Solution
Given, population of India in 1961 = 439 million
= 439 × 1000000 = 439000000 [v 1 million = 1000000] and population of India in 2001 = 1028 million
= 1028 × 1000000
= 1028000000 [v 1 million = 1000000] / Total increase in population from 1961 to 2001
= Population in 2001 – Population in 1961
= 1028000000 – 439000000
= 589000000 = 589 × 1000000
= 589 million
So, the increase population in Indian System of Numeration = 58,90,00,000
