A) \[55:29\]
B) \[36:17\]
C) \[33:14\]
D) \[16:11\]
Correct Answer: C
Solution :
\[\frac{8x-10y}{3x+4y}=\frac{4}{5}\] \[\Rightarrow \]\[5(8x-10y)=4(3x+4y)\] \[\Rightarrow \]\[40x-50y=12x+16y\] \[\Rightarrow \]\[28x=66y\] \[\Rightarrow \]\[\frac{x}{y}=\frac{66}{28}\] \[\Rightarrow \]\[x:y=33:14\]You need to login to perform this action.
