Worked Solution
Step 1: Recall the scoring rule — gold = 3 points, silver = 2 points, bronze = 1 point. Compute each class's total separately.
Step 2: 4A scored 4 × 3 + 5 × 2 + 2 × 1 = 12 + 10 + 2 = 24 points.
Step 3: 4B scored 6 × 3 + 3 × 2 + 4 × 1 = 18 + 6 + 4 = 28 points.
Step 4: 4C scored 5 × 3 + 4 × 2 + 3 × 1 = 15 + 8 + 3 = 26 points.
Step 5: 4D scored 3 × 3 + 6 × 2 + 5 × 1 = 9 + 12 + 5 = 26 points.
Step 6: Compare the totals: 24, 28, 26, 26. The highest is 28 points, which belongs to 4B.
Final answer: 4B.
