Question

Q.Prakhar and Rajan were partners in a firm sharing profits and losses in the ratio of 3 : 2 with capitals of ₹ 10,00,000 and ₹ 9,00,000 respectively. Siddharth was admitted as a new partner for 1/5th share in the profits of the firm. The new profit sharing ratio between Prakhar, Rajan and Siddharth was agreed at 12 : 8 : 5. The sacrificing ratio of Prakhar and Rajan will be : (A) 3 : 2 (B) 1 : 1 (C) 2 : 3 (D) 10 : 9

The sacrificing ratio of Prakhar and Rajan is 3 : 2, which is the same as their old profit-sharing ratio because Siddharth’s share is sacrificed by both partners in their old ratio.

When a new partner is admitted, the old partners give up a portion of their share in favour of the new partner. The ratio in which they sacrifice their profit share is called the sacrificing ratio. It is calculated as:

Sacrificing Ratio = Old Share – New Share

The question gives us the old ratio (3 : 2) and the new ratio (12 : 8 : 5). We need to find the share sacrificed by each old partner.

First, convert all ratios into fractions with a common denominator.

Old ratio of Prakhar and Rajan = 3 : 2

So, Prakhar’s old share = 3/5, Rajan’s old share = 2/5.

New ratio among Prakhar, Rajan, and Siddharth = 12 : 8 : 5

Total of new ratio = 12 + 8 + 5 = 25

So, Prakhar’s new share = 12/25, Rajan’s new share = 8/25, Siddharth’s new share = 5/25 = 1/5.

Now compute the sacrifice:

Prakhar’s sacrifice = Old share – New share = 3/5 – 12/25

Convert 3/5 to denominator 25: 3/5 = 15/25

So, sacrifice = 15/25 – 12/25 = 3/25.

Rajan’s sacrifice = Old share – New share = 2/5 – 8/25

2/5 = 10/25

So, sacrifice = 10/25 – 8/25 = 2/25.

Thus, the sacrificing ratio of Prakhar : Rajan = 3/25 : 2/25 = 3 : 2. …
