Given,
Growth rate of population of town = \(\frac{50}{1000}\times100\) = 5%
Population after 2 years = 22050
Let present population of town = X
So,
\(x\times({1}+\frac{5}{100})({1}+\frac{5}{100})\) = 22050
\(x\times\frac{21}{20}\times\frac{21}{20}\) = 22050
\(=x=\frac{22050 \times 20 \times 20}{441}\) = 20000
Hence,
Present population of town = 20000
