480,000
249,696
249,600
244,800
Penjelasan
1st year, Population = 240,000 x (\(\frac{2}{100}\)) = 4800.
Being the 2nd year population = 240,000 + 4800 = 244800.
Increase in Pop. in 2nd year = 244800 x (\(\frac{2}{100}\)) = 4896
Jan 2000, Pop. = 244800 + 4896 = 249,696
Being the 2nd year population = 240,000 + 4800 = 244800.
Increase in Pop. in 2nd year = 244800 x (\(\frac{2}{100}\)) = 4896
Jan 2000, Pop. = 244800 + 4896 = 249,696
