To estimate the number of cars sold in India each year, we can take the following steps:

1. Estimate the population of India

As of 2021, the population of India is approximately 1.4 billion.

2. Estimate the percentage of the population that owns a car

According to the World Bank, the number of passenger cars per 1,000 people in India is around 20. This means that for every 1,000 people, there are 20 cars.

3. Calculate the car ownership rate

Using the data from step 2, we can determine the car ownership rate by dividing the number of cars by the population.
Car Ownership Rate = Number of Cars / Population
Car Ownership Rate = 20 / 1,000
Car Ownership Rate = 0.02 (or 2%)

4. Estimate the average lifespan of a car

We'll assume that the average car in India has a lifespan of 10 years.

5. Calculate the number of cars that need to be replaced each year

Since the average car has a lifespan of 10 years, we can estimate that 10% of cars need to be replaced each year.

6. Estimate the number of new cars needed each year

To estimate the number of new cars needed each year, we'll multiply the car ownership rate by the population and then multiply by the percentage of cars that need to be replaced.
New Cars Needed = (Car Ownership Rate * Population) * (Percentage of Cars Replaced)
New Cars Needed = (0.02 * 1,400,000,000) * 0.1
New Cars Needed = 28,000,000 * 0.1
New Cars Needed = 2,800,000

7. Consider the growth rate of car sales

The car market in India is growing, so we should take this into account when estimating the number of cars sold each year. Let's assume a 5% growth rate in car sales.

8. Calculate the number of cars sold in India each year

To calculate the number of cars sold in India each year, we'll multiply the number of new cars needed by the growth rate.
Cars Sold Each Year = New Cars Needed * (1 + Growth Rate)
Cars Sold Each Year = 2,800,000 * 1.05
Cars Sold Each Year ≈ 2,940,000

So, approximately 2.94 million cars are sold in India each year. Keep in mind that this is a rough estimation and the actual number can vary depending on various factors such as economic conditions, government policies, and consumer preferences.
