The marked price of a trouser is twice of the cost price. To earn 36% profit, what should be the value of discount (in percentage)?
Let cost price = Rs. $$100x$$
=> Marked price = $$2\times100x=Rs.$$ $$200x$$
Profit % = 36%
=> Selling price = $$100x+(\frac{36}{100}\times100x)=Rs.$$ $$136x$$
$$\therefore$$ Discount % = $$\frac{(200x-136x)}{200x}\times100$$
=> $$\frac{64}{2}=32\%$$
=> Ans - (B)
