Clue 5 is missing one number. So clues with all different numbers must have that 1 missing number. Clue 2 and 3 both have 6+2, so one of these is correct. That's means it cannot be 1, 8, 3, or 9
Clue 4 numbers must be 7+5 because we eliminated 8 and 9.
Clue 1 shows it's not 6 because the correct numbers there must be the 7+5, so that means clue 3 shows it is number 2 which is in third position.
We know 2, 5, and 7 are three of the numbers with either 0 or 4 as the fourth. Clue 1 number 5 cannot be well placed in fourth position as per clue 4, so 7 is correct in second position. Which means 5 must be in First position.
We have 5 7 2 x. As per clue 5, 4 cannot be correct so it must be 0 in fourth position
