Given that,
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}

Now, 

(a) Number of peoples per km^2 
In Rajsthan, = \frac{population}{area}
                       =\frac{570}{3}= 190

In UP, 
\frac{population}{area} = \frac{1160}{2}
                          = 580  

(b) Rajasthan is less populated as we can see that the number of people in per km^2 is less
