Question

The population of the earth is doubling every 40 years. If the population of the earth is now 6 billion people how many people will be here when you are 95 years old?

Answer 1

Population after 95 years is more than 24 billion.

Step-by-step explanation:

The present size of the population is 6 billion.

Assuming that the population starts growing from the age of "0"

The number of people after 40 years is equal to two times the present population i.e 12 billion

The number of people after 80 years is equal to two times the population after 40 years i.e 24 billion

Thus population after 95 years is more than 24 billion.
