If the firm has guaranteed minimum profit to B, from where will B's deficiency be adjusted?

Correct answer: From profit distributable to other partners

Under a minimum-profit guarantee, the guaranteed partner must receive at least the promised amount. First, the partner’s actual share of profit is calculated according to the agreed profit-sharing ratio. If that share is lower than the guaranteed amount, the difference is called the deficiency. The deficiency is adjusted against the profit that would otherwise be distributed to the partners who have given the guarantee, normally in their agreed ratio unless the deed specifies another arrangement. It is not treated as B’s drawings, a bank borrowing, or a stock-account item. Therefore, option A is correct because the deficiency reduces the distributable profit of the other partners.
