Liar Number: Logic Puzzle

Four clues. One of them is a lie. Work out which, and find the hidden number. Every puzzle is generated fresh and always has exactly one answer.

"Greater than 30." "Odd." "Digits add up to 9." "Not 50." — exactly one of these is a lie. Combine the true clues and find the hidden number.
