    B) \[16\frac{4}{6}%\]

    C) 18%                             

    D) \[8\frac{2}{6}%\]

    Correct Answer: A

    Solution :

    We know that if the cost price of x articles equals the selling price of w articles, then profit percentage \[=\frac{x-w}{w}\times 100%\] Here,     \[x=36,\] \[w=30\] \[\therefore \]      Profit percentage \[=\frac{36-30}{30}\times 100%\]             \[=\frac{600}{30}%=20%\]
