MAGIC SQUARE: Calculate A+B-C
The aim is to place the some numbers from the list (3, 12, 15, 16, 22, 24, 25, 26, 39, 42, 43, 58) 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.
A drunk at the bar
A man walks into the front door of a bar. He is obviously drunk and staggers up to the bar, seats himself on a stool and, with a belch, asks the bartender for a drink. The bartender politely informs the man that it appears he has already had plenty to drink and that he could not be served additional liquor. The bartender offers to call a cab for him.
The drunk is briefly surprised, then softly scoffs, grumbles, climbs down from the bar stool and staggers out the front door. A few minutes later, the same drunk stumbles in the side door of the bar. He wobbles up to the bar and hollers for a drink. The bartender comes over and - still politely if not more firmly - refuses service to the man and again offers to call a cab. The drunk looks at the bartender for a moment angrily, curses, and shows himself out the side door, all the while grumbling and shaking his head.
A few minutes later, the same drunk bursts in through the back door of the bar. He plops himself up on a bar stool, gathers his wits, and belligerently orders a drink. The bartender comes over and emphatically reminds the man that he is drunk and will be served no drinks. He then tells him that he can either call a cab or the police immediately.
The surprised drunk looks at the bartender and in hopeless anguish cries, "Man! How many bars do you work at?"
