2012 Gauss Contest Solutions Page 6 19 In an ordered list of ve integers, the median is the number in the middle or third position Thus if we let the set of integers be a;b;c;d;e, ordered from smallest to largest, then c = 18
2012 Euclid Contest Solutions Page 4 (b) Let n= (3a+ 6a+ 9a+ 12a+ 15a) + (6b+ 12b+ 18b+ 24b+ 30b) First, we simplify the given expression for nto obtain n= (3a+ 6a+ 9a+ 12a+ 15a) + (6b+ 12b+ 18b+ 24b+ 30b) = 45a+ 90b We then factor the right side to obtain n= 45(a+ 2b) = 3251(a+ 2b) If a+ 2b= 5, then n= 3252 = (3 5)2, which is a perfect square
