Solution

The correct option is B $495$
$\Rightarrow$ Investment decreases 10% in first year.
$\Rightarrow$ Investment for 1st year = $$ (500 - 500 \times \frac{10}{100}) = $ 500 - $ 50 = $ 450$ .
$\Rightarrow$ Investment increases 10% in second year.
$\Rightarrow$ Investment for 2 years = $$ (450 + 450 \times \frac{10}{100}) = $ 450 + $ 45 = $ 495$ .
$∴$ Investment after 2 years will be $$ 495$ .
