2 In the magic square below, each row, column, and main diagonal sum to 100, where K, S, U, O, W, L, I, and N represent (not necessarily distinct) real numbers. Compute N + S + O + L. KSU OWL IN 2009 ANSWER
3 SOLUTION Sum the middle row and middle column 200 = (N +S +O +L) + 2W. Another equation is needed to eliminate W, so sum all of the rows to get 300 = (N +S +O +L) + (K + U + W + I + 2009) = (N + S + O + L) + (K + W + 2009) + (U + W + I) – W = (N + S + O + L) + 200 – W. Thus, 100 = (N + S + O + L) – W. Doubling the last equation and adding it to the first equation, we get 400 = 3(N + S + O + L), so N + S + O + L =. (Note that the answer is independent of 2009!)
