If 2st January 2008 was a Wednesday, then what was the day of the week on 1st January 2012?
Answer & explanation
Correct answer: option 3

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 }
02 Jan 2008;
02 + 01 + 06 + 08 + 02 = 19
remainder of \(\frac{19}{7}\) = 05
Therefore, the code of 05 is Thursday - 01 = ( Wednesday )
Similarly,
01 Jan 2012
01 + 01 + 06 + 12 + 03 = 23
remainder of \(\frac{23}{7}\) = 02
Therefore, the code of 02 is Monday - 01 = ( Sunday )
