If 13 September 2003 is a Saturday, then what will be the day of the week on 14 February 2005?
Answer & explanation
Correct answer: option 3
Using Code Method :-
\(\frac{Date+Month code+Year code+Last 2 digits of yr+Leap yrs till given yr}{7}\)
( Note: Remainder of the above sum will be the code of week day }
13 Sep 2003;
13 + 06 + 06 + 03 + 0 = 28
remainder of \(\frac{28}{7}\) = 0
Therefore, the code of 0 is Saturday
Similarly,
14 Feb 2005;
14 + 04 + 06 + 05 + 01 = 30
remainder of \(\frac{30}{7}\) = 02
Therefore, the code of 02 is Monday
