A shopkeeper sells one-third of his goods at a profit of 10%, another one-third at a profit of 20%, and the rest at a loss of 6%. What is his overall profit percentage?

🧠 Explanation (Math):

Given: Sell 1/3 goods at +10%, 1/3 at +20%, 1/3 at −6%; overall profit?
Step 1: Assume each third costs C, so total cost = 3C
Step 2: Revenues = 1.10C, 1.20C, 0.94C
Step 3: Total revenue = (1.10 + 1.20 + 0.94)C = 3.24C
Step 4: Profit = 3.24C − 3C = 0.24C
Step 5: Profit% = 0.24C / 3C × 100 = 8%
Final Answer: 8%
