Mr. Greenwich has a clock that chimes on both the hours and the half hours. The clock strikes once for each half hour, once for one o'clock, twice for two o'clock, three times for three o'clock, etc. As Mr. Greenwich walked into his house one day, he heard the clock chime once. A half hour later it chimed once again. A half hour later it chimed once, and a half hour later it chimed once again. Since the clock is working properly, what time was it when Mr. Greenwich entered his house?

Answer: It was just moments after twelve o'clock. He heard the last of the twelve chimes as he walked through the door. He then heard one chime for 12:30, one chime for 1:00 and one chime for 1:30
