Answer 3

Calculating the Number of People in the Third House

To calculate the number of people living in the third house, we can use the information provided about the number of people in the first and second houses.

Given: - In the first house, there are 400 people. - In the second house, there are 100 more people than in the first house. - In the third house, there are 3 times as many people as in the second house.

Let's calculate the number of people in the third house step by step.

Step 1: Calculate the Number of People in the Second House

The number of people in the second house is 400 (from the first house) + 100 (additional people) = 500 people.

Step 2: Calculate the Number of People in the Third House

The number of people in the third house is 3 times the number of people in the second house, which is 3 * 500 = 1500 people.

Therefore, there are 1500 people living in the third house.
