If Today Is Tuesday, what was the day before 97 days

How do we solve it ?

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

97 / 7 = 13 ( Remainder = 6)

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

Hence before 91 days Tuesday would occur again.

So we calculate before the remainder (6) , the answer is Wednesday.

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