    A) 120%

    B)  60%

    C)  100%

    D)  200%

    Correct Answer: A

    Solution :

    Let the selling price be Rs. 100. \[\therefore \] Cost price \[=\frac{SP\times 100}{(100+10)}=\frac{100\times 100}{110}\] = Rs.\[\frac{1000}{11}\] Now, if selling price is Rs. 200 \[\therefore \] Gain = Rs. \[\left( 200-\frac{1000}{11} \right)\]= Rs. \[\frac{1200}{11}\] Gain per cent\[=\frac{1200/11}{1000/11}\times 100=120%\]
