population in 2000= 20000(1+5/100)³
=(105/100)³×20000
=(11,57,625/1000000)×20000
=(11,57,625/100)×2
=11,57,625/50
=23,152.6

Answer:
population = 20,000
rate = 5%
therefore, ATQ
A= P (1 + R/100) n (compound interest formula used in this question)
A= 20000 (1 + 5/100)3
A= 20000 (20/20 + 1/20)3
A= 20000*21/20*21/20*21/20
A= 23152.5
