If I understand your question, then there are:

33 - 25 + 1 = 9 different positive values of x:

25, 26, 27, 28, 29, 30, 31, 32, 33. Each one of these numbers has exactly 2 positive two-digit multiples:

Example: 25 has 50 and 75. 26 has 52 and 78. 27 has 54 and 81......and so on for all 9 of them.
