Hint: (6 8 2) one number is correct and well placed
(6 1 4)one number is correct but wrongly placed
(2 0 6) two number are correct but wrongly placed
(7 3 8)nothing correct
(7 8 0) one number is correct but wrongly placed

Answer 1

The code is (0 4 2).

Step-by-step explanation:

A numeric has three digit key

(7 3 8) nothing correct --- So, the digits are not 7, 3, 8

(7 8 0) one number is correct but wrongly placed-- So, digits are not 7, 8. One of the digit of the key is 0.

(2 0 6) two number are correct but wrongly placed --- So, 6 cannot be our digit. So, two numbers are 2, 0.

(6 8 2) one number is correct and well placed--- 2 is one digit and well placed.

(6 1 4) one number is correct but wrongly placed--- 4 is another digit.

First digit of the code = 0

Second digit of the code = 4

Third digit of the code = 2

Hence, the code is (0 4 2).
