A) 0.5
B) 2
C) 50
D) 0.005
Correct Answer: C
Solution :
\[P\times \frac{50}{100}=Q\times \frac{25}{100}\] \[\Rightarrow \] \[P\times 50=Q\times 25\] \[\Rightarrow \] \[P=\frac{Q\times 25}{50}\] \[\Rightarrow \] \[P=\frac{Q}{2}\] \[P=Q\,\,\text{of}\,\,x%\] \[\therefore \] \[Q\times \frac{x}{100}=\frac{Q}{2}\] \[\Rightarrow \] \[x=\frac{100}{2}=50\]You need to login to perform this action.
