Answer 2

Answer:

the present population of the town is 57600

Step-by-step explanation:

population 2 years ago = 62500

rate of decrease = 4% per annum

∴ present population

= $62500 \times (1 - \frac{4}{100}) {}^{2}$

= $(62500 \times \frac{24}{25} \times \frac{24}{25}) = 57600$

Hence, the present population of the town is 57600
