A merchant allows a discount of 10% on marked price for the cash payment. To make a profit of 17%, he must mark his goods higher than their cost price by
Let Cost price = Rs. 100
Profit % = 17%
=> Selling price = $$100+(\frac{17}{100}\times100)$$
= $$100+17=Rs.$$ $$117$$
Discount % = 10%
=> Marked price = $$\frac{117}{(100-10)}\times100$$
= $$13\times10=Rs.$$ $$130$$
$$\therefore$$ Markup % = $$\frac{(130-100)}{100}\times100=30\%$$
=> Ans - (A)
