While selling, a businessman allows 40% discount on the marked price and there is a loss of 30%. If it is sold at the marked price, profit percent will be

Let the marked price be Rs 100. Let the Cost price be Rs x.

A/c to question ,a businessman allows 40% discount on the marked price and there is a loss of 30%,

60 = $$\frac{70}{100}x$$

x = $$\frac{600}{7}$$

If it is sold at marked price , 

Profit = $$100 - \frac{600}{7} = \frac{100}{7}$$

Profit % = $$\frac{\frac{100}{7}}{\frac{600}{7}}  \times 100 = \frac{50}{3}$$

So, the answer would be option c)16$$\frac{2}{3}$$ %
