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.
Calculate the number 2291
NUMBERMANIA: Calculate the number 2291 using numbers [5, 7, 6, 5, 90, 345] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (20, 21, 23, 25, 30, 31, 35, 65, 66, 70) 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 new dads!
I was sitting in the waiting room of the hospital after my wife had gone into labor when the nurse walked out and said to a man sitting there, "Congratulations sir, you're the new father of twins!"
The man replied, "How about that! I work for the Minnesota Twins baseball team." About an hour later, the same nurse entered the waiting room and announced that Mrs. Smith had just had triplets.
Mr. Smith stood up and said, "Well, how do ya like that, I work for 3M!"
When the nurse appeared next, she told the third man that his wife had given birth to quadruplets.
"That's amazing! I work for the Four Seasons Hotel!"
At this point the gentleman sitting next to me let out a little strangled gasp and hurriedly got up, obviously distraught. When I asked him if he was okay, he explained, "I think I need a breath of fresh air." The man continued, "I'm the casting director for 101 Dalmatians."
Find number abc
If 880c7 - bb71a = 5cbb5 find number abc. Multiple solutions may exist.
Germain Henri HessBorn 8 Aug 1802; died 13 Dec 1850 at age 48.Swiss-Russian chemist whose studies of heat in chemical reactions formed the foundation of thermochemistry. He formulated an empirical law, Hess's law of constant heat summation (1840), which states that the heat evolved or absorbed in a chemical process is the same whether the process takes place in one or in several steps. It is explained by thermodynamic theory, which holds that enthalpy is a state function. Chemists have made great use of the law of Hess in establishing the heats of formation of compounds which are not easily formed from their constituent elements. His early investigations concerned minerals and the natural gas found near Baku, and he also discovered the oxidation of sugars to yield saccharic acid.DSB gives dates as 8 Aug 1802 - 13 Dec 1850. EB gives 7 Aug 1802 - 30 Nov 1850.] |
