    If goods be purchased for Rs. 450 and one third sold at a loss of 10% At what gain percent should the remainder be sold so as to gain 20% on the whole transaction?

    A) 32%                             

    B) 35%

    C) 28%                             

    D) 30%

    Correct Answer: B

    Solution :

    Let the required gain % = \[x.\] \[\therefore \,\,\,150\times \frac{90}{100}+300\times \frac{(100+x)}{100}=\frac{450\times 120}{100}\] \[\Rightarrow 135+3\,(100+x)=540\] \[\Rightarrow 3\,(100+x)=540-135=405\] \[\therefore \] \[100+x=\frac{405}{3}=135\] \[\Rightarrow x=135-100=35%\]
