The population of a country increases by 2.5 percent yearly if the population is 25 million in 1960 the population in the year 2000 would be?

Answer 1

If the population of a country increases by 2.5% yearly, then that is a multiplicative factor of 1.025. Between 1960 and 2000, there are 40 years, so raise that factor to the power to 40, 1.02540, and you get 2.685. If the starting population in 1960 were 25 million, then, with a population growth of 2.5% per year, the population in 2000 would be 2.5 million times 2.685, or 6.7 million.

Answer 2

To find the population in the year 2000, you can use the formula:

Population in 2000 = Population in 1960 * (1 + growth rate)^number of years

In this case, the growth rate is 2.5% or 0.025, and the number of years between 1960 and 2000 is 40. Plugging in the values, you get:

Population in 2000 = 25 million * (1 + 0.025)^40 ≈ 105.92 million
