A country has a population of 200 million and a total growth rate of 0.45 percent. What is the approximate simple increase in one year?

Answer and explanation

Correct answer: 900000

A simple one-year increase is calculated by applying the percentage growth rate to the starting population. The rate 0.45 percent must be written as a decimal, \(0.45/100 = 0.0045\). Multiplying this fraction by the population gives the number added during one year.

The increase is \(200000000 \times 0.0045 = 900000\). Therefore, approximately 900000 people, or 9 lakh people, are added in one year. Option C is correct. The percentage looks small, but it is applied to a very large base population, so the resulting number is substantial.
