Average = sum of quantities/Total number of quantities
Now, for a month of 30 days starting with a Sunday, we would be having 5 Sundays and 25 other days.
Given, library has an average of 480 visitors on Sundays and 210 on other days.
Average number of visitors per day in a month $(= \frac{{480 \times 5 + 210 \times 25}}{{30}} = 255)$
