This could be a General Mathematical Thinking Thread, cause there to many problems.
Leaving the Lateral Thinking Threads for a while ...
Here´s mine:
You've been asked to buy 100 squeegies, using 100 dollars to do so. You may buy no more or less than 100 squeegies, and the total price must be exactly 100 dollars. There is no sales tax. Red squeegies cost $6.00. Yellow squeegies cost $3.00. Blue squeegies cost $0.10. How many of each must you buy?

描いた夢は叶わないことの方が多い
秀れた人を羨んでは自分が嫌になる
浅い眠りに押し潰されそう夜もある
優しい隣人が陰で牙を向いていたり
惰性で観てたテレビ消すみたいに生きることを時々辞めたくなる
人生は苦痛ですか 成功が全てですか
僕はあなたにあなたに ただ逢いたいだけ
信じたい嘘 効かない薬 帰れないサヨナラ
叫べ叫べ叫べ 逢いたいだけ

Re: Mathematical Thinking I, II, .... (previously Puzzle: Ma
Since your solution worked, I would say that your answer is correct! And because of no response from Holmes by now, I think a new quiz can start!googleearth wrote:Spoiler:

So, you don't find one, googleearth?
Well, then I post the next one if it's okay for you all...
So, here it is:
"You've got 60 square concrete slabs. And with this 60 slabs you shall make a rectangle with a minimal circumference. Can you tell what side-lengths the rectangle have? Explain your answer!"
(Hope you get the quiz...

Re: Mathematical Thinking I, II, .... (previously Puzzle: Ma
My turn, say? Couldn't think of any good one now, but here's one I remember the most 
A woman sold a number of egg.
In her first sale, she sold half of the eggs AND half an egg.
In her second sale, she sold half of the remaining eggs AND half an egg.
In her third sale, she sold half of the remaining eggs AND half an egg.
After her third sale, no egg remained.
Q: What is the number of egg before selling?
P/S: If my mind's right this is 7th grade math...I struggled solving it when I was in grade 7 though
...And yeah this kind of math can drag on to the 4th, 5th, etc. sales...

Yeah that's right
It's not a difficult question though
Your turn, I guess?

Ok, here's mine:
Two mathematitians met in the street after a long time without seeing each other.
- Long time no see!
- Yeah, it seems like it was yesterday...
- So, you got married, rigth?
- Yes, and I have 3 beautiful daughters.
- How old are they?
- I'm not telling you their ages, but I'm telling you that the product of their ages is 36 and their sum is 13.
The friend started making calculations and after some time said:
- I need more information
- Sure, the oldest one plays piano.
Rigth after hearing this, the friend said the answer.
How old are the daughters? Explain your answer.
I'm leaving the answer as spoiler, just in case I'm away for a long time (don't look before posting yours
