Question

Q.Ashok and Sudha were partners in a firm sharing profits and losses in the ratio of 3 : 1. They admitted Bani as a new partner. Ashok sacrificed 14\frac{1}{4}th of his share and Sudha sacrificed 14\frac{1}{4}th of her share is favour of Bani. Bani's share in the profits of the firm will be : (A) 58\frac{5}{8} (B) 18\frac{1}{8} (C) 14\frac{1}{4} (D) 716\frac{7}{16}

Bani's share in the profits of the firm will be 14\frac{1}{4} (Option C).

Concept: Calculation of New Partner's Share on Admission

When a new partner is admitted, the existing partners sacrifice a portion of their profit share in favour of the incoming partner. The new partner's share equals the sum of the sacrifices made by all existing partners.

The sacrificing ratio measures what each old partner gives up. It is calculated as:

Sacrifice by a partner=Old share×Fraction sacrificed\text{Sacrifice by a partner} = \text{Old share} \times \text{Fraction sacrificed}

The new partner's total share is then:

New partner’s share=∑(Sacrifices by all old partners)\text{New partner's share} = \sum (\text{Sacrifices by all old partners})

This principle ensures that the profit-sharing arrangement remains mathematically consistent: what the old partners give up is exactly what the new partner receives.


Solution

Given data:

  • Old ratio (Ashok : Sudha) = 3 : 1
  • Ashok's old share = 34\frac{3}{4}
  • Sudha's old share = 14\frac{1}{4}
  • Ashok sacrifices 14\frac{1}{4}th of his share
  • Sudha sacrifices 14\frac{1}{4}th of her share

Working Note 1: Calculation of Sacrifice by Ashok

Ashok’s sacrifice=34×14=316\text{Ashok's sacrifice} = \frac{3}{4} \times \frac{1}{4} = \frac{3}{16}

Working Note 2: Calculation of Sacrifice by Sudha

Sudha’s sacrifice=14×14=116\text{Sudha's sacrifice} = \frac{1}{4} \times \frac{1}{4} = \frac{1}{16}

Working Note 3: Calculation of Bani's Share

Bani's share is the total of what both partners have sacrificed:

Bani’s share=316+116=416=14\text{Bani's share} = \frac{3}{16} + \frac{1}{16} = \frac{4}{16} = \frac{1}{4}

Verification: New Profit-Sharing Ratio

To confirm our answer, we can calculate the new shares of all three partners: …
