Concept:For finding the population 'n' years ago: \(P=P_o\left [ 1\ +\ \frac{R}{100} \right ]^n\)where P = Total population at current, Po = Population 'n' years before or after, n = Time period, R = Rate per annum.Calculation:Given:P = 1102500, R = 5%, T = 2 years The population of the city 'n' years ago is given as:\(P=P_o\left [ 1\ +\ \frac{R}{100} \right ]^n\)\(1102500 =P_o \times\left [ 1\ +\ \frac{5}{100} \right ]^2\)Po = 10,00,000? The city's population 2 years ago is 10,00,000.Download Solution PDFShare on Whatsapp
