(d)41.4
Answer
Explanation
Given expression $$\begin{aligned} & =35.7-\left(3+\frac{1}{\frac{10}{3}}\right)-\left(2+\frac{1}{\frac{5}{2}}\right)=35.7-\left(3+\frac{3}{10}\right)-\left(2+\frac{2}{5}\right) \\ & =35.7-\frac{33}{10}-\frac{12}{5}=35.7-\left(\frac{33}{10}+\frac{12}{5}\right) \\ & =35.7-\frac{57}{10}=35.7-5.7=30 . \end{aligned}$$
