If the third day of a month falls on Friday, what day will be on the fourth day after twenty first of the month?
This calendar puzzle can be solved by first identifying the target date and then calculating the "odd days" (the remainder after dividing by 7) to find the day of the week.
- The question asks for the day on "the fourth day after twenty first of the month".
- This means we need to find the day for the date: 21 + 4 = 25th of the month.
- We are given that the 3rd of the month is a Friday.
- First, we find the total number of days between our known date (the 3rd) and our target date (the 25th):
25 - 3 = 22 days.
- Next, we find the "odd days" by finding the remainder when the total number of days is divided by 7 (since the days of the week repeat in a 7-day cycle):
22 ÷ 7 = 3 with a remainder of 1.
- So, there is 1 odd day between the two dates.
- The day of the week for the 25th will be 1 day after the day of the 3rd.
- Friday + 1 day = Saturday.
Final Answer: The day will be on a Saturday.
