🧠 Explanation:
School strength increased from 550 to 616 after 12% growth. “Increased” is a verb; “strength” is a noun. Calculation: 550 × 0.12 = 66; 550 + 66 = 616. Alternatives like “enrollment” could be used. Learning percentage growth and arithmetic is important in math and statistical reasoning.
