Answer:

After 7 months population will be same.

(43425 + 75x) = (45000 - 150x)

Step-by-step explanation:

Population of a town = 43425.

Number of people moving out of the town = 125 per month

Number of people moving in = 200 per month

On an average number of people increasing every month = 200 - 125

                                                                                                = 75

Population of the nearby town = 45000

Number of people moving in = 0 per month

Number of people moving out = 150 per month

Let after x months number of population will be same.

So the equation will be (43425 + 75x) = (45000 - 150x)

1). By solving this equation we can get the number months when the population of both the towns will be same.

43425 + 75x = 45000 - 150x

43425 + 75x + 150x = 45000

75x + 150x = 45000 - 43425

225x = 1575

x = 1575/225

x = 7 months
