Solution
To solve this problem, we need to calculate the total number of visitors in a month and then divide it by the number of days in a month.
-
First, we need to find out how many Sundays are there in a month that starts with a Saturday. Since the month starts with a Saturday, the next day, Sunday, is the first day of the month. Therefore, there are 5 Sundays in this month.
-
The library has an average of 510 visitors on Sundays. So, the total number of visitors on Sundays is 510 * 5 = 2550.
-
There are 30 - 5 = 25 other days in the month.
-
The library has an average of 240 visitors on other days. So, the total number of visitors on other days is 240 * 25 = 6000.
-
The total number of visitors in the month is 2550 + 6000 = 8550.
-
The average number of visitors per day in the month is 8550 / 30 = 285.
So, the average number of visitors per day in a month of 30 days beginning with Saturday is 285.
