Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Monday.
To find the day of the week on 7 March 2005 given that 31 December 2003 was a Wednesday:
From 31 December 2003 to 31 December 2004:
2004 is a leap year: 366 days
Days in a week: 366 ÷ 7 = 2 extra days
31 December 2004: Friday
From 31 December 2004 to 7 March 2005:
January: 31 days
February: 28 days
March: 7 days
Total: 31 + 28 + 7 = 66 days
66 ÷ 7 = 3 extra days
Adding 3 days to Friday: Monday
Therefore, 7 March 2005 was a Monday.
