    If 20% of A = 50% of B, then what per cent of A is B?

    A) 30%                             

    B) 40%

    C) 25 %                

    D) 15%

    Correct Answer: B

    Solution :

    20% of A = 50% of B \[\Rightarrow \]   \[2A=2B\] \[\Rightarrow \] \[A=\frac{5B}{2}\] Let B Is x % of A. \[\therefore \]      \[\frac{5B}{2}\times \frac{x}{100}=B\] \[\Rightarrow \]   \[x=\frac{200}{5}=40\]
