The logic professor posted a notice on his class door: "Class is canceled today on account of spring. We will meet again at 1:00 P.M. three days after two days before the day before tomorrow." What day does the class meet?
The next day. The day before tomorrow: tmrw- +1, the day before it -1, i.e. still the same day the professor dismissed the class. Two days before the...: 2 days before the class was dismissed- -2. Three days after... -2+3 days gain. Meaning the class will meet a day after the class was dismissed.
When the day after tomorrow is yesterday, today will be as far from Wednesday as today was from Wednesday when the day before yesterday was tomorrow. What is tomorrow?
In a university, a professor gave a set of three problems to the three brilliant students of his class. See the image for the questions.
Tomorrow is neither Wednesday nor Thursday.
Yesterday was not Friday or Saturday.
Today is not Thursday or Sunday or Monday.
What day is it today?
