A) 2 : 9
B) 7 : 2
C) 7 : 9
D) None of these.
Correct Answer: D
Solution :
[d] \[\frac{5x-3y}{5y-3x}=\frac{3}{4}\] \[\Rightarrow \] \[\frac{5-3\left( \frac{y}{x} \right)}{5\left( \frac{y}{x} \right)-3}=\frac{3}{4}\] \[\Rightarrow \] \[20-12\left( \frac{y}{x} \right)=15\left( \frac{y}{x} \right)-9\] \[\Rightarrow \] \[27\left( \frac{y}{x} \right)=29\Rightarrow \frac{y}{x}=\frac{29}{27}\]
