It is very important to look at all the details that are already given in the question. Only then the problem should be started for solving. Initial population of Memphis = 350000 population of Memphis after 1 year = 406000 Then Increase in population of Memphis in a year = 406000 - 350000 = 56000 Then Percentage increase in the population of Memphis in a year = (56000/350000) * 100 = (56 * 10)/35 = 560/35 = 16 percent So there is a 16% increase in the population of Memphis in a year.
