If Tomorrow is Tuesday, what will be the day after 66 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 ".

66 / 7 = 9 ( Remainder = 3)

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

Hence after 63 days monday will occur again.

So we calculate after the remainder (3) , the answer is Thursday.

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