Explanation

To solve 912.898 - 27.001 × ? - 288.878 = 219.003, first rearrange: 912.898 - 288.878 - 219.003 = 27.001 × ?. This gives 405.017 = 27.001 × ?, so ? = 405.017 ÷ 27.001 ≈ 15.0006. Approximating to the nearest integer gives 15, which is option C. The other options (23, 18, 24, 21) don't satisfy the equation.
