If Today Is Wednesday, what will be the day after 39 days

How do we solve it ?

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

39 / 7 = 5 ( Remainder = 4)

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

Hence after 35 days Wednesday will occur again.

So we calculate after the remainder (4) , the answer is Sunday.

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