Question

the population of a city was 20000 in the year 1997.it increased at the rate of 5%p.a. find the population at the end of the year 2000

Answer 1

The answer is 2315,because the population increases every year,so,in 1998 the population is 5/100*20,000. The answer is 21,00
the population in 1998=21,00
population in 1999=5/100*21000
                                =22050
population in 2000=5/100*22050
                                 =2315.25
Thus the answer=2315.25
The answer sounds funny but that is the answer
