Give the step-by-step reasoning process and then the final answer. 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) = 16 tables. 16 tables have 2 chairs each for a total of 16 * 2 = 32 chairs. 5 tables have 3 chairs each for a total of 5 * 3 = 15 chairs. There are 32 - (16 + 5) = 11 tables left. 11 tables have 4 chairs each for a total of 11 * 4 = 44 chairs. The total number of chairs is 32 + 15 + 44 = 91 chairs.
The final answer: 91.
