Givens

• There are 20 tables.
• 65% of the tables have 6 chairs at each table.
• 35% of the tables have 4 chairs at each table.

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?

$65\%\frac{20}{100\%} =13$

There are 13 tables of 6 chairs at each table.

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

$35\%\frac{20}{100\%} =7$

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

$13 tables \times 6 chairs=78 chairs$

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

$7 tables \times 4chairs=28chairs$

Therefore, the total number of chairs is

$78+28=106$

There are 106 chairs in the hospital cafeteria.
