 Hello and welcome to the session, I am Deepika here. Let's discuss the question which says population of Rajasthan is equal to 570 lakhs and population of UP is equal to 1660 lakhs. Area of Rajasthan is equal to 3 lakh km2 and area of UP is equal to 2 lakh km2. Part 1, how many people are there per km2 in both these states? Part 2, which state is less populated? Now for this question we will take the help of unitary method in which we first find the value of one unit and then the value of the required number of units. So let's start the part 1, the square in both these states is equal to 570 lakhs is equal to 1 meter square. So for km2 area, there are which is equal to 190 people, 190 people per km2. Number of UP is equal to 1660, that is the number of people UP is equal to 1660 lakhs square area. There are 1660 lakhs for 1 meter square area, there are 1660 upon 2 which is equal to 830 people. Now this part is Rajasthan people per km2 and in UP people per km2. Now let's move to the part 2, it is less populated. Now there are 2 states Rajasthan and UP, there are 190 for UP, there are 8 km2. So Rajasthan is less populated because it is less Rajasthan. I hope the solution is clear to you.
