Expert Answer
Consider the number 67.

Number after reversing the digits is 76.

Difference = 76 - 67 = 9

Clearly the difference is divisible by 9.

Again, consider the number 39.

Number after reversing the digits is 93.

Difference = 93 - 39 = 54 = 9 x 6

Clearly the difference is divisible by 9.
