According to the question, (3000 × 12) : [2000 × (12 – x)] = (8250 – 2250) : 2250 → 36000 : [2000 × (12 – x)] = 6000 : 2250 → 36000 / [2000(12 – x)] = 6000 / 2250 Cross-multiplying: 36000 × 2250 = 6000 × 2000 × (12 – x) Simplify: 36000 / 2000 = 6000 / (12 – x) → 18 = 6000 / (12 – x) → 18(12 – x) = 6000 → 216 – 18x = 6000 → x = 4
