Answer 2

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
