Do you like math puzzles?

Try this one
The Two Aeroplanes Math Puzzle

A man recently bought two aeroplanes, but afterwards found that they would not answer the purpose for which he wanted them. So he sold them for $600 each, making a loss of 20 per cent, on one machine and a profit of 20 per cent, on the other. Did he make a profit on the whole transaction, or a loss? And how much?

How did you go?

The Two Aeroplanes Solution

The man must have paid $500 and $750 for the two machines, making together $1,250; but as he sold them for only $1,200, he lost $50 by the transaction

In Dudeney's preface of his books:- Our lives are largely spent in solving puzzles; for what is a puzzle but a perplexing question? And from our childhood upwards we are perpetually asking questions or trying to answer them. He also wrote:- "The solving of puzzles consists merely in the employment of our reasoning faculties, and our mental hospitals are built expressly for those unfortunate people who cannot solve puzzles."

Company Overview:	Piratesmath was set up to Make Math Fun. My daughters were struggling with math. They would say, "its too hard, its boring." Not a good way to enjoy maths. After researching the best ways in learning math, I created piratesmath. Math is Fun, Sharing the Swashbuckling Pirates Secrets of Math created a maths program based on the Swashbuckling adventures of a pirate Captain Abacus. He was able to make Maths fun to learn. As Captain Abacus, I would pose maths Puzzles to stretch her maths skills. These Maths Puzzles built her confidence to tackle any Maths Problem. Laura has a unquenchable thirst for Maths puzzles ,because she thinks there fun, they don't feel like mathematics. Sudoku Maths puzzles have become all the rage. On my train trip home form work, I noticed carriages of people head down immersed in their Sudoku Puzzles. I can't think of a better way of fulling in time on the boring train trip. Laura asked if I could buy her, another newspaper, so she could do the Sudoku. She did like my half scratched copy. Now I just photocopy The Sudoku. The trouble is now her younger sister Celina wants to do the puzzles as well. It's become a competition to see who can find the maths Puzzle from hell. "Dad I Bet you can't do this one?" "What about this one? Aha I got you." Laura's favourite Puzzles were created by Henry Ernest Dudeney "A good puzzle should demand the exercise of our best wit and ingenuity, and although a knowledge of mathematics and of logic are often of great service in the solution of these things, yet it sometimes happens that a kind of natural cunning and sagacity is of considerable value" Henry Ernest Dudeney.
