MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (20, 22, 24, 28, 30, 32, 52, 54, 56, 79) 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.
Find number abc
If b64a3 + 647a6 = a6aacb 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.
Circle Flies
An old farmer got pulled over by a young state trooper for speeding. The trooper, fresh on the job, decided to throw his weight around and started lecturing the farmer about his speed. He did his best to make the farmer feel uncomfortable but eventually got around to writing the ticket. As he wrote, he had to swat at several flies that were buzzing around his head.
"Having some problems with circle flies there, are ya?" asked the farmer.
The trooper stopped writing the ticket and looked up. "Well yeah, if that's what they are," he said. "I never heard of circle flies, though."
"Oh, they're pretty common on farms," said the farmer. "We call 'em circle flies because they're always circling around the back end of a horse."
"I see," said the trooper as he continued writing the ticket. All of a sudden, he stopped and looked up at the farmer. "Hey...wait a minute, are you trying to call me a horse's ass?"
"Oh no, officer," replied the farmer. "I have far too much respect for law enforcement and police officers to even think about calling you a horse's ass."
"Well, that's a good thing," said the trooper as he resumed writing the ticket.
After a long pause, the farmer continued. "Hard to fool them flies, though."
Calculate the number 679
NUMBERMANIA: Calculate the number 679 using numbers [1, 2, 7, 2, 76, 599] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
Alfred Day HersheyDied 22 May 1997 at age 88 (born 4 Dec 1908). American biologist who, along with Max Delbrück and Salvador Luria, won the Nobel Prize for Physiology or Medicine in 1969. The prize was given for research done on bacteriophages (viruses that infect bacteria). This was the famous “blender experiment”(1956). Hershey used an isotope- labeled phage to to infect a bacterial colony and begin to inject their genetic material into the host cells. Then he whirred them in a Waring Blendor to tear the phage particles from the bacterial walls without rupturing the bacteria. Upon examining the bacteria, Hershey found that only phage DNA, but no detectable protein, had been inserted into them. This showed that the DNA was sufficient to transfer to the bacteria all the genetic information needed to produce more phage. |
