If Tomorrow is Saturday, what will be the day after 1 days

How do we solve it ?

If tomorrow is saturday, today is friday.

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

1 / 7 = -0 ( Remainder = 1)

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

Hence after 0 days friday will occur again.

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

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