Calculation of the First Monday after the Given Tuesday

To determine the date of the first Monday after the given Tuesday, we need to find the number of days between the two dates and then add that number of days to the given Tuesday.

Let's break down the steps:

1. Find the number of days between the given Tuesday and the first Monday after it. 2. Add that number of days to the date of the given Tuesday to find the date of the first Monday.

Step 1: Finding the Number of Days

To find the number of days between two dates, we can subtract the date of the first Tuesday from the date of the first Monday after it.

In this case, the given Tuesday is the 30th of January. To find the first Monday after it, we need to determine the number of days between the 30th of January and the 1st of February.

The number of days between the 30th of January and the 1st of February is 2 days.

Step 2: Calculating the Date of the First Monday

Now that we know there are 2 days between the given Tuesday and the first Monday after it, we can add those 2 days to the date of the given Tuesday to find the date of the first Monday.

Adding 2 days to the 30th of January gives us the 1st of February.

Therefore, the first Monday after the given Tuesday (30th of January) is the 1st of February.

So, the correct answer is 2) 7.
