if today is Sunday, what day will it be in 100 days' time?

In 100 days it will be two days more than 14 weeks.

100/7 = 14 2/7

tuesday because it will be second day after the two weeks

To find out what day it will be in 100 days' time, you need to determine the day of the week that follows Sunday for each day until you reach the 100th day.

One common method to determine the day of the week is by using modular arithmetic. There are seven days in a week, so if you divide the number of days by seven, the remainder will give you the day of the week.

For example, let's start with Sunday as day 1. If you add one day, you get Monday (2). Adding another day results in Tuesday (3), and so on. Once you reach the seventh day (Saturday), if you add one more day, it circles back to Sunday (1). This pattern repeats every seven days.

So, to determine the day in 100 days' time, divide 100 by 7, which gives you a quotient of 14 and a remainder of 2. Since we start with Sunday, we then count two more days, which gives us Tuesday. Therefore, in 100 days' time, it will be Tuesday.
