If Tomorrow is Wednesday, what will be the day after 81 days

How do we solve it ?

If tomorrow is wednesday, today is tuesday.

A week has 7 days " Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday ".

81 / 7 = 11 ( Remainder = 4)

So you can say that after multiples of 7 days, the day will repeat itself as tuesday.

Hence after 77 days tuesday will occur again.

So we calculate after the remainder (4) , the answer is Saturday.

Simple Logic = And whatever the remainder obtained is, add that to the day.
