If Today Is Saturday, what was the day before 88 days

How do we solve it ?

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

88 / 7 = 12 ( Remainder = 4)

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

Hence before 84 days Saturday would occur again.

So we calculate before the remainder (4) , the answer is Tuesday.

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