Explanation
A logic question designed to be difficult in the way it is worded.

What we know:
  • 5 foors are at least 11 sefens. So that is 55 sefens total for 5 of the foors
  • The remaining 2 foors have to be at least 5 sefens tall, so assume they are. That's 10 sefens for the other two
  • Add them all up and you have 65 sefens total for all 7 foors
  • That's an average of 9.3 sefens
So, yes it is possible for the average height of the group to be less than 10 sefens.
