Question

Population of Rajasthan is $570lakh$ and population of UP is $1660lakh$.

Area of Rajasthan is $3lakh$/$k{m}^2$ and area of UP is $2lakh$/$k{m}^2$

$\left(i\right)$ How many people are there per $k{m}^2$ in both these states?

$\left(ii\right)$ Which State is less populated?

Answer 1

$\left(i\right)$ Population of Rajasthan $=570lakh$

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

Number of people in Rajasthan per $1k{m}^2$ area $=\frac{57000000}{300000}$ $=190$

Which means $190$ people are there per $k{m}^2$ in Rajasthan.

Population of U.P $=1660$ lakh

Area of U.P $=2lakh$/$k{m}^2$

Number of people in Rajasthan per $1k{m}^2$ area $=\frac{1660}{3}$ $=830$

Which means $830$ people are there per $k{m}^2$ in U.P.

$\left(ii\right)$ From $\left(i\right)$,

$190$ people are there per $k{m}^2$ in Rajasthan.

$830$ people are there per $k{m}^2$ in U.P.

It can be observed that population per $1k{m}^2$ area of U.P is lesser for Rajasthan.

Therefore, Rajasthan is less populated.
