Answer & Solution
Correct Answer:
Option
D
Population after 2 years :
$$\eqalign{ & = 8500 \times \left( {1 + \frac{{20}}{{100}}} \right)\left( {1 + \frac{{25}}{{100}}} \right) \cr & = \left( {850 \times \frac{6}{5} \times \frac{5}{4}} \right) \cr & = 12750 \cr} $$
$$\eqalign{ & = 8500 \times \left( {1 + \frac{{20}}{{100}}} \right)\left( {1 + \frac{{25}}{{100}}} \right) \cr & = \left( {850 \times \frac{6}{5} \times \frac{5}{4}} \right) \cr & = 12750 \cr} $$
