If it was a Sunday on 30 January 2000, then what was the day of week on 1 March 2004?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Monday
From 30 January 2000 to 30 January 2004 there are 366 + 365 + 365 + 365 = 1461 days, and 1461 ÷ 7 leaves a remainder of 5. So 30 January 2004 was Sunday + 5 = Friday.
From there to 1 March 2004 is 1 + 29 + 1 = 31 days (2004 being a leap year), and 31 ÷ 7 leaves 3. Friday + 3 = Monday.
