A B and C share profits in (5:4:3). D gets (1/6) share and D's share is sacrificed by all old partners in old ratio. What will be the new ratio?

Answer and explanation

Correct answer: A B C D (25:20:15:12)

Direct answer: The new ratio is A:B:C:D = 25:20:15:12, so option A is correct. The old partners together retain \(1−1/6=5/6\), because D receives \(1/6\). D's share is sacrificed by all old partners in their old ratio 5:4:3. Their fractional parts of the old total are 5/12, 4/12, and 3/12. Thus A gets \(5/6×5/12=25/72\), B gets \(5/6×4/12=20/72\), and C gets \(5/6×3/12=15/72\). D gets \(1/6=12/72\). Hence 25:20:15:12. Option A is correct. B wrongly leaves old shares unchanged. C multiplies old shares without reducing them. D gives incorrect old-partner amounts. Use: retained share × old ratio fraction.
