## How do we solve it ?

If tomorrow is monday, today is sunday.

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

57 / 7 = 8 ( Remainder = 1)

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

Hence after 56 days sunday will occur again.

So we calculate after the remainder (1) , the answer is Monday.

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