Answer 1

Hint: The above question tells us to find out the population in the year 2001.The main approach towards solving such kind of question is by adding the population increase till the year 2001 to the given amount of population in the year 1991 so that we can find out the population in the year 2001.

Complete step-by-step solution:
The above given question is based on a simple mathematical operation which is just addition. It can be solved in the following way where the population of a place named Sundarnagar is given as 2,35,471.
This population was the record in the year 1991.So after 10 years that is in the year 2001, we have been given an increased population amount which is 72,958. So, the main approach is to find the population in the year 2001.

This can be achieved when the population in the year 1991 is added with the given increased population till the year 2001.So we can write it as, \[235471 + 72958 = 308429\]

Therefore, population in this city for the year 2001 is 3,08,429.


Note: An important thing to note is that the two given numbers are very large.So addition of such large number is done in such a way that the numbers are arranged in columns tens under tens,hundreds and hundreds ,etc and we continue the process until digits are added in the column.
