To find how many tables have 4 chairs, we can follow these steps:

1. Total number of tables: 60
2. Percentage of tables with 4 chairs: 65%

Now, calculate the number of tables with 4 chairs: $\text{Tables with 4 chairs} = 65\% \text{ of } 60 = \frac{65}{100} \times 60 = 0.65 \times 60 = 39$

So, 39 tables have 4 chairs.
