Find number abc
If 75ccb + cbaca = a0a347 find number abc. Multiple solutions may exist.
What a winning combination?
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.
Duck Hunting
A city slicker shoots a duck out in the country. As he's retrieving it, a farmer walks up and stops him, claiming that since the duck is on his farm, it technically belongs to him. After minutes of arguing, the farmer proposes they settle the matter "country style."
"What's country style?" asks the city boy.
"Out here in the country," the farmer says: "when two fellers have a dispute, one feller kicks the other one in the balls as hard as he can. Then that feller, why, he kicks the first one as hard as he can. And so forth. Last man standin' wins the dispute."
Warily the city boy agrees and prepares himself. The farmer hauls off and kicks him in the groin with all his might. The city boy falls to the ground in the most intense pain he's ever felt, crying like a baby and rolling around on the ground. Finally he staggers to his feet and says: "All right, n-now it's–it's m-my turn."
The farmer grins: "Forget it, you win. Keep the duck."

Cyril PonnamperumaDied 20 Dec 1994 at age 71 (born 16 Oct 1923). Ceylonese-American chemist and exobiologist, who was a leading authority on the chemical origins of life. He built on the work of Miller and Clayton Urey studying chemical reactions in "primordial soup" experiments. Ponnamperuma focused on producing compounds related to the nucleic acids and offered a convincing theory about series of chemical reactions that gave rise to precursors of life on earth. He demonstrated that nucleotides and dinucleotides can be formed by random processes alone. In another achievement, he showed the formation of ATP, a compound critical to the use of energy within a cell. He was also active in the growing field of exobiology, the study of possible extraterrestrial life and studied lunar soil and meteorites.« |
MAGIC SQUARE: Calculate A-B*C
