Population at the end of the second year = 40446


Find the population at the beginning of second year:

Percentage increase for the second year = 7%

Total percentage of the population = 100 + 7 = 107%

Total population = 40446

107% = 40446

1% = 40446 ÷ 107 = 378

100% = 378 x 100 = 37,800

Population at the beginning of second year = 37,800


Find the population at the beginning of first year:

Percentage increase for the second year = 5%

Total percentage of the population = 100 + 5 = 105%

Total population =  37,800

105% = 37,800

1% = 37800 ÷ 105 = 360

100% = 360 x 100 = 36000

Population at the beginning of first year = 36,000


Answer: The population at the beginning is 36,000
