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

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

Dear Student

From the question, it is given that,
Population of Rajasthan = 570 lakh
Area of Rajasthan = 3 lakh Km²
Then, population of Rajasthan in 1 km² area = (570 lakh)/ (3 lakh km²)
= 190 people per km

Population of UP = 1660 Lakh
Area of UP = 2 Lakh km²
Then, population of UP in 1 lakh km² area = (1660 lakh)/ (2 lakh km²)
= 830 people per km

Thanks
