Population of Rajasthan = 570 lakhs and population of UP = 1660 lakhs. Area of Rajasthan = 3 lakh km² and area of UP = 2 lakh km².

(i) How many people are there per km² in both these States?

(ii) Which State is less populated?

Population of Rajasthan = 570 lakhs

Population of U.P = 1660 lakhs

And, area of U.P = 2 lakh km²

Now,

Population of Rajasthan in 3 km² area = 570 lakh

Population of Rajasthan in 1 km² area = = 190 lakh

Also,

Population of U.P in 2 km² area = 1660 lakh

Population of U.P in 1 km² area = = 830 lakh

(ii) From the above results, it can be observed that,

Population of Rajasthan in 1 km² area = 190 lakh
