Answer:
The population of the city in the year 2025 will be 85,000.
Step-by-step explanation:
The population of the city in year 2005 = 15,000
The population of the city in the year 2015 = 45,000
⇒ The change in population in 10 years
= Population in year 2015 - Population in the year 2005
= 45,000 - 15, 000
= 30,000
⇒ The change in population in 10 years = 30,000
Now, the population in the year 2015 = 45, 000
Let us assume the number of population in the year 2025 = m
Here, according to the question:
Since, the CHANGE OF RATE is a linear growth since 2005.
⇒ The change in population in each 10 years = 30,000
⇒ The change in population in next 10 years
= Population in year 2025 - Population in the year 2015
or, 30, 000 = m - 45, 000
⇒ m = 30,000 + 45,000 = 85,000
or, m = 85,000
Hence, the population of the city in the year 2025 will be 85,000.
