Explanation

Set up equation: 63251 × 82 = ? × 42105. Calculate LHS: 63251 × 82 ≈ 63000 × 82 = 5,166,000. Then ? = 5,166,000 ÷ 42105 ≈ 123, closest to 125. More precisely: 63251 × 82 = 5,186,582. Divide by 42105: 5,186,582 ÷ 42,105 ≈ 123.2. Option C (125) is the closest. The calculation requires careful multiplication and division.
