Seven International Hostages are lined up in a row .Some are standing or sitting ,

facing backward or forward.All were blindfolded with different colored duct tapes 

and ordered not to move. None has any information about the other hostages.

 

The terrorist leader announced to the nationals before him on the speakers that.. 

they shall all be released if they all can guess  their blindfold's color correctly 

which are  in the order as ff :  Red  Orange Yellow  Green  Blue  Violet   White 

                                            

Chi   has  2 hostages facing backward on his right, 3 sitting down on his right. 

Jap  has  2 hostages facing forward on his left, 3 standing up on his left                     

Fra   has  1 hostage facing backward on his right, 3 standing up on his left.                                           

Rus  has  3 hostages facing backward on his left, 2 sitting down on his left.                        

Eng  has  2 hostages facing forward on his right, 3 sitting down on his right.                      

Ger  has  2 hostages  facing forward on his left, 1 standing up on his right.                  

Spa  has  2 hostages facing backward on his left, 2 standing up on his left

 

In 60 seconds 1 hostage should raise both his  tied hands then will be pulled

behind the row and  will be shot in the head right on the spot in case he fails

to shout the correct color of his blindfold .The other  nationals  will share the 

same fate. If he is right, all the others should not fail or else everyone is going 

to die. If none of them will guess in a minute all will remain hostages..

 

Who would first raise his hands? 

[jhawk]

Eng shouts RED

[TimeSpaceLightForce]

Eng shouts RED

 Too risky!Not him.

Glad I missed that tour bus! I'm vague on what the prisoners know to begin with. I believe the following is true, please correct me if I'm wrong.

 

Here's what WE know:

(1) the prisoners are occupying 7 positions in a linear formation (although each is individually facing in any direction, given in the OP)

(2) each prisoner is wearing a different colored blindfold

(3) reading from one end of the line to the other, the colors are ROYGBVW

 

What do the prisoners know?

(1) Do they know they are in a line?

(2) Do they know where they are in the line?

(3) Do they know the orientations of their immediate neighbors?

(4) Do they know the colors of their neighbors' blindfolds

(5) Do they know which end of the line wears R?

 

I'm presuming that 3,4, and 5 are No.

What about 1 and 2?

[CaptainEd]

There's a lot I don't understand, just in terms of terminology.

 

As an example, OP says that "Chi   has  2 hostages facing backward on his right, 3 sitting down on his right. "

 

Am I to believe that there are EXACTLY 2 hostages facing backward on his right, and any other hostages on his right are facing forward?

Or that there are AT LEAST 2 hostages on his right facing backward?

 

I'm presuming that this gives me no information about how many backwards-facers are to Chi's Left.

Here's what WE know:

(1) the prisoners are occupying 7 positions in a linear formation (although each is individually facing in any direction, given in the OP)

(2) each prisoner is wearing a different colored blindfold  - 4 inches duct tapes

(3) reading from one end of the line to the other, the colors are ROYGBVW - left to right when looking at the row

 

What do the prisoners know? or heard

(1) Do they know they are in a line? - they did

(2) Do they know where they are in the line? -they figured it out

(3) Do they know the orientations of their immediate neighbors?- they did 

(4) Do they know the colors of their neighbors' blindfolds? - no unless informed

(5) Do they know which end of the line wears R? - no unless unless informed

 

I'm presuming that 3,4, and 5 are No.

Spoiler for Thank you, a little more, please

I gather there is an observer who is looking at the row, and sees it from Observer's Left to Right. And, from what you said, the person on Observer's far left is wearing Red.

(1) When you say that "Chi has two facing backward on his right", does "backward" mean "facing away from the observer", or does it mean, "facing the opposite of Chi"?

(2) In the same case, does "on his right" mean "to the same side of the line as Chi's right hand" , or does it mean "to the same side of the line as Observer's right hand" [ I assume it means Chi's right hand )

(3) Do the captives know that the person on Observer's far left is wearing Red?

Spoiler for Perhaps

The hostage from China says he is wearing green?
