For China: 1,545,744,200

For Mexico: 145,507,500

For Zaire: 92,237,875

Step-by-step explanation:

For Australia: Population in 2000 is 19,169,000 and it is increasing steadily at a rate of 0.6% per year.

Therefore, the population in the year 2025 will be  

19169000[1+\frac{0.6 \times 25}{100} ]= 22,044,350 (Answer)

For China: Population in 2000 is 1,261,832,000 and it is increasing steadily at a rate of 0.9% per year.

Therefore, the population in the year 2025 will be  

1261832000[1+\frac{0.9 \times 25}{100} ]= 1,545,744,200 (Answer)

For Mexico: Population in 2000 is 100,350,000 and it is increasing steadily at a rate of 1.8% per year.

Therefore, the population in the year 2025 will be

100350000[1+\frac{1.8 \times 25}{100} ]= 145,507,500 (Answer)

For Zaire: Population in 2000 is 51,965,000 and it is increasing steadily at a rate of 3.1% per year.

Therefore, the population in the year 2025 will be

51965000[1+\frac{3.1 \times 25}{100} ]= 92,237,875 (Answer)
