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?

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.
