Here is the Solution :-
Let the number be 10x + y.
After interchanging it's digits, We get a number : " 10y + x "
Given,
10x + y - ( 10y + x ) = 63
9x - 9y = 63
9 ( x - y) = 63
( x - y) = 7 .
We know that, x, y are the digits. We found x - y = 7 .
So ,The difference between the digits of the number is 7
