The question is, what's the total number of chairs in the cafeteria?

We know by given that 100% represents 20 tables. We can use the rule of three, to find the number that represents a 65%, that is, if 100% is 20 tables, 65% how many tables would be?

There are 13 tables of 6 chairs at each table.

Similarly, if 100% represents 20 tables, 35% how many tables would represent?

There are 7 tables of 4 chairs at each table.

Then, we need to multiply to find the total number of chairs.

We know that there are 13 tables of 6 chairs, so

We also know that there are 7 tables of 4 chairs, so

Therefore, the total number of chairs is

There are 106 chairs in the hospital cafeteria.
