Question 04

A library has an average of 510 visitors on sundays and 240 on other days. The average number of visitors per day in a month of 30 days beginning with a sunday is

If the month is beginning with sunday then there will be 5 sundays in the month

Therefore, the required average = (5 x average visitors on sunday + 25 x average visitors on other day)/ no. Of days in a month

= (5 x 510 + 25 x 240)/ 30

= (2550 + 6000) / 30

= 8550 / 30

= 285

Therefore, the required average is 285.
