Question

Population of Rajasthan $=570$ lakhs and population of UP $=1660$ lakhs. Area of Rajasthan $=3$ lakh $k{m}^2$ and area of UP $=2$ lakh $k{m}^2$.
(i) How many people are there per $k{m}^2$ in both these States
(ii) Which state is less populated

Answer 1

The population of Rajasthan $=570\text{lakh}$

Area of Rajasthan $=3\text{lakh}k{m}^2$

population of Rajasthan per kilometer $=\frac{570\text{lakh}}{3\text{lakh}}=\frac{190}{1}$

The population in Rajasthan is $190$ people per $k{m}^2$.

Now,

Population of UP $=1660\text{lakh}$

Area of UP $=2\text{lakh}k{m}^2$

population of UP per kilometer $=\frac{1660\text{lakh}}{2\text{lakh}}=\frac{830}{1}$

Population in UP is $830$ people per kilometer square.

Hence, Rajasthan is less populated.
