If 31 August 2008 was Sunday, then what was the day of the week on 30 August 2012?

Thursday

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}

31 Aug 2008;

31 + 03 + 06 + 08 + 02 = 50

remainder of \(\frac{50}{7}\) = 01

Therefore, the code of 01 is Sunday

Similarly,

30 Aug 2012;

30 + 03 + 06 + 12 + 03 = 54

remainder of \(\frac{54}{7}\) = 05

Therefore, the code of 05 is Thursday
