A Correct answer
Explanation

Total weight of 10 girls = 10 * 40 = 400 kg. After one girl leaves, 9 girls remain with an average of 40 - 2 = 38 kg. Total weight of 9 girls = 9 * 38 = 342 kg. Weight of the girl who left = 400 - 342 = 58 kg. Since 58 > 48, Quantity I > Quantity II.

AI explanation

Using the average formula, the total weight of the 10 girls is 10 multiplied by 40, which equals 400 kg. When one girl leaves, the total weight of the remaining 9 girls is 9 multiplied by 38, giving 342 kg. The weight of the girl who left is the difference 400 minus 342, which is 58 kg; since 58 kg is greater than 48 kg, Quantity I is greater than Quantity II.
