In the given problem, there are several vital informations that have been provided. based on these information's the answer to the asked question can be easily reached. It is given that the initial population of the town is 4500. It doubles in every 10 years. The number of population in 12 years is needed to be found.
Initial population of the town = 4500
In 10 years the population of the town = 4500 * 2

Then population of the town in 12 years = (9000/10) * 12
