Answer 2

Answer:

Population after 3 Year =  138915

Step-by-step explanation:

Population of Village = 120000

Population increase 5 % every Year

Population after 1 Year = 120000 + (5/100)*120000

= 126000

Population after 2 Year = 126000 + (5/100)*126000

= 132300

Population after 3 Year = 132300 + (5/100)*132300

= 138915

Population after 3 Year =  138915
