    At what per cent above the cost price, must a shopkeeper marks his goods so that he gains 20% even after giving a discount of 10% on the marked price?

    A)  \[25%\]

    B)  \[30%\]

    C)  \[33\frac{1}{3}%\]

    D)  \[37\frac{1}{2}%\]

    Correct Answer: C

    Solution :

    Let the CP be Rs. 100. Then, SP = Rs. 120 Let the marked price be Rs. x. Then, 90% of x = 120 \[\Rightarrow \]   \[x=\frac{120\times 100}{90}=\frac{400}{3}=133=\frac{1}{3}%\] It means he should mark\[33\frac{1}{3}%\] higher than CP.
