3.
A circulating library has an average of
480 visitors on Sundays and 240 on other
days. The average number of visitors per
day, in a month of 30 days beginning with
a Saturday, is
(1
280
(2) 272
(3)
270
(4)
266​

Answer 1

(1) ( 25 x 240 + 5 x 480 ) / 30 = ( 6000 + 2400 ) / 30 = 8400 / 30 = 280

Answer 2

Answer:

The average number of visitors for the month is 280.

Step-by-step explanation:

For a month having 30 days and starting with Saturday, there are 5 Sundays.

Number of visitors on each Sunday= 480

Total visitors on all the Sundays= 480×5 = 2400

Total visitors on all the other days of the month = 240× 25= 6000

Therefore, the average number of visitors in the entire month= Total visitors/Number of days

so, Average= (6000+2400)/30 = 280
