If x/y = 4/5 , then the value of ( 4/7 + 2y - x2y + x ) is?

Answer: Option C

$$\begin{array}{rl}& \frac{x}{y}=\frac{4}{5}\\ & \frac{4}{7}+\frac{2y-x}{2y+x}\\ & =\frac{4}{7}+\frac{y\left(2-\frac{x}{y}\right)}{y\left(2+\frac{x}{y}\right)}\\ & =\frac{4}{7}+\frac{\left(2-\frac{4}{5}\right)}{\left(2+\frac{4}{5}\right)}\\ & =\frac{4}{7}+\frac{10-4}{10+4}\\ & =\frac{4}{7}+\frac{6}{14}\\ & \text{ = }\frac{8+6}{14}\\ & \text{ = }\frac{14}{14}\\ & \text{ = 1}\end{array}$$
