The answer is 46. For the first statement, it shows that the number must be 2 digits. So right there we can cancel out 120 and 8. For the second statement it says the digits must be even. From there, we can cancel out 18, 83. For the third statement, it is written that the 2nd digit must be bigger than the first digit. From then on, we can cancel out all the numbers except for one digit, 46.
