A) \[\frac{3}{7}\]
B) 1
C) \[1\frac{1}{7}\]
D) 2
Correct Answer: B
Solution :
\[\because \frac{x}{y}=\frac{4}{5}\] \[\therefore \]\[\frac{4}{7}+\frac{2-x/y}{2+x/y}=\frac{4}{7}+\frac{2-4/5}{2+4/5}\] \[=\frac{4}{7}+\frac{6}{5}\times \frac{5}{14}=\frac{4}{7}+\frac{3}{7}=1\]You need to login to perform this action.
