Given:
- Present population of the town = 25000
- Growth rate in the first year = 4%
- Growth rate in the second year = 5%
- Growth rate in the third year = 8%

To find:
- Population after 3 years

Solution:
To find the population after 3 years, we need to calculate the population growth for each year and add it to the initial population.

Year 1:
Population growth in the first year = 4% of 25000
= (4/100) * 25000
= 1000

Population after the first year = Initial population + Population growth in the first year
= 25000 + 1000
= 26000

Year 2:
Population growth in the second year = 5% of 26000
= (5/100) * 26000
= 1300

Population after the second year = Population after the first year + Population growth in the second year
= 26000 + 1300
= 27300

Year 3:
Population growth in the third year = 8% of 27300
= (8/100) * 27300
= 2184

Population after the third year = Population after the second year + Population growth in the third year
= 27300 + 2184
= 29484

Therefore, the population after 3 years is 29484 (option A).
