the 3 slaves cant open the door this way.......


As far as mechanics go, they can. They all would have a key that was identical with a cylinder shaft, a flap on one side to twist and another flap that goes in the the lock to turn the mechanics. the lock would have to have an extra large cylinder hole to accommodate the three keys as they would have to be turn in unison. It is a completely viable answer. No one said what type of lock it was. So I went ahead and used a lock from the far past that only required something that fit in the whole and move the internal mechanics. I will from here on assume they are using modern locks.

In this way you are distributing the parts of key to the slaves while the question says that the king distributed the keys to the locks of treasure to the slaves

From my interpretation of your problem, at least three slaves should be required to open the treasure. How are you going to distribute 3 keys among four slaves so any three will have a full set but no two will have a full set? If your answer is to give slaves 1, 2 and 3 a key each and not give any keys to slave 4, then you have changed the problem since slaves 4 with any other 2 could not open the treasure.

I interpreted the question the same way, that ANY combination of 3 slaves should be able to open the door.
If this were the problem, then I wonder what the answer would be?

My method has two keys (divided up: vizier+slave[key A], 3 slaves[key b]) and one lock. The riddle says the "king protected his treasure by giving the keys (I did figure in two keys) to the locks of the treasure." It never once states whether or not the keys where divided into pieces. If you want to fault me on semantics then simply say the riddle says locks (plural) so one should automatically be assumed not to be the answer. I admit my answer is wrong because of that fact. It is; however, the simplest answer as to how it would work with one lock. I was to eager to answer my first riddle on here. Next time I will pay closer attention to the riddle itself. Happy solving }: -)

Can't fully visualize this but think it would work

what if the vizer was also a slave. that why he/she would have a key for being the slave and also a key for being a slave. So if the Vizer has 2 keys he/she only needed one more slave to help open the slave room. otherwise the 3 remaining slaves can open the room by themselves. so to answer the question as to how many locks there are, i think the answer is 3.

in this way, 2 slaves can break the chain together... but the question states that it is opened when 3 of them worked together.....
but gud try

sorry but your step is wrong
what you have to do is give every key to a different pair of salves e.g. give key 1 to slaves A and B... keep diving the keys until no more pair of slaves is left... now say you have divided n keys to the slaves.... now give (n+1)th key to every slave and give n keys to the vizier
