    If 15% of \[(A+B)=25%\] of \[(A-B).\] Then, what per cent of B is equal to A?

    A) 10%                             

    B) 60%

    C) 200%               

    D) 400%

    Correct Answer: D

    Solution :

    \[15%\,\,\text{of}\,\,(A+B)=25%\] of \[(A-B)\] \[\Rightarrow \] \[\frac{15\times (A+B)}{100}=\frac{25\times (A-B)}{100}\] \[\Rightarrow \] \[3A+3B=5A-5B\] \[\Rightarrow \] \[2A=8B\] \[\Rightarrow \] \[A=4B\] \[\Rightarrow \] 400% of B is equal to A.
