# Q.3 Population of Rajasthan = 570 lakhs and population of UP = 1660 lakhs. Area of Rajasthan = 3 lakh $$km^2$$ and area of UP = 2 lakh $$km^2$$. (i) How many people are there per $$km^2$$ in both these States? (ii) Which State is less populated?

Answer :

Population of Rajasthan = 570 lakhs
Population of UP = 1660 lakhs
Area of Rajasthan = 3 lakh$$km^2$$
Area of UP = 2 lakh $$km^2$$
(i) Number of people per $$km^2$$of Rajasthan = $$\frac{570 lakhs}{3 lakh km^2}$$= 190 per $$km^2$$
Number of people in UP = 1660 lakhs
Area of UP = 2 lakh$$km^2$$
Number of people per$$km^2$$of UP
= $$\frac{1660 lakhs}{2 lakh km^2} =830 per km^2$$
Since 190 per $$km^2$$< 830 per $$km^2$$
(ii) Rajasthan is less populated state.
