You are traveling in a train, there are only 4 other people in your berth.
They are named A, B, C and D . Your wallet is stolen. Assume that the wallet was stolen by one of those 4 people and that only 3 of them lie.
Here are their statements:
A: B stole the wallet.
B: C didn’t steal.
C: I didn’t steal.
D: C stole your wallet.
Who actually stole your wallet?
C
Logically, only A, B and C can be lying.
The puzzle – to be precise, the ‘assumption’ part – needs rephrasing. “only 3 of them lie” means that only 3 of them has a history / habit of lying, but it doesn’t imply that they ALWAYS lie. We have to do the additional bit of assumption to conclude the answer. Otherwise, the information provided is insufficient to reach a conclusion.
Have ur assumption wherever required,
Like here 3 of them always lie
