Explanation

Approximate and solve: Left side: 15% of (16.01)² + (12.01)³ ≈ 0.15 × 256 + 1728 ≈ 38.4 + 1728 ≈ 1766.4. Right side: ? × (14% of 198.78) × (22.99 + 17.01) ≈ ? × 27.83 × 40 ≈ ? × 1113.2. Equation: 1766.4 ≈ ? × 1113.2, so ? ≈ 1.59. Rounding to nearest integer gives 2. Option A is correct.
