MAGIC SQUARE: Calculate A+B+C
The aim is to place the some numbers from the list (17, 18, 19, 20, 21, 22, 40, 42, 44, 62) 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 ba14c - 36944 = 432a3 find number abc. Multiple solutions may exist.
Find the right 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.
Having a Beer
On the same day the following week he is back and does the same thing with the three beers. This goes on for a month or two. The bartender is getting curious. The next time the man comes in, the bartender says, "I don't mean to be nosy, but why do you drink from three beers at one time?"
The man says, "When my two brothers and I lived close, we would go to the bar every week and have a beer together. Now we are all married and have moved far away. We all agreed that wherever we are, every week, we will each go to a local bar and have three beers to remember old times."
The bartender nods and goes on. The man finishes his three beers and leaves. A month later the man comes in and orders only two beers. He takes a drink from one... sets it down. Takes a drink from the second beer... sets it down, and repeats this process until the two beers are gone. This goes on for about a month and the bartender gets curious. The next time the man is in the bar, the bartender inquires, "I don't mean to be nosy, but what happened? Did one of your brothers pass away or something?"
The man says, "Oh, no, nothing like that. It's just that my wife said that I couldn't go to the bar and drink anymore... but she didn't say anything about my brothers."
Calculate the number 489
NUMBERMANIA: Calculate the number 489 using numbers [9, 9, 4, 5, 97, 992] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
A.A. GriffithDied 13 Oct 1963 at age 70 (born 13 Jun 1893).Alan Arnold Griffith was a British aeronautical engineer. During the late 1920s, A.A. Griffith and F. Whittle independently made the first practical proposals for the use of gas turbine engines in aircraft. Griffith concentrated on developing an axial flow compressor, and in 1929 he proposed a gas turbine engine driving a propeller, the so called turbo-prop engine. Earlier, in 1917, with G.I.Taylor, he published a pioneering article on the use of soap films in solving torsion problems. In 1920, he published a seminal article on the theory of the brittle fracture. At Rolls Royce (1939-60) he designed turbojet engines, and in the 1950s, vertical take-off aircraft. He developed the remarkable "flying bedstead" which first flew in 1954. |
