MAGIC SQUARE: Calculate A*B+C
The aim is to place the some numbers from the list (15, 16, 22, 24, 25, 31, 36, 37, 43, 61, 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 84b24 - 4a804 = c4820 find number abc. Multiple solutions may exist. 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. 
Not Afraid
A few minutes before the church services started, the congregation was sitting in their pews and talking. Suddenly, Satan appeared at the front of the church.
Everyone started screaming and running for the back entrance, trampling each other in a frantic effort to get away from evil incarnate. Soon the church was empty except for one elderly gentleman who sat calmly in his pew without moving, seemingly oblivious to the fact that God's ultimate enemy was in his presence.
So Satan walked up to the man and said, 'Do you know who I am?'
The man replied, 'Yep, sure do.'
Aren't you afraid of me?' Satan asked.
'Nope, sure ain't.' said the man.
Don't you realize I can kill you with one word?' asked Satan.
Don't doubt it for a minute, ' returned the old man, in an even tone.
'Did you know that I can cause you profound, horrifying agony for all eternity?' persisted Satan.
Yep,' was the calm reply.
'And you're still not afraid?' asked Satan.
'Nope,' said the old man.
More than a little perturbed, Satan asked, ' Why aren't you afraid of me?'
The man calmly replied, 'Been married to your sister for 48 years.'
Calculate the number 1846
NUMBERMANIA: Calculate the number 1846 using numbers [3, 7, 5, 1, 36, 910] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once. Neanderthal originsIn 1997, the first sequencing of pieces of DNA extracted from a Neanderthal-type specimen was published in the journal Cell, by a team of scientists led by Svent Pääbo.In the groundbreaking study, mitochondrial DNA was amplified from a sample (a small piece of the arm bone) from the first Neanderthal man found (1856). “The Neanderthal sequence falls outside the variation of modern humans.” The results suggested that from their common origin (“African Eve”), Neanderthals split off from humans a little over 550,000 years ago as a separate species and “went extinct without contributing mtDNA to modern humans.” (Using population models, Pääbo, more recently estimated that Neanderthals could have contributed up to 25% of their genetic makeup to modern human, but likely much less.)«[Ref: Cell (11 Jul 1997), 90, No.1, 19-30.] |
