Answer: 32

Explanation:

The only numbers that can have 2 digits and two of which equal to five can only be:

3+2

2+3

4+1

1+4

So the numbers are: 41,14,23, and 32.

41-9=32

14-9=5

23-9=14

32-9=23

Since the question is asking for the number who’s difference is the reverse of one of the numbers. The only possible answer is 32 because 32-9= 23. (23 is the reverse of 32)
