If Tomorrow is Tuesday, what will be the day after 27 days

How do we solve it ?

If tomorrow is tuesday, today is monday.

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

27 / 7 = 3 ( Remainder = 6)

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

Hence after 21 days monday will occur again.

So we calculate after the remainder (6) , the answer is Sunday.

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