Question
A park has an average of 140 visitors on Sundays and 80
on other day. The average number of visitors in a month of 30 days starting with Sunday isSolution
As the month begin with Sunday, so there will be five Sundays in the month. So, Total visitors on Sundays = 140 x 5 = 700 & Total visitors on other days = 80 x 25 = 2000Â Total visitors in a month = 700 + 2000 = 2700 Now, average visitors in a month = 2700/30 = 90
