Final answer:
After Charles' withdrawal from the partnership and the $100,000 distribution, the remaining total capital is divided equally between Arthur and Beatrice. Arthur's capital account balance would then be $250,000.
Step-by-step explanation:
To determine the balance in Arthur's capital account after Charles' withdrawal from the ABC Partnership and the distribution of $100,000, it is essential to understand that the partners share equally in profits and losses.
Prior to Charles leaving, the total capital for the partnership is $600,000 ($150,000 + $350,000 + $100,000).
Since Charles withdraws his capital of $100,000, the new total capital is $500,000. No additional information about profit or loss allocation or the partnership agreement following the withdrawal is provided, so it is assumed that the remaining capital is still shared equally between Arthur and Beatrice.
When Charles withdraws his $100,000, the partnership capital is divided equally between Arthur and Beatrice, the remaining partners. This results in each partner having a new capital balance of $250,000 ($500,000 total capital divided by 2). Hence, Arthur's capital account balance after the transaction would be $250,000.
