Answer:
44 seats.
Explanation:
Ends of 5 tables are placed together. When this is done, there are only 2 ends, one on each side of the 5 tables as shown in the image below. All the other ends are blocked when tables are joined together.
Since, 2 people can sit on each end, 4 people can sit on two ends of the tables.
For one table there are 2 sides and on each side 4 people can be seated. No sides are blocked, so all the sides of 5 tables are open.
Total number of sides of 5 tables = 10
Number of people on each side = 4
So, total number of people on 10 sides would be = 40
Hence, total seats that would be available = Seats on ends + Seats on sides = 4 +40 = 44
44 seats are available if the end of 5 tables are placed together.
