Statement :
You are playing a game Detective Sherlock and you with your friends are solving a case. However, the way to the solution might be tricky and confusing. Just remember that only one of the statement is TRUE and rest three are FALSE.
1. Jack : “Britney did it”.
2. Britney : “Jack did it”.
3. Selena : “Britney’s telling the truth”.
4. Martha : “Selena’s not lying”.
Solution :
Britney did it.
We will take up every person and analyze the statements over all of them one by one.
Case 1 : Britney did it, then
Statement 1 : TRUE
Statement 2 : FALSE (as Jack did not do it)
Statement 3 : FALSE (as Britney is lying)
Statement 4 : FALSE (as Selena is lying)
Our first guess itself was right but let us confirm our analysis by analyzing the statements over others.
Case 2 : Jack did it, then
Statement 1 : FALSE (as Britney did not do it)
Statement 2 : TRUE
Statement 3 : TRUE (as Britney is not lying)
As per the conditions, three statements had to be wrong but here, we have two statements right which clearly contradict the condition.
Case 3 : Selena did it, then
Statement 1 : FALSE (as Britney did not do it)
Statement 2 : FALSE (as Jack did not do it)
Statement 3 : FALSE (as Britney is lying)
Statement 4 : FALSE (as Selena is lying)
She did not do it as all the statements are FALSE.
Case 4 : Martha did it, then
Statement 1 : FALSE (as Britney did not do it)
Statement 2 : FALSE (as Jack did not do it)
Statement 3 : FALSE (as Britney is lying)
Statement 4 : FALSE (as Selena is lying)
All four statements are FALSE in her case as well thus she did not do it.
Therefore we have proved that Britney did it.
