A) \[25%\]
B) \[33\frac{1}{3}%\]
C) \[40%\]
D) \[400%\]
Correct Answer: A
Solution :
\[\frac{30}{100}(x+y)=\frac{50}{100}(x-y)\] \[\Rightarrow \] \[30x+30y=50x-50y\] \[\Rightarrow \] \[80y=20x\] \[\Rightarrow \] \[y=\frac{20}{80}x=\frac{1}{4}x\] \[\Rightarrow \] y is 25% of x.You need to login to perform this action.
