ANSWER: 0 4 2

The code is 0 4 2

D. 7 3 8 – Nothing is correct – We can rule out these 3 digits from other statements

A. 6 8 2 – One Number is correct and well placed   – Number cannot be 6 as that will make Statement B wrong so number in code is 2 which is correctly placed also(on Position 3)
B. 6 1 4 – One Number is correct but wrong place – 6 cannot be that number as per Statement A, It cannot be 1 also as if number is 1 it can be on either on 1st or 3rd place those are already taken by digits 0 and 2 so only number left is 4
C. 2 0 6 – Two Numbers are correct but Wrong Places – One of digit which is correct is 0 as per Statement E but its place cannot be at second(as per statement C) and third position( as per Statement E) so it can be only one first place, other digit is 2 as per statement A.
E. 8 7 0 – One Number is correct but wrong place – We know 0 is one of digit in code but place for it would be not 3

From statement A, B and E we got our numbers. Statement A gave position for Number 2 . Statement C and E gave position for other 2 numbers.

Statement A ->  X X 2

Statement A, C and E-> 0 X 2

Statement B -> last digit 4 which will come in middle so code would be 0 4 2

Hence the code is 0 4 2
