Solution
Find the least number of days.
We can determine the least number of days by using the concept of time and work.
- From the given, day after the day before yesterday is yesterday.
- Now, before five days, yesterday was Thursday. So before five days, it was Friday, which means that, Today is Wednesday.
- Now, Yesterday is three days before the day after tomorrow.
- It is on Monday that we can say 'Yesterday was Sunday".
- So, from today that is Wednesday, Monday is two days ago.
Therefore, two days ago from today Sunday was three days before the day after tomorrow.
