A task is assigned to a group of 11 men, not all of whom have the same capacity to work. Every day exactly 2 men out of the group work on the task, with no pair of men working together twice. Even after all the possible pairs have worked once, all the men together had to work for exactly one day more to finish the task. What is the number of days that will be required for all the men working together to finish the job.

Within a same zone=3 (villages) * 3 (direct lines) *4 (zones)=36
Different zones=6 pairs*3 (villages of 1 zone) *3 (villages of other zone)=54
