If a boy has music lessons on every third day soccer every sixth day and karate every ninth day on which day will he have all three?

Answer 1

on the 18th day. that answer is incorrect. Working on a 7 day schedule, and not a 5, the days that it intersects is complicated.wokring on a normal calender, depending on the month that the schedule recurrs, and begins, calculating holidays (ie chrismas) and if the child participates in indoor soccer, or regular outdoor soccer limiting the time available due to weather conditions, the possibilities are endless and impossible to configure. that algorithms nessisary for this are limitless. That would make the answer impossible. Now if the question was: Starting on monday, January 1, 2007, if a boy has music lessons on every third day, indoor soccer every sixth day, and karate lessons every ninth day, on which day would all three intersect? Then the answer would be: January 1, 2007.
