Partnership profit requires adjusting for capital changes Steps:

• Calculate ending net equity: capitals (20,000 + 10,000) + net currents (2,000 credit - 1,000 debit) = 31,000.
• Note beginning net assets (equity) = 12,000; increase = 31,000 - 12,000 = 19,000.
• Revaluation surplus = 2,000 (non-trading gain, added to equity).
• Increase = profit + revaluation + capital contributions (if any) - drawings (none).
• Capital contributions unknown, so profit cannot be isolated.

Why B is correct:

• Not applicable; calculation yields undetermined value.

Why the others are wrong:

• A, C, D: All assume specific (unjustified) capital contributions to reach these figures.
