Answer:
718
Step-by-step explanation:
0,1,2,3,4,5,6,7,8,9
The second line says we cannot have 0,3,5
1,2,4,6,7,8,9
The third line says 157 has 2 numbers correct. We have eliminated the 5 so 1 and 7 are correct
1,2,4,6,7,8,9 1 and 7
The first line says 548 has one number correct so it is either 4 or 8
Line 4 says 806 has 1 number correct so the third number is 8
The three numbers are 1 7 8
Now put them in order ***
Line 1 548 One number is correct so it must be 8 **8
Line 2 tells use nothing about the order
Line 3 tells us that 2 numbers are correct but not in the right places so 1 cannot be 1st so it must be second (3rd is already taken) and there fore 7 must be 1st
