Question 157
India's population has been steadily increasing from 439 million in 1961 to 1028 million 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

Given, population of India in 1961 = 439 million
= 439 $\times$ 1000000 = 439000000 [$\because$ 1 million = 1000000]
and population of India in 2001 = 1028 million
= 1028 $\times$ 1000000 = 1028000000 [$\because$ 1 million = 1000000]
$\therefore$ Total increase in population from 1961 to 2001
= Population in 2001 - Population in 1961
= 1028000000 - 439000000 = 589000000
= 589 $\times$ 1000000 = 589 million
So, the increase in population according to the Indian System of Numeration = 58,90,00,000.
