Like I said, we're going to multiply this by 10. So this becomes 10x and this becomes as it is 9 minus 1 plus X the final number after interchanging the digits with 10 X Plus 9 minus X. This is the let's go back to our question when we interchange the disc. It is found that the resulting new number.
