- To calculate the increase, first find the population at the end of one year by accounting for both birth and death rates.

- Initial population: 225,000

- Birth rate: 4.5% of 225,000 = 10,125

- Death rate: 2.5% of 225,000 = 5,625

- Net population increase in 1 year: 10,125 - 5,625 = 4,500

- Repeat the calculation for the second year.

- New population after 1 year: 225,000 + 4,500 = 229,500

- Births in second year: 4.5% of 229,500 = 10,327.5

- Deaths in second year: 2.5% of 229,500 = 5,737.5

- Net increase in second year: 10,327.5 - 5,737.5 = 4,590

- Total population increase after 2 years: 4,500 + 4,590 = 9,090

- Correct Option: 2, 9090
