Question 13

Rohit wants to earn 21% profit on a belt after offering 45% discount. By how much percentage more should he mark the price of his article above the cost price?

Solution

Let marked price of article = Rs. $$100x$$

Discount % = 45%

=> Selling price = $$100x-(\frac{45}{100}\times100x)=Rs.$$ $$55x$$

Profit % = 21%

=> Cost price = $$\frac{55x}{100+21}\times100=Rs.$$ $$\frac{500x}{11}$$

$$\therefore$$ Required % = $$\frac{100x-\frac{500x}{11}}{\frac{500x}{11}}\times100$$

= $$\frac{1100-500}{5}=\frac{600}{5}=120\%$$

=> Ans - (B)
