If Tomorrow is Saturday, what will be the day after 17 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 ".

17 / 7 = 2 ( Remainder = 3)

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

Hence after 14 days friday will occur again.

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

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