Simplify : - 1/2 - 2/3 + 4/5 - 1/3 + 1/5 + 3/41/2 + 2/3 - 4/3 + 1/3 - 1/5 - 4/5

Answer: Option A

$$\begin{array}{rl}& \text{Given expression,}\\ & \frac{\left(-\frac{2}{3}-\frac{1}{2}\right)+\left(\frac{4}{5}+\frac{1}{5}\right)+\left(\frac{3}{4}-\frac{1}{2}\right)}{\left(\frac{2}{3}-\frac{4}{3}+\frac{1}{3}\right)-\left(\frac{1}{5}+\frac{4}{5}\right)+\frac{1}{2}}\\ & =\frac{-1+1+\frac{1}{4}}{-\frac{1}{3}-1+\frac{1}{2}}\\ & =\frac{\frac{1}{4}}{\frac{-2-6+3}{6}}\\ & =\frac{\frac{1}{4}}{-\frac{5}{6}}\\ & =\frac{1}{4}\times \left(-\frac{6}{5}\right)\\ & =-\frac{3}{10}\end{array}$$
