a library has an average of 500 visitors on sundays and 140 on other days . the average number of visitors per day in a month of 30 days beginning with a sunday is :
"explanation : since the month begins with a sunday , so there will be five sundays in the month , required average = ( 500 * 5 + 140 * 25 ) / 30 = 6000 / 30 = 200 answer : b ) 200"
divide(add(multiply(add(floor(divide(30, add(const_3, const_4))), const_1), 500), multiply(subtract(30, add(floor(divide(30, add(const_3, const_4))), const_1)), 140)), 30)
