# the deer population in a forest grows at 4% per annum . if initially there were 45000 deers . find the number of deers after 2 years

it is given that there are 45000 deers

growth of dear per year =4%

so growth in first year = 4%of 45000 = $\frac{4}{100}\times 45000\phantom{\rule{0ex}{0ex}}4\times 450\phantom{\rule{0ex}{0ex}}1800$

so total deer after first year= 45000+1800=46800

so growth after second year= 4%of 46800 = 1872

so total deer after second year =46800+1872=48672
