A) 10% of y
B) 16% of y
C) 80% of y
D) 50% of y
Correct Answer: A
Solution :
\[\because \] \[8%\text{ of}\,x=4%\text{ }of\,y\] \[\Rightarrow \] \[\frac{8x}{100}=\frac{4y}{100}\] \[\Rightarrow \] \[2x=y\] \[\therefore \]\[20%\text{ of}\,x=20%\text{ of}\frac{y}{2}\] \[=\frac{20}{100}\times \frac{y}{2}\] \[=10%\text{ of }y\]You need to login to perform this action.
