The number is 36
47 Impossible problem!
If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.
Since there are only five different digits, a 6-digit number can only be generated if a digit can be repeated. If digits can be repeated, the smallest 6-digit number is 111111.
The original number is 58.
45 and 54
To total 17 the two digits must be 8 and 9! The original number was 98.

the answer is 25 and then if you reverse that it is 52
