacks..

thats why I said it wasnt that type of answer at the beginning ;)

I tried that at first and Mr Pebs told me off and to start making notes on amounts of cats...

Mr Pebs is such a tease :lol:

tell me about it :chesire:

am not!!!! :P

:lmaao: :kiss2:

Mr Pebs is a woman? :unsure:

:giggle:

it's a running joke from aaaages ago when i said i was actually Mr Pebs...... :unsure:

um....it was funny at the time :P

I still :giggle: I guess you had to be there :unsure:
