If 15^th October 2008 was a Wednesday, then what was the day of the week on 14th October 2012?

Sunday

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 }

15 Oct 2008;

15 + 01 + 06 + 08 + 02 = 32

remainder of \(\frac{32}{7}\) = 04

Therefore, the code of 04 is Wednesday 

Similarly,

14 Oct 2012;

14 + 01 + 06 + 12 + 03 = 36

remainder of \(\frac{36}{7}\) = 01

Therefore, the code of 01 is Sunday
