A tradesman marks his goods 30% more than the cost price, if he allows a discount of 20% on the marked price,then his gain percent is
Let cost price = Rs. 100
=> Marked price = $$100+(\frac{30}{100}\times100)$$
= $$100+30=Rs.$$ $$130$$
Discount % = 20%
=> Selling price = $$130-(\frac{20}{100}\times130)$$
= $$130-26=Rs.$$ $$104$$
$$\therefore$$ Profit % = $$\frac{(104-100)}{100}\times100=4\%$$
=> Ans - (D)
