  In the verses below he says-
about the cunning hotel owner who managed
accommodate ten guests in nine rooms
so that each of them got
separate room.  How did he do it?
If you guess it, write.                       
                                          
    There were ten eccentrics,              
  Those tired companions.               
  That they decided to knock on the door         
  Taverns "Glorious fellow".             
                                          
    - Let me spend the night, master,           
  You will not be at a loss,               
  We just need to sleep for the night,          
  We were soaked to the skin.                
  The owner was glad to see those guests,           
  Well, here’s the unfortunate problem:                
  He only has nine rooms            
  And only nine beds.              
                                          
    - I will offer eight guests           
  Bed with honor,              
  And two will have to sleep through the night        
  In the same bed together.              
                                          
    As soon as he said, and immediately there was a cry,        
  Faces are red with anger:                
  None of all ten              
  Doesn't want to make room.                
                                          
    How to cool the passions of those ardors       
 Moderate those worries?                
  But the old rogue was the master            
  And resolved the doubts.                 
                                          
    Bye to the first two travelers,           
  So as not to be judged harshly,               
  He asked to go to room "A"         
  And wait a little.                 
                                          
    The third slept in "B", the fourth in "C",  
  Our fifth one slept all night in "G",       
  We found accommodation for the night in “D”, “E”, “F”, “Z”    
  From sixth to ninth.                
                                          
    Then, returning again to “A”,       
  Where the two were waiting for him,                  
  HeI was glad to hand over the key to "I"       
  To the tenth hero.                      
                                          
    Although many years have passed since then,     
  It is unclear to anyone                       
  How was the owner able to place           
  One by one guests.                    
                                          
    Or arithmetic is old,                
  Or a miracle is before us,                 
  Understand what, how and why,           
  Try it yourself.
