If 12 January 2019 was on Monday, what was the day on 14 December 1917?
Answer & explanation
Correct answer: option 4
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 }
12 Jan 2019;
12 + 01 + 06 + 19 + 04 = 42
remainder of \(\frac{42}{7}\) = 0
Therefore, the code of 0 is Saturday + 02 = ( Monday)
Similarly,
14 Dec 1917;
14 + 06 + 0 + 17 + 04 = 41
remainder of \(\frac{41}{7}\) = 06
Therefore, the code of 06 is Friday + 02 = ( Sunday )
