Let the 2 digit no. be 10x + y
No. obtained by reversing the digits is 10y + x
According to the question :
10x + y - ( 10y + x ) = 63
10x + y - 10y - x = 63
9x - 9y = 63
9 ( x - y ) = 63
x - y = 63 / 9
x - y = 7
So the difference between the digits is 7.
Hope it helps buddy.
Have a good day pal.

according to this 10x + y - ( 10y + x ) = 63
10x + y - 10y - x = 63
9x - 9y = 63
9 ( x - y ) = 63
x - y = 63 / 9
x - y = 7
so x-y =7
10x + y - 10y - x = 63
9x - 9y = 63
9 ( x - y ) = 63
x - y = 63 / 9
x - y = 7
so x-y =7
