Answer 1

To determine the output of calling n2.calculate(), we need to analyze the code provided.

The class Addition has an __init__ method that initializes two instance variables, first and second, with the values provided as arguments. The calculate method calculates the sum of first and second, stores it in self.answer, and then prints it.

Here's a breakdown:

1. When n2 is created with n2 = Addition(3000, 1000), the instance variables are set as follows:

   • self.first = 3000
   • self.second = 1000

2. When n2.calculate() is called, the method calculates:

   • self.answer = self.first + self.second = 3000 + 1000 = 4000

3. The print statement in the calculate method then outputs:

   Addition of two numbers = 4000
   

So the output of calling n2.calculate() is:

Addition of two numbers = 4000

Therefore, the correct response is: Addition of two numbers = 4000.
