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. Calculate the number 5159
NUMBERMANIA: Calculate the number 5159 using numbers [7, 4, 6, 6, 67, 433] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once. Find number abc
If bba48 - b5c57 = cc9c find number abc. Multiple solutions may exist. 
The Statue
A woman was in bed with her lover when she heard her husband opening the front door.
"Hurry!" she said. "Stand in the corner." She quickly rubbed baby oil all over him and then she dusted him with talcum powder. "Don't move until I tell you to," she whispered. "Just pretend you're a statue."
"What's this honey?" the husband inquired as he entered the room.
"Oh, its just a statue," she replied nonchalantly. "The Smiths bought one for their bedroom. I liked it so much, I got one for us too."
No more was said about the statue, not even later that night when they went to sleep. Around two in the morning the husband got out of bed, went to the kitchen and returned a while later with a sandwich and a glass of milk. "Here," he said to the 'statue', "eat something. I stood like an idiot at the Smith's for three days and nobody offered me so much as a glass of water".
Which is a winning combination of digits?

White circles indicate the number of hits on the wrong spot. Marcel Gilles Jozef MinnaertDied 26 Oct 1970 at age 77 (born 12 Feb 1893).Flemish astronomer and solar physicist who was one of the pioneering solar researchers during the first half of the 20th century. Applying solar spectrophotometry, he was one of the first to make quantitative measurements of the intensity distribution inside Fraunhofer lines, and interpret from them information about the outer solar layers. His range of study also included comets, nebulae and lunar photometry. During the time he was director of the observatory at the University of Utrecht, (1937-1963) he created a modern astronomical institute to study solar and stellar spectra with resources including a solar telescope, spectrograph, photometer, and mechanical workshop. Minnaert also maintained a strong interest in the education of physics teachers, and as a univeristy professor gave clear, enthusiastic and well-prepared lectures.«. |
Calculate the number 5800
NUMBERMANIA: Calculate the number 5800 using numbers [1, 6, 3, 2, 42, 817] 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 (3, 21, 26, 27, 31, 32, 34, 37, 48, 64, 69, 74) 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
