A and B shared profits in the ratio 4:1. After the admission of a new partner, the new profit-sharing ratio of A, B and the new partner became 3:1:1 respectively. Which old partner made no sacrifice?

Correct answer: B

B’s old profit share was \(1/5\), and its share in the new ratio is also \(1/5\). Thus, B’s share did not decrease, so B made no sacrifice. In contrast, A’s share fell from \(4/5\) to \(3/5\), meaning A sacrificed \(1/5\). For exams, compare each old partner’s old and new share; equal shares indicate zero sacrifice.
