The marked price of an item is twice the cost price, discount 20% of market price and profit is 10% of selling price. Find profit percentage to cost

Answer: Option A

Given,
MP = Rs. 200
Discount = 20%
Profit = Rs. 16
SP = 200 - 20% of 200 = 200 - 40 = Rs. 160
CP = SP - profit = 160 - 16 = Rs.144
% profit = $$\frac{16\times 100}{144}=11.11\%=\frac{100}{9}\%$$
