Difficulty: Easy
Correct Answer: Same day of the week as today
Explanation:
Introduction / Context:
This question is designed to reinforce the idea that days of the week repeat in a fixed 7-day cycle. When you move forward by a number of days that is a multiple of 7, you always land on the same day of the week. Here, the phrase “two weeks” is simply another way of saying 14 days, which is exactly two full cycles of the weekday pattern.
Given Data / Assumptions:
Concept / Approach:
We use modular arithmetic with respect to 7. Every block of 7 days brings us back to the same weekday. Thus, adding 14 days is equivalent to adding 0 days modulo 7, because 14 is a multiple of 7. Therefore, the weekday after 14 days is identical to the starting weekday.
Step-by-Step Solution:
Step 1: Recognise that 1 week has 7 days and 2 weeks have 14 days.Step 2: Compute 14 / 7. We get 14 = 7 * 2, so 14 days correspond to exactly 2 full weeks.Step 3: Moving forward by one full week (7 days) from any day of the week brings you to the same day next week.Step 4: Moving forward another full week (another 7 days) again lands you on the same weekday.Step 5: Therefore, moving forward 14 days in total keeps you on the same day of the week as today, which is Wednesday in this question.
Verification / Alternative check:
You can list a short example: if today is Wednesday, then after 7 days it is again Wednesday, and after another 7 days it is once more Wednesday. This simple listing confirms the mathematical reasoning that adding any multiple of 7 days leaves the weekday unchanged.
Why Other Options Are Wrong:
The “previous day” or “next day” options would require moving 6 or 1 days modulo 7, not 14. “Two days after” would need a remainder of 2 when dividing by 7. “Cannot be determined” is incorrect because the weekday is fully determined by the number of days added modulo 7.
Common Pitfalls:
Final Answer:
Exactly two weeks from today it will be the same day of the week as today.
