1st Case:if 'A' is wrong,then answer is none
2nd case:if 'B' is considered as wrong,then obviously 'C' is correct,which tells that "Door B leads to ghost House".But we considered "B doesn't lead to ghost house".Both 'B' & 'C' contradicts this assumption.Hence, 'B' & 'C' cannot be wrong. Only 'A' can be wrong.So answer:None

lets consider door A is wrong then A leads to ghost
on door B written is it leads to ghost
and on door c it is written door B leads to ghost house,henc C leads to freedom
in the same way assume B is wrong,means lead to freedm but on door c written door B leads to ghost house,it is contradiction
last case if we assume C is wrong,the written on door B is also becoming wrong
so our ansr is C lead to freedm which comes from 1st case where we assume A is wrong

one of the given statement is wrong. if door A leads to freedom it is true and other 2 doors also true so A cannot be a door leads to freedom.
if we take A as wrong the other two are which says door B leads to ghost house.
so we have A and B leads to ghost house then the other leads to freedom.hence the answer is C which leads to freedom.

amit  (8 years ago)

consider all the statement one by one-
if Statement A is wrong -it means it doesnot leads to freedom,and as only one statement can be wrong Statement B n C r correct nd both of them leads to ghost house.
statement B & C are relational so if one is wrong then other automatically gets wrong. so none of the answer leads us to definite solution ....
So none will be the answer

Case 1: A, B are true. In this case, Statement C also correct. So contradiction.
Case 2: B, C are true. In this case, B leads to ghost house and C confirms it. Now A is wrong. So door A does not lead to freedom. So Door C leads to freedom.
