Ambiguous partnership details prevent precise calculation Steps:

• Identify partnerships: XZ (ratio 2:1) and XY (ratio 2:1), but unclear which has the $15,000 profit.
• Note Y's $500 loan interest and X's$10,000 salary, but unspecified to which partnership.
• Attempt standard appropriation for XY: deduct $500 interest and$10,000 salary from $15,000, leaving$4,500; Y's 1/3 share = $1,500 +$500 = $2,000 (mismatches options).
• Alternative for XYZ (inferred ratio 2:1:1): deduct $500 +$10,000, leaving $4,500; Y's 1/4 share =$1,125 + $500 =$1,625 (mismatches). Not enough information.

Final answer: Not enough information.
