Answer 1

Answer:

Population after 2 years = 3,11,040

Step-by-step explanation:

Present population = 2,16,000

We know the it is increasing 20% each year,

⟹ 1 st year = 2,16,000 × 20 / 100

⟹ 43,200

Population after increase (1 st year) = Original population + 1 st year's increase

⟹ 2,16,000 + 43,200

⟹ 2,59,200

Second year's population will increase from the first year's population,

⟹ ∴ 2 nd year = 2,59,200 × 20 / 100

⟹ 51,840

Population after increase (2 nd year) = 1 st year's population + 2 nd year

⟹ 2,59,200 + 51,840

⟹ 3,11,040

• ∴ The population after 2 years = 3,11,040
