A) 7 : 32
B) 32 : 7
C) 4 : 3
D) 5 : 2
Correct Answer: B
Solution :
\[\frac{x}{y}=\frac{3}{4}\text{(Given)}\] \[\therefore \] \[\frac{4x+5y}{5x-2y}=\frac{4\frac{x}{y}+5}{5\frac{x}{y}-2}\] \[=\frac{4\frac{3}{4}+5}{5\times \frac{3}{4}-2}=\frac{8}{\frac{15-8}{4}}=\frac{8\times 4}{7}=\frac{32}{7}\]You need to login to perform this action.
