If Today Is Friday, what was the day before 46 days

How do we solve it ?

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

46 / 7 = 6 ( Remainder = 4)

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

Hence before 42 days Friday would occur again.

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

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