A book exhibition has an average of 520 visitors on Sundays and 250 on other days. What is the average number of visitors per day in a month of 30 days beginning with a Sunday?
295
In a month of 30 days beginning on a Sunday, there will be 4 complete weeks and another two days which will be Sunday and Monday
Hence there will be 5 Sundays and 25 other days in a month of 30 days beginning with a Sunday
Average visitors on Sundays = 520
Total visitors of 5 Sundays = 520×5
Average visitors on other days = 250
Total visitors of other 25 days = 250×25
Total visitors =(520×5)+ (250×25)
Total days=30
Avg. no. = 295
