I am thinking of a two-digit number in which the sum of the digits is 9 and the number is even. These clues alone do not create one answer. Add one more clue so that there is only one answer.
Both digits are divisible by 2. The difference of the digits is 2. Both digits are the same. Both digits are divisible by 3. One digit is even, and the other digit is odd.
