If Today Is Sunday, what will be the day after 43 days

How do we solve it ?

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

43 / 7 = 6 ( Remainder = 1)

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

Hence after 42 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.
