If 20 July 2021 was Tuesday, then what was the day of the week on 28 November 2021?
Answer & explanation
Correct answer: option 1
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 July 2021;
20 + 0 + 06 + 21 + 05 = 52
remainder of \(\frac{52}{7}\) = 03
Therefore, the code of 03 is Tuesday
Similarly,
28 Nov 2021;
28 + 04 + 06 + 21 + 05 = 64
remainder of \(\frac{64}{7}\) = 01
Therefore, the code of 01 is Sunday
