If 15 August 1947 was Friday, then what was the day of the week on 26 January 1950?

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 }

15 Aug 1947;

15 + 03 + 0 + 47 + 11 = 76

remainder of \(\frac{76}{7}\) = 0

Therefore, the code of 0 is Saturday

Similarly,

26 Jan 1950;

26 + 01 + 0 + 50 + 12 = 89

remainder of \(\frac{89}{7}\) = 05

Therefore, the code of 05 is Thursday
