"The sum of two consecutive number is 13"
A quick mental check shows the two numbers must be 6 and 7
Don't know what you mean by reversing a single digit number.
Perhaps the question should have said:
The sum of the digits of a number is 13.
If the digits are reversed, then the difference between the new number
and the old number is 9
the answer to that would be 67
