What happens when Tricia pays P4,500 to Donna for personal debt?

When Tricia pays P4,500 to Donna for a personal debt, the full amount being applied to Donna's personal debt aligns with the principles of partnership law concerning the distinction between personal and partnership obligations. In partnerships, the debts are categorized based on whether they are personal obligations of the partners or obligations of the partnership itself.

In this scenario, since the payment is explicitly made toward Donna's personal debt and not for any partnership-related obligation, the payment does not involve any calculations or splits between different types of debts. Thus, the payment wholly satisfies Donna’s personal debt, showcasing that when a partner is addressing their debt, it does not directly interfere with the partnership’s financial obligations unless specified otherwise.

The other options suggest either a prioritization of partnership debts over personal debts or a splitting of payments, which would only apply if it were determined that the payment was intended to serve both debts or if no clear distinction existed regarding the debt's nature. However, since Tricia's payment is solely for Donna's personal debt, the correct understanding emphasizes that the entire amount is explicitly appropriated to that personal obligation.
