Attention Logic Puzzle Lovers - Who wants to Crack the Code?

1: 682 one digit is right and in the right place

2: 738 all digits are wrong

3: 206 two digits are right but both are in the wrong place

4: 614 one digit is right but is in the wrong place

5: 780 one digit is right but in the wrong place

Start with statement 2, eliminate 7, 3 and 8 as correct digits.

This leaves statement 5 with only the 0 (but in the wrong place)

Statement 3 tells us that 206 has 2 digits, but they're both in the wrong place.

So now... we know that 0 is correct, but it can't be in the middle spot (since 206 is wrong)

nor can it be in the last spot (since 780 is wrong). The first number MUST be 0

Statement 1 now tells us that (682 has 1 digit right and in the right place.

It can't be the 6 (since the first number is 0), it can't be the 8 (since 738 are all wrong)

So the last number MUST be 2.

Statement 4 tells us that one digit is right but in the wrong place. We know 6 is wrong;

since statement 1 has only has 1 right number and it's the 2. So this leaves the 1 and the 4.

But it CAN'T be the 1 because then the 1 would be right AND in the right place. So we know

the only correct number is in the wrong spot. 4 is correct but belongs in the middle possition

so code is 042
