If you have not tried its simpler version, try that first click here for Who is the thief puzzle part 1
A horse, a donkey and a camel were stolen.
Three suspects: Robert, Scott and Tommy. All we know that each person stole one animal, but we do not know who stole which. Here are the investigation statements.
Robert: Tommy stole the horse.
Scott: Tommy stole the donkey.
Tommy: They both were lying. I did not steal the horse or the donkey.
Later on, police found out =>
The man who stole the camel told a lie.
The man who stole the horse told the truth.
Can you find out who stole which?
Robert Stole Camel.
Scott stole Horse.
Tommy stole Donkey.
Here first and second statement are contradictory, both can be true together. Also both can not be false as well as it will mean Tommy stole camel and his statement will be true. But as we know the one who stole camel told a lie so it cant be.
From above we can say Tommy either stole a horse or a donkey.
Lets assume Tommy stole the horse, in this case Tommy’s statement will be false. But we know the one who stole the horse told the truth so this is contradicting and it cant be correct as well.
So We can say that Tommy stole the Donkey for sure.
As Tommy stole the donkey, Robert’s statement is false and Scott’s statement is true and camel and horse is stolen by these two. We also know that one who stole horse is true and one who stole camel is lying, we can deduce that Robert stole Camel and Scott stole Horse.
