Solve this : (0.85% of 405) + (2.25% of 550) = ?

Answer: Option E

$$\left(0.85\%\text{ of }405\right)+\left(2.25\%\text{ of }550\right)$$
$$=\left(\frac{85}{100}\times \frac{1}{100}\times 405\right)+$$     $$\left(\frac{225}{100}\times \frac{1}{100}\times 550\right)$$
$$\begin{array}{rl}& =\frac{225}{10000}\left(153+550\right)\\ & =\left(\frac{225\times 703}{10000}\right)\\ & =15.8175\end{array}$$
