  # Q.3 Population of Rajasthan = 570 lakhs and population of UP = 1660 lakhs. Area of Rajasthan = 3 lakh $$km^2$$ and area of UP = 2 lakh $$km^2$$. (i) How many people are there per $$km^2$$ in both these States? (ii) Which State is less populated?
  
  Population of Rajasthan = 570 lakhs
  Population of UP = 1660 lakhs
  Area of Rajasthan = 3 lakh$$km^2$$
  Area of UP = 2 lakh $$km^2$$
  (i) Number of people per $$km^2$$of Rajasthan = $$\frac{570 lakhs}{3 lakh km^2}$$= 190 per $$km^2$$
  Number of people in UP = 1660 lakhs
  Area of UP = 2 lakh$$km^2$$
  Number of people per$$km^2$$of UP
  = $$\frac{1660 lakhs}{2 lakh km^2} =830 per km^2$$
  Since 190 per $$km^2$$< 830 per $$km^2$$
  (ii) Rajasthan is less populated state.
