A Mind Boggling IQ Question

Q. Four prisoners escape from a prison. 
The prisoners, Mr. East, Mr. West, Mr. South, Mr. North head towards different directions after escaping.  The following information of their escape was supplied: 

• The escape routes were North Road, South Road, East Road and West Road
• None of the prisoners took the road which was their namesake
• Mr. East did not take the South Road
• Mr.West did not the South Road
• The West Road was not taken by Mr. East

What road did each of the prisoners take to make their escape ?


Answer :

Put all the given information into the table structure as follow:
 
                  North Road     South Road      East Road      West Road
Mr. North        No                    
Mr. South                               No 
Mr. East                                 No                     No                   No
Mr. West                                No                                             No 

Now from table, two things are obvious and they are: 

• Mr.North took the South Road
• Mr.East took the North Road

Put this information into the table, Also keep in mind that the prisoners head towards different directions after escaping. 

                  North Road     South Road      East Road      West Road
Mr. North        No                    YES                   No                   No
Mr. South        No                     No 
Mr. East         YES                    No                     No                   No
Mr. West          No                     No                                             No 

Now from the table: 

• Mr.West took the East Road

So the answer is: 

• Mr.North took the South Road
• Mr.South took the West Road
• Mr.East took the North Road
• Mr.West took the East Road
