If 19 September 1999 was Sunday, then what was the day of the week on 19 January 2001?
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 }
19 Sep 1999;
19 + 06 + 0 + 99 + 24 = 148
remainder of \(\frac{148}{7}\) = 01
Therefore, the code of 01 is Sunday
Similarly,
19 Jan 2001;
19 + 01 + 06 + 01 + 0 = 27
remainder of \(\frac{27}{7}\) = 06
Therefore, the code of 06 is Friday
