Explanation

Approximating: 20300 ≈ 20000, 36.14 ≈ 36, 176.120 ≈ 176, 38.72 ≈ 39. So: (20000/36)×176 ≈ 555.56×176 ≈ 97778. Then 97778 - 39 ≈ 97739, which rounds to approximately 100000. The exact calculation: 20300÷36.14 × 176.120 - 38.72 ≈ 561.8×176.12 - 38.72 ≈ 98963 - 38.72 ≈ 98924, closest to 100000 among options.
