If 20 February 2013 was Wednesday, then what was the day of the week on 28 February 2016?
Answer & explanation
Correct answer: option 2
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 }
20 Feb 2013;
20 + 04 + 06 + 13 + 03 = 46
remainder of \(\frac{46}{7}\) = 04
Therefore, the code of 04 is Wednesday
Similarly,
28 Feb 2016;
28 + 03 + 06 + 16 + 04 = 57
remainder of \(\frac{57}{7}\) = 01
Therefore, the code of 01 is Sunday
