Even though there wasn't a number like that, if the problem tells us that there are 100's 1, 100's 2, and 100's 3, then the addition of the digits would be: 100 * 1=100 100 * 2=200 100 * 3=300 This because there are a hundred of each number, whatever it possition would be. So, the addition is equal to 600, and there's not a similar option, so it's: NONE OF THESE
