If 17th March falls on 4th day after tomorrow which is Thursday, then what day of week will fall on the last date of the month?

Monday

The correct answer is Option (4) → Monday

To find the day of the week for the last date of March, let's break down the information given:

1. Identify "Tomorrow": The phrase "tomorrow which is Thursday" tells us that tomorrow is Thursday. This implies that today is Wednesday.
2. Calculate the 17th of March: We are told the 17th of March falls on the 4th day after tomorrow.
• Tomorrow = Thursday
• 1st day after tomorrow = Friday
• 2nd day after tomorrow = Saturday
• 3rd day after tomorrow = Sunday
• 4th day after tomorrow = Monday
• Therefore, March 17th is a Monday.
3. Identify the last date of the month: March has 31 days. We need to find the day of the week for March 31st.
4. Calculate the day for March 31st:
• Number of days from March 17th to March 31st = $31 - 17 = 14$ days.
• Since 14 is exactly two weeks ($14 \div 7 = 2$ weeks), the day of the week remains the same.
• Alternatively: 17th (Mon), 24th (Mon), 31st (Mon).

Final Answer:

The last date of the month (March 31st) will be a Monday.
