    First, just think of the ones digits. Any number that has a units digit of 2, for example, will produce a units digit of 1 or 6 when divided by 2. 4s will produce 2s or 7s, 6s will produce 3s or 8s, 8s will produce 4s or 9s. The only one that’s gonna work for you are 0s, which will produce 0s or 5s. And there’s your breakthrough. The only integers that are gonna work are gonna be the even hundreds. and hence is your ans..
