Explanation

Calculate: (250.87 × 8.12 × 6.829) ÷ 25 = ? × 11.86. Approximation: (251 × 8.1 × 6.8) ÷ 25 ≈ 251 × 8.1 × 0.272 ≈ 251 × 2.2 ≈ 552. Then 552 - 11.86 ≈ 540. Option C (548) is closest. Precise calculation: 250.87 × 8.12 = 2037.0664, then × 6.829 = 13911.47, then ÷ 25 = 556.46. Then 556.46 - 11.86 = 544.6. Option C (548) is closest.
