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

dear student,

it is given that  there are 45000 deers
growth of dear per year =4%
so growth in first year = 4%of 45000 = $$\begin{gathered} \frac{4}{100}\times 45000 \\ 4\times 450 \\ 1800 \end{gathered}$$


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
