description:
Some people believe that there are three cycles in a person's life that start the day he or she is born. These three cycles are the physical, emotional, and intellectual cycles, and they have periods of lengths 23, 28, and 33 days, respectively. There is one peak in each period of a cycle. At the peak of a cycle, a person performs at his or her best in the corresponding field. Since the three cycles have different periods, this problem asks students to determine when a triple peak occurs (the peaks of all three cycles occur in the same day) for any person.
