If on 15 August 1947 was Friday, then what will be the day on 26 November 1949 ?

Saturday

\(\frac{Date + Month code + Century code + Century upper year + Quotient of Upper year/4}{7}\)

\(\frac{15+2+0+47+11}{7}\)

\(\frac{75}{7}\) =  Remainder 5 means Friday and here also Friday is given i.e. no change.

We have to find out 26/11/1949

\(\frac{Date + Month code + Century code + Century upper year + Quotient of Upper year/4}{7}\)

\(\frac{26+3+0+49+12}{7}\)

\(\frac{90}{7}\) =  Remainder 6 means Saturday

Therefore, Saturday is the correct answer.
