Arental hall has 60 tables. 55% of the tables have 10 chairs at each table. the remaining 45% of the tables have 8 chairs at each table.

Your question isn't really a question... What are you supposed to find or work out? This is what I can gather based on the question:

55% of 60 = 33

33 tables have 10 chairs each.

45 % of 60 = 27

27 tables have 8 chairs each.

If the question is asking how many chairs are there in the hall:

33 x 10 = 330

27 x 8 = 216

330 + 216 = 546 chairs in total
