If Today Is Thursday, what will be the day after 15 days

If today is thursday,what day of the will it be 15 days from today ?
Friday

How do we solve it ?

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

15 / 7 = 2 ( Remainder = 1)

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

Hence after 14 days Thursday will occur again.

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

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