If 28 February 2015 was Saturday, then what was the day of the week on 28 February 2021?
Answer & explanation
Correct answer: option 4
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 }
28 Feb 2015;
28 + 04 + 06 + 15 + 03 = 56
remainder of \(\frac{56}{7}\) = 0
Therefore, the code of 0 is Saturday
Similarly,
28 Feb 2021;
28 + 04 + 06 + 21 + 05 = 64
remainder of \(\frac{64}{7}\) = 01
Therefore, the code of 01 is Sunday
