Answer & Solution
Correct Answer:
Option
A
Population at the end of 2 years
= 189000 $$\left( {1 - \frac{8}{{100}}} \right)$$ $$\left( {1 + \frac{5}{{100}}} \right)$$
= $$\left( {189000 \times \frac{{23}}{{25}} \times \frac{{21}}{{20}}} \right)$$
= 182574
= 189000 $$\left( {1 - \frac{8}{{100}}} \right)$$ $$\left( {1 + \frac{5}{{100}}} \right)$$
= $$\left( {189000 \times \frac{{23}}{{25}} \times \frac{{21}}{{20}}} \right)$$
= 182574
