Question

Answer 1

Answer is Wednesday

Step by step explanation

First of all,we know that a week has 7 days

So 15 days ago it was Tuesday.

Now 15 days after Tuesday , 2 weeks completed and only 1 day is the odd day

So answer is Wednesday

Answer 2

Today is Wednesday.

Given : It was Tuesday 15 days ago.

To find : Which day of the week is today?

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the required day of the week)

We know that, a day of week repeats itself after (or, before) a one week or multiple number of complete weeks.

Now,

Tuesday + 15 days = Today

Tuesday + 14 days + 1 day = Today

Tuesday + 2 weeks + 1 day = Today [As, one week = 7 days]

Now, after 2 complete weeks the Tuesday is being repeated. (i.e. Tuesday + 2 weeks = Tuesday)

Which implies,

Tuesday + 1 day = Today

Which further means, today is 1 day after Tuesday. And, Wednesday comes after 1 day of Tuesday.

So,

Tuesday + 1 day = Today = Wednesday

Hence, today is Wednesday.
