 I got it but it made me think. Very good teaser, I like to see a new math teaser now and then. Thanks.

 I guessed 60 buses. Math isn't my strong suit.

 Nice brainsmoker...I was also thinking 60, then remember the other 12. Try to use the calculator only confused my thinking. But thanks anyway.

 Never was any good with math problems. Not my "cup of tea".

 I thought for sure I had this one, but no, I also didn't take the extra ones into account. I don't in general like Math Teasers, that's just me, it's not my strongest skill, although I respect Mathematics A LOT!!!!! One thing that's not a critique of the teaser at all, when I'm on the PC, I don't have any place to work a prob. out on paper with a pencil, and it doesn't help much to try to do it on notepad or the PC calc., so that's another reason I'm not crazy bout them, but that's OK, THANKS for the teaser!

Somehow I got that without the calculator. My lucky day!

 I still don't get it. A print out of the formula would have been nice for a math illiterate like me.

 it was ok, but i think math questions are a little less creative and.... not very fun. it was put together very well, but i dont think it belongs on braingle, maybe like a saxon math book or something.

 That was a great one!! I LOVE math! It's my FAVORITE subject! I would love it if there were more math problems, especially ones that make you think (which this one did).

 Love the math! This actually can be solved quite easily without paper or a calculator:
Because incresing the current garge space by 40% allows for 24 additional buses, 40% of the garage space = 24. So 10% of the garage space = 6 (dividing by 4). Therefore 100% of the garage space = 60 (multiplying by 10). This means that the current fleet is comprised of 72 buses.

 this is what i did
24/x = 40/100
2400 = 40x
60 = x
60 + 12 = 72

 I have to say I was very touched by the story of poor shawneeo who isn't able to use a pencil and paper at the same time as a PC. That must really suck.

 Good One.
40% of the Original # is the 24.
Original # times 40% = 24.
Original # = 24 / 40% (or .40).
Original # = 60.

 Oops, forgot to add:
Original # plus 12 = 72!

 UCH! My brain hurts!!!
I tried to come up with a mathematical way to figure this, but I guess my algebra training is in my toodistant past. ThanxaMILLION to you "MATH MAJORS" for showing us how you did it! Maybe next time ...

 I also enjoy some math teasers. This was very good. Thank you.

 I was disappointed with this one (too easy). One of my granddaughters asked me to teach her algebra after the third grade, and she could solve this one.

 I guess my Math is in need of re learning! So send more of these for me to re learn! I didn't have time for my poor brain to solve this one today but, probably would have sooner or later!

 Just basic simultaneous equations... took a whole minute and a half this time to work it out. The only bit that invovled me thinking was when i put the question from words into 2 simultaneous equations. y is the garage space in buses that can be fitted into it and x is how many buses it currently owns and the answer. the 2 equations are... y = x  12 and 1.4y = x + 12. From these simulatenous equations you can see that y is 60. Therefore the garage space is 60 buses that can be fitted while x is 72. Therfeore, there are 72 buses overall...

 I don't really get it right now. This is what I'm thinking
Okay, if 12 have to be stored outside and then there will be room for 24 with the addition, that means that 12 busses are only 20 percent of all the busses. 12x5=60, and since you don't have the other 12 busses yet, you don't currently own 72.
Okay that's what I'm thinking right now but hey, I'm only in 7th grade so I'm not great at math. If someone would please explain it to me, that'd be awesome!!

 Loved it  brought out the old 'algebra' brain. And we thought we'd never use this stuff in real life.
My formula was 1.4X = X + 12 + 12 (although I almost forgot the additional 12 that were outside).
Thanks for making my brain work!

 My mom also made the same mistake that most of you made... or almost made. She forgot to add the aditianal (please correct me if I spell the previous word wrong!!!) 12 busses. I agree with that person that said it was easy and could be done without pencil, paper, or calculator. Sorry, I don't have very good short term momory. 
octavian420

 lindquist 25  you're absolutely right that the garage can house 60 buses. you have to remember, though, that the garage is full with 12 more buses sitting outside  so you currently have 72. when you expand the garage and add an additional 12, you'll have 84 buses total.
no biggie  seems a lot of people forgot to add the 12 buses back in

 I was brain dead. Normally I could have figured this out but somehow the more I figured the more confused I got. Finally just quit and looked at the answer. Made sense then so maybe I will be able to use my algebra next time. I used to be really good at it. Sorry! Nice job tho.

 Ha! Ha! Ha! Ha! Word problems are always the worst. My grandson is in the second grade and he figured it out before I did. Good one. Do more.

 A simple teaser, very cleverly worded! The no. 12 appears twice in the problem, and this is a deliberate red herring to confuse solvers. A good one. Loved it.
