If 30 July 2015 was Thursday, then what was the day of the week on 03 September 2016?

Saturday

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 July 2015;

30 + 0 + 06 + 15 + 03 = 54

remainder of \(\frac{54}{7}\) = 05

Therefore, the code of 05 is Thursday

Similarly,

03 Sep 2016;

03 + 06 + 06 + 16 + 04 = 35

remainder of \(\frac{35}{7}\) = 0

Therefore, the code of 0 is Saturday
