Step-by-step explanation:
394
Hence the three digit code is 2 9 4
Step 1: Given data
The give five 3 digit code and hints in the given figure.
Step 2: To find
We have to find the 3 digit code to crack ir by the following hints.
Step 3: Finding solution
In a first row, they give 3 digit code 2 9 1.
Hint = One number is correct and in the right place.
Hence in the number 2 9 1 any one number is right and the right place.
In a second row, They give 2 4 5.
Hint = One number is correct but in wrong place.
Hence in the number 2 4 5 any one number is correct but in wrong place.
In a third row, They give 4 6 3 .
Two number are correct and in wrong place.
Hence comparing second and third row hind and number 4 is confirmed in the last place and 6 or 3 have possibility to come first and second digit of the code.
In a fourth row, 5 7 8
Hint = Nothing is correct.
In a fifth row, 5 6 9
Hint = one number is correct but in the wrong place
Hence 5 is eliminated by comparing fourth hint. similarly comparing first hint and fifth hint the place of 9 is fixed in the second place. BY comparing all first place should be 2.
Hence the three digit code is 2 9 4
