In 2014, the populations of china and india were approximately 1.355 and 1.255 billion people,45 respectively. however, due to central control the annual population growth rate of china was 0.44% while the population of india was growing by 1.25% each year. if these growth rates remain constant, when will the population of india exceed that of china?

in the year 2023

Step-by-step explanation:

Initial population of China = 1.355  billion

Initial population of India = 1.255  billion

Annual population growth rate of China = 0.44% = 0.0044

Annual population growth rate of India = 1.25% = 0.0125

Now,

Final population = P₀

Here,

P₀ = initial population

t = time

Thus,

Population of India > Population of China

1.255  > 1.355  

or

> 1.07968

taking natural log both sides

0.0081t > ln (1.07968 )

or

0.0081t > 0.0766

or

t > 9.465

Hence,

9.465 year after 2014

i.e

in 2014 + 9.465 = 2023.46

in the year 2023

shorter piece is 2: 3, so just reverse it, and you get 3: 2
