MAGIC SQUARE: Calculate A*B-C
The aim is to place the some numbers from the list (4, 6, 8, 10, 12, 14, 16, 26, 28, 30, 48) 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 1a29c + c82b1 = 52a9a 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.
How To Save Money!
Three engineers and three accountants are traveling by train to a conference. At the station, the three accountants each buy tickets and watch as the three engineers buy only a single ticket.
"How are three people going to travel on only one ticket?" asks an accountant.
"Watch and you'll see," answers an engineer.
They all board the train. The accountants take their respective seats but all three engineers cram into a restroom and close the door behind them. Shortly after the train has departed, the conductor comes around collecting tickets. He knocks on the restroom door and says, "Ticket, please."
The door opens just a crack and a single arm emerges with a ticket in hand. The conductor takes it and moves on.
The accountants saw this and agreed it was quite a clever idea. So after the conference, the accountants decide to copy the engineers on the return trip and save some money (being clever with money, and all that). When they get to the station, they buy a single ticket for the return trip. To their astonishment, the engineers don't buy a ticket at all.
"How are you going to travel without a ticket?" says one perplexed accountant.
"Watch and you'll see," answers an engineer.
When they board the train the three accountants cram into a restroom and the three engineers cram into another one nearby. The train departs. Shortly afterward, one of the engineers leaves his restroom and walks over to the restroom where the accountants are hiding. He knocks on the door and says, Ticket, please."

Joshua Lionel CowenDied 8 Sep 1965 at age 85 (born 25 Aug 1880).American inventor of electric model trains who founded the Lionel Corporation (1901), which became the largest U.S. toy train manufacturer. At age 18, he had invented a fuse to ignite the magnesium powder for flash photography, which the Navy Department bought from him to be a fuse to detonate submarine mines. He designed an early battery tube light, but without practical application. (His partner, Conrad Hubert, to whom he gave the rights improved it and founded the Eveready Flashlight Company.) At age 22, he created a battery-powered train engine intended only as an eye-catcher for other goods in a store window. To his surprise, many customers wanted to purchase the toy train. Thus he started a model railroad company.« |
