(i) How many people are there per km² in both these States?
(ii) Which State is less populated?

Solution:

In Rajasthan, Number of people per km² = Population / Area 

= 570,00,000 / 3,00,000

= 190

It means 190 people are there per km² in Rajasthan.

In UP., Number of people per km²

= 1660,00,000 / 2,00,000

= 830

It means 830 people are there per km² in UP

(ii ) Rajasthan is less populated because in Rajasthan fewer people live per km² as compared to UP.
