Answer 1

Hey.. I think this can be ur answer!!

Let the number be 10y + x
Reversed number = 10x+y

Difference - 10y+x-(10x+y) = 63
9y - 9x =63
y-x= 7

So difference between digits of the number is 7

Hope it helps you dear ☺️☺️
Have a great time!!

Answer 2

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
