Q. While selling to the retailer, a company allows 30% discount on the marked price on their products. If the retailer sells those products at marked price, his profit % will be:
Answer: $latex 42\frac{6}{7}\%&s=1$
Notes: If the marked price of the product be 100 Rs., then C.P. = 70 Rs. S.P. retailer = 100 Rs. ∴ Gain per cent = $latex = \frac{30}{70}\times 100 = \frac{300}{7}&s=1$ $latex = 42\frac{6}{7}\%&s=1$ Hence option [C] is the right answer.
