Solution
The correct option is C Sunday
Clearly, every day repeats itself on the seventh day. Now, 17th Dec. 2002 - 16th Dec.
2003 is a period of 365 days. Dividing by 7, we get 52 weeks and one day. Thus, the 365th day will be the same as the first day, i.e., 16th Dec. 2003 is also Saturday.
Now, 16th Dec. 2003 - 15th Dec. 2004 is a period of 366 days (because 2004, being a leap year, has 29 days in February). Thus, as shown above, 14th Dec. 2004 will be the same as 16th Dec. 2003, i.e., Saturday. So, 21st Dec. 2004 is also Saturday and thus, 22nd Dec. 2004 is a Sunday.
