If 30 January 2010 was Saturday, then what was the day of the week on 01 March 2011?
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 }
30 Jan 2010;
30 + 01 + 06 + 10 + 02 = 49
remainder of \(\frac{49}{7}\) = 0
Therefore, the code of 0 is Saturday
Similarly,
01 March 2011;
01 + 04 + 06 + 11 + 02 = 24
remainder of \(\frac{24}{7}\) = 03
Therefore, the code of 03 is Tuesday
