A group of people were having lunch together.........
Between 2,200 and 2,600 guests were invited to have lunch with the president.
The organizer decided to arrange the seating so that each table would accommodate an equal number of guests, and the number of guests at each table would be an odd number.
The organizer determined that the following arrangements would not work :
3 guests per table
(2 people would be left without seating)
5 guests per table
(4 people would be left out)
7 guests per table
(6 people would be left out)
9 guests per table
(8 people would be left out)
When he tried seating 11 guests per table,
EVERYONE had a place to sit.
How many people were invited to dine with the president?
