If Today Is Monday, what will be the day after 31 days

If today is monday,what day of the will it be 31 days from today ?
Thursday

How do we solve it ?

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

31 / 7 = 4 ( Remainder = 3)

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

Hence after 28 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.
