Question

double in about
Oa) 7 years
Ob) 10 years
Oc) 70 years
Od) 100 years

Answer 1

With a population growth rate of 1 percent, a country's population will

double in about option C. 70 years.

How did we get the value?

The rule of 70 is a quick way to estimate the doubling time of a population based on its growth rate. The rule of 70 states that you can approximate the doubling time by dividing 70 by the growth rate. In this case, with a population growth rate of 1 percent:

Doubling time ≈ 70 / Growth rate

Doubling time ≈ 70 / 1

Doubling time ≈ 70 years

Therefore, the correct answer is option C. 70 years
