Answer 1

Population of Rajasthan $=570$ lakh

area of rajasthan $=3$ lakh $k{m}^2$

Population of UP $=1660$ lakh

are of UP $=21$ lakh $k{m}^2$

$\left(i\right)$ number of people per $k{m}^2$ in Rajasthan $=\frac{Population}{area}$

$=\frac{510lakh}{36lakh}$

no of people per $k{m}^2$ in Rajasthan $=190$ people $k{m}^2$

no of people in UP per $k{m}^2=\frac{Population}{area}$

$=\frac{1660}{2}$

no of people in UP per $k{m}^2=830peoplek{m}^2$

$\left(ii\right)$ Rajastha is less populated line

no of people per $k{m}^2$ of Rajasthan $<$ no of people per $k{m}^2$

in UP.
