Given that December 3, 2000 was Sunday.
To find the day on January 3, 2001, we need to count the number of days between these two dates.
From December 3, 2000 to December 31, 2000:
Number of days =31−3=28 days
From January 1, 2001 to January 3, 2001:
Number of days =3 days
Total number of days =28+3=31 days
To find the day of the week, we divide the total days by 7:
31=7×4+3
This means 31 days =4 weeks +3 days
Starting from Sunday (December 3, 2000):
Adding 4 complete weeks brings us back to Sunday.
Adding 3 more days:
- Sunday +1 day = Monday
- Sunday +2 days = Tuesday
- Sunday +3 days = Wednesday
Therefore, January 3, 2001 was Wednesday.
The answer is Option 3: Wednesday.
