1. How are you supposed to get 19 or 20 by adding two digits together? Are you implying that noone ever enjoyed Desperate Housewives or Ghost Whisperer?

2. The only possible result is 9. This is easy to prove.
If you write a function of x where x is the number you choose between 1 and 9 and simplify it, it will look like this:
choose a number
x
multiply by 3
3x
3x + 3
multiply by 3 again
3(3x + 3)
simplify
f(x) = 9(x + 1)
Obviously (x + 1) is a random number beetween 2 and 10 and we know that if we multiply a number on that space by 9 the first number will be an rising row and the second one a descending row.
18
27
36
45
54
63
72
81
90
So if we call the first number a, the second number b and x +1 will be k then it will look like this:
a = k-1 = x+1-1 = x
b = 10-k = 10-(x+1) = 9-x
then the final step is
y = a+b = x+9-x = x
y = 9
