    If 90% of A = 30% of B and B = 2 x% of A, then the value of x is

    A) 450      

    B)  400     

    C)  300

    D)  150

    Correct Answer: D

    Solution :

    90% of A = 305 of B \[\therefore \]      \[A\times \frac{90}{100}=B\times \frac{30}{100}\] \[\Rightarrow \]   \[3A=B\] \[\therefore \]      \[B=2x%\] of \[A\] \[\Rightarrow \]   \[3A=A\times \frac{2x}{100}\]\[\Rightarrow \]\[x=\frac{3\times 100}{2}=150\]
