Let A be a subset of {1, 2, . . . , 25} with |A| = 9. For any subset B of A, denote by SB, the sum of the elements in B. Prove that, no matter which elements A consists of, we can always find distinct subsets C and D of A such that |C| = |D| = 5 and SC = SD. (Hint: How many 5-element subsets of A are there? What is the largest 5-element sum?)
