Question 13

The marked price of a helmet is 30% more than its cost price. If the helmet is sold for Rs 744 after a discount of Rs 36, then what will be the profit percentage?

Solution

Let cost price = Rs. $$100x$$

=> Marked price = $$100x+(\frac{30}{100}\times100x)=Rs.$$ $$130x$$

Selling price = Rs. 744

=> Discount amount = $$130x-744=36$$

=> $$130x=36+744=780$$

=> $$x=\frac{780}{130}=6$$

Thus, cost price = $$100\times6=Rs.$$ $$600$$

$$\therefore$$ Profit % = $$\frac{(744-600)}{600}\times100$$

= $$\frac{144}{6}=24\%$$

=> Ans - (A)
