    B) 40      

    C) 50                                

    D) 70

    Correct Answer: D

    Solution :

    CP of 50 pens \[=50\times 50=Rs.\,2500\] For profit of 10%             \[SP=\frac{2500\times 110}{100}=Rs.\,2750\] SP of 40 pens at a loss of 5%             \[=\frac{40\times 50\times 95}{100}=Rs.\,1900\] SP of 40 remaining 10 pens \[=2750-1900=Rs.\,850\] \[\therefore \]      Gain percentage \[=\frac{850-500}{500}\times 100=70\]
