Question

If India’s population is increasing at the rate of 13.6 million per year, then what percentage of increase in the world’s population in one calendar year is contributed by the Indians?
[Given: Current world population is 730 million, and it increases by 10 percent every year]
A. 1.5 percent
B. 17 percent
C. 1.7 percent
D. 15 percent

Answer 1

Hint: The world population is increasing day by day on a huge scale. According to the 2000 census, the world population was around 2 billion in 1900 and increased to 6 billion in 2000. Similarly, according to the census of 2011, the world population increased to 7.2 billion. India’s population was 1.2 billion in 2011 whereas it was 1 billion in 2000.

Complete answer:
In terms of biology, the word population defines the number of organisms belonging to the same species or group and living in a common geographical area, and breeding among themselves.
As per the data given in the question, the total population of the world is 730 million. Since every year there is an increase of 10 percent in the population so after one year the world population would go up to 803 million.

Let us assume India’s population as “x million”.
Now the population of India is \[13.6\] million in one year.
Therefore, India’s population will be \[x \pm 13.6\] million
So, the contribution that India gives to the world in terms of population is-
\[13.6 \times 100 \approx 1360 \div 803 \simeq 1.7 \]

So, here the answer is 1.7 percent, option C.

Note: Population growth is the increase in the number of individuals in a population. The global population was 1 billion in 1800 and it increased to 7.8 billion in 2020. The population growth rate is the rate at which the number of individuals increases in a particular population in a given time period. The increasing population has various negative effects on the economy and resource growth of the world and nation.
