If Today Is Thursday, what will be the day after 70 days

How do we solve it ?

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

70 / 7 = 10 ( Remainder = 0)

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

Hence after 70 days Thursday will occur again.

So we calculate after the remainder (0) , the answer is Thursday.

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