=> 103 % of 18000

Now ,

Population At the second year

=> 103% of Innitial Population

=> 103 % of [ 103 % of 18000 ]

Now ,

Population At the third year

=> 103% of Innitial Population

=>103 % of { 103 % of [ 103 % of 18000 ] }

Now ,

Population After 4 years

=> 103% of Innitial Population

=>103 % of 103 % of { 103 % of [ 103 % of 18000 ] }

=> 20260 Approximately .
