Olympic Number Rings
With our Catalina trip, and school underway, itís been hard to find time to follow the Olympic Games. My favorites are the track and field events and the odd events like air gun shooting. Hereís another odd Olympic challenge. The Olympic logo consists of five overlapping rings that form nine separate areas, four of them shared between different rings. The stumper is to place the numbers 1 to 9 in these nine areas so that each complete ring has the same sum. This should be easy with these small numbers! How many different solutions are there?
