7. The population of State A is 760 lakh and the population of State B is 1660 lakh. If the area of State A is 4 lakh km² and the area of State B is 2 lakh km²,

(a) How many people are there per km² in both states?
(b) Which state is more densely populated?



Answer :

Sure, let's begin solving the problem step by step.

### (a) Determine the population density for each state

The population density is defined as the number of people per square kilometer:

[tex]\[ \text{Population Density} = \frac{\text{Population}}{\text{Area}} \][/tex]

#### Population Density of State A
- Population of State A: 760 lakh
- Area of State A: 4 lakh km²

[tex]\[ \text{Density of State A} = \frac{760 \text{ lakh}}{4 \text{ lakh km}^2} = 190 \text{ people per km}^2 \][/tex]

#### Population Density of State B
- Population of State B: 1660 lakh
- Area of State B: 2 lakh km²

[tex]\[ \text{Density of State B} = \frac{1660 \text{ lakh}}{2 \text{ lakh km}^2} = 830 \text{ people per km}^2 \][/tex]

So, the population densities are:
- State A: 190 people per km²
- State B: 830 people per km²

### (b) Determine which state is more populated in terms of population density

To determine which state is more populated in terms of population density, we compare the two densities obtained:

- State A: 190 people per km²
- State B: 830 people per km²

Since 830 people per km² (State B) is greater than 190 people per km² (State A),

State B is more densely populated than State A.

### Summary:
(a) Population density:
- State A: 190 people per km²
- State B: 830 people per km²

(b) State B is more populated in terms of population density.
