If 11 July 2020 was Monday, what will be 14 October 2028?

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 }

11 July 2020;

11 + 0 + 06 + 20 + 05 = 42

remainder of \(\frac{42}{7}\) = 0

Therefore, the code of 0 is Saturday + 2 = ( Monday )

 

Similarly,

14 Oct 2028;

14 + 01 + 06 + 28 + 07 = 56

remainder of \(\frac{56}{7}\) = 0

Therefore, the code of 0 is Saturday + 2 = ( Monday )
