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

(ii) Which State is less populated?

Dear Student

(i) From the question, it is given that,
Population of Rajasthan = 570 lakh
Area of Rajasthan = 3 lakh Km^2
Then, population of Rajasthan in 1 km^2area = (570 lakh)/ (3 lakh km^2)
= 190 people per km
Population of UP = 1660 Lakh
Area of UP = 2 Lakh km^2
Then, population of UP in 1 lakh km^2area = (1660 lakh)/ (2 lakh km^2)
= 830 people per km

(ii) By comparing the two states Rajasthan is the less populated state.

Thanks
