Anybody like math brain bogglers?
 
This was found in a 5th grade math book, but they used cats! Try your math skills. Let me know if you want me to PM you the answer to see if you are right.


There are 7 girls on a bus.

Each girl is carrying 7 backpacks.

In each backpack there are 7 cottony Yorkies.

For every cottony Yorkie there are 7 silky Yorkies.


How many legs are there on the bus?

Tnyorkiemom 07-10-2008 08:01 AM
ok...238 without counting the bus driver...if you count the driver there are 240 legs on the bus

pookiebear 07-10-2008 08:03 AM
Nope. we're only talking about little girls, and yorkies.

Gingergirlsmom 07-10-2008 08:04 AM
My turn,

no legs...busses have wheels :)

Tnyorkiemom 07-10-2008 08:05 AM
ok....i hate this number so im separating it....1.....6....6...6.......there you go....i forgot about their being 7 backpacks

LuvnmyYorkie 07-10-2008 08:08 AM
10990

Yorkieforme 07-10-2008 08:10 AM
OK..I say 406 legs....

pookiebear 07-10-2008 08:11 AM
no one is even close.....

Charlene1963 07-10-2008 08:14 AM
None...the bus has wheels.

LuvnmyYorkie 07-10-2008 08:14 AM
Ok, can you PM me the answer??

Tnyorkiemom 07-10-2008 08:15 AM
...1387

hmcdowell1 07-10-2008 08:15 AM
(lol, you're right, busses don't have legs) But if we didn't take that literally, wouldn't it be:

7 girls x 2 legs = 14
49 cotton yorkies (CY) x 4 legs = 196 CY legs
49 x 7 = 343 silk yorkies (SY) x 4 legs = 1372 SY legs

14 girls legs + 196 CY legs + 1372 SY legs = 1582 total legs

Right?! PM me! Lol

I am going to say that there are 10,990 legs on the bus. Am i right?

Each backpack contains 32 legs.
Each girl has 7 backpacks.
So that makes 1568 legs per girl not including her legs.
So add 2 more legs to her that makes 1570.

Now 1570 x 7 girls = 10990.

BethPurk 07-10-2008 08:18 AM
70 legs?

pookiebear 07-10-2008 08:18 AM
10990 is right. Sorry Luvinmyyorkie. I missed your answer back there. You got it right! Sorry there isn't a prize. I love these things. Someone come up with another one. Ya'll got that too quick. I thought this would go on a little longer.

Breezeaway 07-10-2008 08:18 AM
i say 266 legs

That's a really interesting approach for working this out. Never thought about working it that way.

Tnyorkiemom 07-10-2008 08:30 AM
ok 7 girls =14 legs
each back pack has 7 cotton yorkies =24 legs
each cotton yorkie has 7 silky yorkies =24 legs
each girl has 7 back packs
7 x 24 = 168 168 x 7 = 1186
14 + 1186 = 1200

Breezeaway 07-10-2008 08:31 AM
Ok is this how it goes?

7 girls = 14 legs
7 backpacks x 7 cotton Yorks=49x4
49 cotton X 7 silkys =343x4
add
14
406
1372
------
1792

Woogie Man 07-10-2008 08:38 AM
7 girls x 7 backpacks = 49 backpacks.....x 7 yorkies per backpack = 343 yorkies....343 yorkies x 4 legs =1372 legs on the yorkies....+ 14 legs (7 girls x 2 legs each) = 1386 legs the silky yorkies don't count....they're not on the bus

Tnyorkiemom 07-10-2008 08:47 AM

Breezeaway 07-10-2008 08:50 AM
Ok is this how it goes? LOL earlier i put 402 instead of 196

7 girls = 14 legs
7 backpacks x 7 cotton Yorks=49x4=196
49 cotton X 7 silkys =343x4=1372
add
14
196
1372
--------
1582

Shirlthepearl 07-10-2008 09:27 AM
I'd say if we were talking about the girls and the yorkies there's 70, plus the drivers 2.
