If today is Wednesday, what day will it be after 100 days?
- A. Thursday
- B. Friday
- C. Saturday
- D. Sunday
Explanation
Dividing 100 by 7 gives 14 weeks with a remainder of 2, so the day advances by two from Wednesday to Friday. Only the remainder matters, because whole weeks return to the same day. This remainder method solves every calendar question of this type.
