    If a commission of 10% is given on the written price, the gain is 50%. What shall be the percentage of gain, if the commission is increased to 25%?

    A) 20                                     

    B) 22

    C) 25                                     

    D) 26

    Correct Answer: C

    Solution :

    Let M.P. = Rs. 100 Commission = Rs.10 So, S.P. = Rs.90 So,  \[C.P.=\frac{100\times 90}{150}=Rs.\,60\] If commission is 25%, then S.P. = 75 So, gain% \[C.P.=\frac{100\times 90}{150}=Rs.\,60\]
