Partnership profit calculated from current account changes, but missing data Steps:

• Net change in X's current account: opening credit $12,000 to closing debit$17,000 = $29,000 decrease.
• X's transactions: salary credit $5,000, drawings debit$13,000 = net $8,000 decrease.
• X's share of remaining profit after salary: $29,000 total decrease -$8,000 net = $21,000 decrease (negative share).
• Total profit P = salary $5,000 + shares (X + Y); requires Y's closing balance and sharing ratio to solve for Y's share.
