MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (15, 16, 24, 27, 28, 36, 37, 63, 64, 72) 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.

Free Drinks For Everyone
One night, a drunk comes stumbling into a bar and says to the bartender: "Drinks for all on me including you, bartender." So the bartender follows the mans orders and says: "That will be $36.50 please." The drunk says he has no money so the bartender slaps him around and throws him out.
The next night the same drunk comes in again and orders a drink for everyone in the bar including the bartender. Again the bartender follows instructions and again the drunk says he has no money. So the bartender slaps him around and throws him out.
On the third night he comes in, the drunk orders drinks for all except the bartender. "What, no drink for me?" replies the bartender. "Oh, no. You get violent when you drink."

Which is a winning combination of digits?
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot.

Louis EssenBorn 6 Sep 1908; died 24 Aug 1997 at age 88.English physicist who invented the quartz crystal ring clock and the first practical atomic clock. These devices were capable of measuring time more accurately than any previous clocks. He built a cesium-beam atomic clock, a device that ultimately changed the way time is measured. Each chemical element and compound absorbs and emits electromagnetic radiation at its own characteristic frequencies. These resonances are inherently stable over time and space. The cesium atom's natural frequency was formally recognized as the new international unit of time in 1967: the second was defined as exactly 9,192,631,770 oscillations or cycles of the cesium atom's resonant frequency, replacing the old second defined in terms of the Earth's motion. |
