Greater than 400 and less than 600, so the number has to be in the range 401 through 599. Consequently the hundreds digit is either 4 or 5. If it is 4, then the tens digit has to be 5. 4 plus 5 is 9. Then since 12 - 9 = 3, the number has to be 453. But if the hundreds digit is 5, then the tens digit has to be 6. 5 plus 6 is 11, and since 12 - 11 = 1. Then the number has to be 561.

So either 453 or 561 fits the criteria given.
