Question

India’s population has been steadily increasing from \[439\] millions in \[1961\] to \[1028\] millions in \[2001\]. Find the total increase in population from \[1961\] to \[2001\]. Write the increase in population in Indian System of Numeration, using commas suitably.

Answer 1

Hint: In this question, we have the population in specific years. We need to first calculate the number of people increasing in the given duration. Then we will make it in the Indian System of Numeration, using commas suitably. Then we can easily find out the required solution.

Complete step-by-step answer:
It is given that the question stated as, India’s population has been steadily increasing from \[439\] millions in \[1961\] to \[1028\] millions in \[2001\].
We need to find out the total increase in population from \[1961\] to \[2001\].
The Population of India in \[1961\] is \[439\] millions.
Also we have, the population of India in \[2001\] is \[1028\] millions.
Increase in population from \[1961\] to \[2001\] is
\[ \Rightarrow 1028 - 439\] millions
Let us subtracting the terms and we get,
\[ \Rightarrow 589\] millions
Now we will convert it from the Western numbering system to Indian numbering system,
[We know, one million = \[10,00,000\] ]
\[ = 58,90,00,000\]

Hence, the increase in population in Indian System of Numeration is \[ = 58,90,00,000\]

Note: The Indian numbering system is used in the Indian subcontinent to express large numbers. The terms lakh \[\left( {1,00,000} \right)\] and Crore \[\left( {1,00,00,000} \right)\] are the most commonly used terms to express large numbers in the system.
In the Western system, the next powers of ten are called one hundred thousand, one million, ten million, one hundred million, one billion, and so on.
One million=\[10,00,000\]=one lakh
One billion=\[1,00,00,00,000\] =Hundred crores.
