If 29th September 2015 was a Tuesday, then what was the day of the week on 28th September 2019?
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 }
29 Sep 2015;
29 + 06 + 06 + 15 + 03 = 59
remainder of \(\frac{59}{7}\) = 03
Therefore, the code of 03 is Tuesday
Similarly,
28 Sep 2019;
28 + 06 + 06 + 19 + 04 = 63
remainder of \(\frac{63}{7}\) = 0
Therefore, the code of 0 is Saturday
