Answer:

21856

Step-by-step explanation:

25% rise in population of 18700 in year one = 25×18700/100

∆P=4675

new population P = p+∆p=23375

∆p2=10×23375/100=2337.5 approx 2338

new population P2=25713

∆p3=15×25713/100=3857approx

new population P3=P2-∆p3(fall in population)

P3=25713-3857=21856
