There are 32 tables in a hall. Half the tables have 2 chairs each, 5 have 3 chairs each and the rest have 4 chairs each. How many chairs in total are in the hall?
Half of 32 tables is 32*(1/2) = <<32*(1/2)=16>>16 tables
16 tables have 2 chairs each for a total of 16*2 = <<16*2=32>>32 chairs
5 tables have 3 chairs each for a total of 5*3 = <<5*3=15>>15 chairs
There are 32-(16+5) = <<32-(16+5)=11>>11 tables left
11 tables have 4 chairs each for a total of 11*4 = <<11*4=44>>44 chairs
The total number of chairs is 32+15+44 = <<32+15+44=91>>91 chairs
