George Boolos puzzle...(wordings are changed)

Once you reach to a remote small village in a jungle, and you come accros three men.

One of them always speak truth

One of them akways speaks lie

One of them speak either truth or lie randomly 

Now your task is to find out the idendity of three men by asking three  questions,one to each. 

Problem is queations should be ansewrable as Yes or No

 They can undertand your laungage,but you do not know  which is ' Yes 'or which one is 'No'., by listining them

You can ask more than one questions to each one.

....     .......  ...  ...

Now probable  solution as worked out by me...(not tested by anyone)

Let three persons are

X......always speaks truth

Y.......always speaks lie

Z.......Random truth or lie

Let sound of 'Yes' ...sounds like ..A

Let sound of 'No'...sounds like.....B

Now pickup a stone and ask each one

Is this a stone?

Answers wil be A,B and A (orB)

As X... will say ..yes....A sound

     Y ...will say....No.....B sound

      Z ..will say....yes or no...A or B sound

Keep on asking the same question till any one changes sound from A to B ,or B to A

 One who changes is  a third person ...Z ..

Random ,because A and B will not change answer and hence sound of answer

Now we have person X and Y

Ask X....whether Y speaks truth?

            Answer will be......No..B sound

Ask Y ....whether X speaks truth

             Answer will be agsin ..No...B sound

As we know here both will say No...B sound....we can now understand ..

What is ..No..B sound ..how is the sound of No

Finaly Ask X and Y previous  question

Is this a stone?

One who sounds like B...No..is a lier .

Hence person Y

Remaing is person X...truth speaking
