    A dealer sold a mixer for Rs.420 at a loss of 12.5%. At what price should he have sold it to gain 12.5%.

    A)  Rs.620                         

    B)  Rs.540             

    C)  Rs.650              

    D)         Rs.750             

    Correct Answer: B

    Solution :

    \[(100-loss):{{S}_{1}}::(100+gain):{{S}_{2}}\] \[\therefore \]  \[(100-12.5):420::(100+12.5):{{S}_{2}}\] \[875:420\,:\,:1125:{{S}_{2}}\] \[\Rightarrow \]   \[87.5\times {{S}_{2}}=420\times 112.5\] \[\Rightarrow \]   \[{{S}_{2}}=\frac{420\times 1125}{875}=540\]
