Step 1: Find the total score of all 8 students.
8 × 72 = 576
Step 2: Find the total score of the 6 remaining students.
6 × 75 = 450
Step 3: Find the total score of the 2 departed students.
576 − 450 = 126
Step 4: Find the average score of the 2 departed students.
126 ÷ 2 = 63
The average score of the 2 students who were dropped is 63.
Correct answer: 63
