If 100 cats killed 100 mice in 100 days, you can say that each cat killed one mouse the day after the last cat. So, if four cats killed four mice, and we're going of off the same basis that each cat killed one mouse the day after the last cat, then the answer would be 4.
The population after 15 years become according to the doubling time is 470000000.
According to the statement
We have given that the nation of 200 million people is growing at a rate of 9% per year.And we have to find that the What will its population be in 15 years.
So, For this purpose, we know that the
The doubling time is the time it takes for a population to double in size/value. It is applied to population growth etc.
So,
Population of nation is 200 million and growing at a rate of 9% per year.
So, 9% of the population is
Percentage population = 9/100*200,000,000
Percentage population = 9* 200,000,0
Percentage population = 1800,000,0.
It means 18000000 number of population is increased per year.
So, The total population increased in 15 years is 15*18000000
The total population increased in 15 years is 270000000.
The population after 15 years is 270000000 + 200,000,000
The population after 15 years is 470000000.
So, The population after 15 years become according to the doubling time is 470000000.
