Answer 1

The correct answer is C

Answer 2

Answer:

Option(b)

Step-by-step explanation:

Let the population in 2022 will be x

Declining rate=2.2%

Population in 2016 year=3500

According to question

x=3500$(100-\frac{2.2}{100}$)^{6}

x=3500$(\frac{1000-22}{1000}$)^{6}

x=3500$(\frac{978}{1000}$)^{6}

x=3500.978^{6}

x=3063

Thus, correct answer is option(b)
