It said in the problem that the sum of the final answer is and even number. Then I also read that the number in the one's place is twice the number in the tens place so the number has to be a 2 digit number lesson than 25 but greater than 9. They also had to given even sum.

So then I listed all the numbers:

10, 11, 13, 15, 17, 19, 20, 22,24
The only number that has the one's digit two times the number in the ten's place is 24 . So my final answer is 24.
