Answer 2

• Let the unit place of a digits be x.

                     and tens place digits be  y.

So the no. = 10 y + x

A/Q,   x + y = 8 .........(i)

Again A/Q,  10 y + x + 8 = 10 x + y

               9 x - 9 y = 8

                 x - y = 8/9

This is the concept of such .

But A/Q there is not any such no.

Hope it helps u.
