If c3535 - 355bc = abc1 find number abc. Multiple solutions may exist.
The aim is to place the some numbers from the list (19, 21, 22, 24, 28, 30, 65, 68, 74, 89) 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.
Look at the series (17, 51, 204, 1020, 6120, ?), determine the pattern, and find the value of the next number!

Yrjo Vaisala

Died 21 Jul 1971 at age 79 (born 6 Sep 1891).Finnish meteorologist and astronomer regarded as the "father of space research in Finland," As early as 1946, he had suggested that geodetic triangulation at that time being done with rockets or balloons with onboard flashes could better be accomplished by artificial satellites. By the next year he was talking about artificial satellites being used for solar system exploration. In the 1950's he founded Tuorla Observatory and went on to build a tunnel under the hill at Tuorla Observatory to enable making interference measurements to accurately define the length standard for geodesy. He was outstanding in his ability to produce excellent optics for telescopes. Vaisala, together with Liisa Oterman at Tuorla, outpaced the rest of the world in their discovery of minor planets.«

While the bar patron savored a double martini, an attractive women sat down next to him. The bartender served her a glass of orange juice, and the man turned to her and said, "This is a special day. I'm celebrating."

"I'm celebrating, too," she replied, clinking glasses with him.

"What are you celebrating?" he asked.

"For years I've been trying to have a child," she answered, "Today my gynecologist told me I'm pregnant!"

"Congratulations," the man said, lifting his glass. "As it happens, I'm a chicken farmer, and for years all my hens were infertile. But today they're finally fertile."

"How did it happen?"

"I switched cocks."

"What a coincidence," she said, smiling.
