Question

Find Three digit code?

Answer 1

The three digit code is 042 .

First take condition - 1 & 2

Here ,Considering 6 as one of the code ,as the per the first condition ,it is well placed .Though it is in the same position in Condition 2 ,it shows wrong placed .Hence, 6 can be deleted from the answer set .

Now Take Condition - 4,

It says that 7,3,8 are not correct. Hence they are eliminated from the code .


Go to condition 3 :

We have already eliminated 6 and left are 0,2 .According to the condition , Two are correct and wrongly placed .So we have got two digits of our code .

Go to condition 5 ;

7,8 are already eliminated from the code .We are left with 0 .It says 0 is correct but not placed well .So position of 0 is not the third spot
From condition 3 ;

We got that 0 is not in middle spot either .Hence 0 is the starting number of the code .

Go back to condition 1 :-

We already eliminated 6,8 .We are left with 2 .The conditions says that it is well placed. Hence 2 is the third digit of our code .

Finally Go to Condition 2 :-

Remember we have only middle digit left to be found .We already eliminated 6 from code .We are left with 1 , 4 .As per the code,the correct digit is wrongly placed .If we consider 1 , it is not wrongly placed .So contradicts the condition .Hence 4 is the digit and its position is middle ...


Finally the code is cracked .


Code - 042 .
