a library has an average of 150 visitors on sundays and 120 on other days . the avearge number of visitors per day in a month of 30 days beginning with a sunday is ?
"since the month begin with sunday , so there will be five sundays in the month required average = ( 150 * 5 + 120 * 25 ) / 30 = 3750 / 30 = 125 answer is d"
divide(add(multiply(add(floor(divide(30, add(const_3, const_4))), const_1), 150), multiply(subtract(30, add(floor(divide(30, add(const_3, const_4))), const_1)), 120)), 30)
