The value of [ 35.7 - ( 3 + 13 + 1/3 ) - ( 2 + 12 + 1/2 ) ] is :

Answer: Option A

Given expression :
$$\begin{array}{rl}& =35.7-\left(3+\frac{1}{\frac{10}{3}}\right)-\left(2+\frac{1}{\frac{5}{2}}\right)\\ & =35.7-\left(3+\frac{3}{10}\right)-\left(2+\frac{2}{5}\right)\\ & =35.7-\frac{33}{10}-\frac{12}{5}\\ & =35.7-\left(\frac{33}{10}+\frac{12}{5}\right)\\ & =35.7-\frac{57}{10}\\ & =35.7-5.7\\ & =30\end{array}$$
