Problem: a library has an average of 510 visitors on sundays and 240 on other day . the average number of visitors in a month of 10 days starting with sunday is
Rationale: "explanation : as the month begin with sunday , so there will be five sundays in the month . so result will be : = ( 510 × 5 + 240 × 25 / 10 ) = ( 8550 / 10 ) = 855 answer : option d"
annotated_formula: divide(add(multiply(add(floor(divide(10, add(const_3, const_4))), const_1), 510), multiply(subtract(10, add(floor(divide(10, add(const_3, const_4))), const_1)), 240)), 10)
