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."

The revised Amusements in Mathematics

Henry Ernest Dudeney was born 10 April 1857 in Mayfield, Sussex, England and died of throat cancer, 24 April 1930 in Lewes, Sussex, England

He was an English author and mathematician, specialising in logic puzzles and mathematical games. He was known as one of England's prominent
creators of puzzles.

Henry Ernest Dudeney grew up in a household Mathematicans. His grandfather was a shepherd who taught himself mathematics and astronomy. The Maths dominated his life, so much he left the sheep and became a schoolmaster in Lewes. henry father was school teacher. Henry's grandfather taught him to Chess at an early age, and he continued to playing throughout his life. This love of Chess led Dudeney to creating Chess problems and maths puzzles, by the age of 9 he getting his puzzles published in his local newspaper.

Although maths was his passion, he never attended college, he studied maths & history in own time.

Dudeney wrote:
"The history of mathematical puzzles entails nothing short of the actual story of the
beginnings and development of exact thinking in man."

Dudeney worked as a clerk in the Civil Service from the age of 13 but continued to study mathematics
and chess.Dudeney's first puzzle contributions were submissions to newspapers and magazines, often under
the pseudonym of "Sphinx." his earlier work was a collaboration with the American puzzlist Sam
Loyd; in 1890, they published a series on article in the English penny weekly Tit-Bits.

in 1917 Dudeney wrote Amusements in Mathematics. 430 math brain teasers.
