    If selling price of an article is \[\frac{4}{3}\] of its cost price, the profit in the transaction is:

    A)  \[16\frac{2}{3}%\]               

    B)  \[20\frac{1}{2}%\]

    C)  \[25\frac{1}{2}%\]   

    D)           \[33\frac{1}{3}%\]

    Correct Answer: D

    Solution :

     \[S=\frac{4}{3}C,\,\frac{S}{C}=\frac{4}{3}\] Profit% \[=\left( \frac{S-C}{C} \right)\times 100=\left( \frac{S}{C}-1 \right)\times 100\] \[=\left( \frac{4}{3}-1 \right)\,(100)=\frac{100}{3}\,=33\frac{1}{3}%\]
