math Olympiad problem for grade & middle school

We just did our first problem from Math Olympiad Contest Problems for Elementary and Middle Schools by George Lenchner

problem

Suppose today is Tuesday. What day of the week will it be 100 days from now?
4 min.

answer

Every 7 days from 'today' will be Tuesday. Since 98 is a multiple of 7, the 98th day from today will be Tuesday. Then the 100th day will be Thursday.
