A dealer marks his goods 40% above the cost price. He sells 50% of the goods at the marked price, 25% at a 20% discount on the marked price, and the rest at a 40% discount on the marked price. What is his overall profit percentage? MCQ with Answer and Explanation

Let 100 items cost 10000. Marked Price = 140. 50 items sold at 140 = 7000. 25 items sold at 112 (140 * 0.8) = 2800. 25 items sold at 84 (140 * 0.6) = 2100. Total Selling Price = 7000 + 2800 + 2100 = 11900. Total Cost Price = 10000. Profit = 1900. Profit percentage = 19%.
