    A got 30% concession on the label price of an article sold for Rs.8,750 with 25% profit on the price he bought. The label price was

    A)  10,000                       

    B)  13,000           

    C)         16,000             

    D)        12,000

    Correct Answer: A

    Solution :

    Let the labelled price be Rs. x Now. \[C.P.=\frac{100}{(100+profit\,%)}\times S.P\]             \[C.P.=\frac{100}{(100+25)}\times 8750=Rs.\,7000\] Now, (\[1-30%\]concession) label price = C.P             \[\left( 1-\frac{30}{100} \right)x=7000\]             \[\frac{70}{100}x=7000\]             \[x=\frac{7000\times 100}{70}\]             \[x=Rs.\,10,\,000\]
