Step-by-step explanation:
Here, The population of the city in the year 1997, P = 20000
The rate of increase in the population, R = 5% p.a.
Time , n = 3 years
Therefore, The population of the city in the year 2000, A = P(1- R/100)n
= 20000(1+ 5/100)³
= 20000(1+ 1/20)³
= 20000(21/20)³
= (20000× 21/20×21/20×21/20)
= 23152.5
Hence, The required population of the city in the year 2000 = 23152.5
