MAGIC SQUARE: Calculate A+B*C
The aim is to place the some numbers from the list (4, 5, 7, 8, 9, 12, 22, 23, 27, 46) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A+B*C.

The Auction
One day a man went to an auction. While there, he bid on a parrot. He really wanted this bird, so he got caught up in the bidding. He kept on bidding, but kept getting outbid, so he bid higher and higher and higher. Finally, after he bid way more than he intended, he won the bid - the parrot was his at last!
As he was paying for the parrot, he said to the auctioneer, "I sure hope this parrot can talk. I would hate to have paid this much for it, only to find out that he can't talk!"
"Don't worry," said the auctioneer, "He can talk. Who do you think kept bidding against you?"
Which is a winning combination of digits?

Otto DielsDied 7 Mar 1954 at age 78 (born 23 Jan 1876).Otto Paul Hermann Diels was a German organic chemist who with Kurt Alder was awarded the Nobel Prize for Chemistry in 1950 for their joint work in developing a method of preparing cyclic organic compounds. His most important work concerned the diene synthesis, in which organic compounds with two carbon-to-carbon double bonds were used to effect syntheses of many cyclic organic substances under conditions that threw light on the molecular structure of the products obtained. This method was developed (1928) in collaboration with Kurt Alder, his student, and is known as the Diels-Alder reaction. Their work proved especially important in the production of synthetic rubber and plastics. |
