The code is 718
From Clues 1 and 2 we know that one 5 is not in the code
from Clue 3 we know that 1 and 7 are part of code
from Clue 4 we know that 8 is also in the code.
So the 3 numbers in the code are 8,1 and 7. Now solve for order.
From Clue 1 we know that 8 is the third number
From clue 3 we know that 1 and 7 are in wrong place so we now know that,
7 is frist , 1 is second in code and 8 is third.
So the Code is 718.
