Today is Monday. After 61 days, it will be

### Concept & Cyclical Nature of the Week The days of the week repeat in a continuous 7-day cycle. To find the day of the week after a given number of days, divide the number of days by 7 and add the remainder (odd days) to the current day. ### Step-by-Step Solution - We are given that today is Monday. - We need to find the day after 61 days. - Divide 61 by 7 to find the number of full weeks and the remainder. - $61 \div 7 = 8$ weeks with a remainder of 5 days. - The 5 days represent the odd days. - Add these 5 odd days to the current day (Monday). - Monday + 5 days = Saturday. ### Exam Strategy & Shortcut Whenever a question asks "after $X$ days," simply calculate $X \pmod 7$ and count forward from the given day. $61 \pmod 7 = 5$. Monday + 5 = Saturday. (Alternatively, Monday - 2 = Saturday, since $+5$ is the same as $-2$). ### Common Pitfall Adding the full 61 days manually or forgetting that "after 61 days" just means advancing by the remainder of the division. ### Final Answer Therefore, the correct answer is **Saturday**.
