Answer 2

Answer:

Step-by-step explanation:

Consider the population of 40-55 age group in Town A is = x

Given, Death rate (per thousand of population) of town A is = 21

Population of Town A is $=(30000+40000+x+10000)=(80000+x)$

Now as per population the no of death in Town A is = $\frac{21}{1000}\times(80000+x)$................... equation 1

Death rate (per thousand of population) between 0-15 age group in Town A is = 10

No of population in 0-15 age group in town A is =30000

therefore, No of death in the age group of 0-15 in town A is = $\frac{10}{1000}\times30000=300$

Death rate (per thousand of population) between 15-40 age group in Town A is = 20

No of population in 15-40 age group in town A is =40000

therefore, No of death in the age group of 15-40 in town A is = $\frac{20}{1000}\times40000=800$

Death rate (per thousand of population) between 40-55 age group in Town A is = 25

No of population in 40-55 age group in town A is =x

therefore, No of death in the age group of 40-55 in town A is = $\frac{25}{1000}\times{x}=\frac{25x}{1000}$

Death rate (per thousand of population) between 55 & above age group in Town A is = 50

No of population in 55 & above age group in town A is =10000

therefore, No of death in the age group of 55 & above in town A is = $\frac{50}{1000}\times10000=500$

Therefore total number of death in the town A is =$(300+800+\frac{25x}{1000}+500)=1600+\frac{25x}{1000}$.....................equation -2

Now compare the equation 1 and equation 2 we get

$1600+\frac{25x}{1000}=\frac{21}{1000}\times(80000+x)\\\\\Rightarrow1600+\frac{25x}{1000}=21\times80+\frac{21x}{1000}\\\\\Rightarrow1600+\frac{25x}{1000}=1680+\frac{21x}{1000}\\\\\Rightarrow\frac{25x}{1000}-\frac{21x}{1000}=1680-1600\\\\\Rightarrow\frac{4x}{1000}=80\\\\\Rightarrow{4x}=80\times1000\\\\\Rightarrow{x}=\frac{80\times1000}{4}=20000$

Therefore no of population in 40-55 age group in town A is =20,000

(ii)

Consider the Death rate (per thousand of population) of 55 & above age group population in Town B is = y

Given, Death rate (per thousand of population) of town B is = 14.66

Population of Town B is $=(40000+60000+30000+20000)=150000$

Now as per population the no of death in Town B is = $\frac{14.66}{1000}\times(150000)=2199</p><p>Death rate (per thousand of population) between 0-15 age group in Town B is = 20</p><p>No of population in 0-15 age group in town B is =40000</p><p>therefore, No of death in the age group of 0-15 in town B is = [tex]\frac{20}{1000}\times40000=800$

Death rate (per thousand of population) between 15-40 age group in Town B is = 15

No of population in 15-40 age group in town B is =60000

therefore, No of death in the age group of 15-40 in town B is = $\frac{15}{1000}\times60000=900$

Death rate (per thousand of population) between 40-55 age group in Town B is = 10

No of population in 40-55 age group in town B is =30000

therefore, No of death in the age group of 40-55 in town B is = $\frac{10}{1000}\times{30000}=300}$

Death rate (per thousand of population) between 55 & above age group in Town B is = y

No of population in 55 & above age group in town B is =20000

therefore, No of death in the age group of 55 & above in town B is = $\frac{y}{1000}\times20000=20y$

Therefore total number of death in the town B is =$(800+900+300+20y)=2000+20y}=2199\\\\\Rightarrow20y=2199-2000\\\\\Rightarrow=20y=199\\\\\Rightarrow=y=\frac{199}{20}\\\\\Rightarrow{y}=9.95=10$

Therefore  the Death rate (per thousand of population) of 55 & above age group population in Town B is = 10

Total population of town B is =$(40000+60000+30000+20000)=150000$

Total death of No of death in the age group of 55 & above in town B is = $\frac{10}{1000}\times20000=200$

Therefore, the total no of death of Town B is = $(800+900+300+200)=2200$

Standard death rate (per thousand of population) of Town B is = $=\frac{\text{No of death}}{\text{Total population}}\times1000=\frac{2200}{150000}\times1000= 14.6$

Therefore Standard death (per thousand of population) rate of Town B is = 14.6=15 (approx)
