Question 25

From the set of numbers from 1 to 99, I choose as many different numbers as I could so that no subset from my chosen numbers has a sum of 100. If I want the sum of all my chosen numbers to be as large as possible, what is the smallest possible number that I can actually choose to be part of the subset?
