Kishore and Bimal initially share profits and losses in the ratio 4:3. When Nand is admitted for a $\frac{1}{4}$ share in profits, the new profit-sharing ratio needs to be determined.
The firm will now have Nand's share ($\frac{1}{4}$), leaving the remaining $\frac{3}{4}$ to be shared by Kishore and Bimal.
Since Kishore and Bimal now decide to share equally, the new ratio for them will be $\frac{3}{4}$ total profit share equally divided, i.e., $\frac{3}{8}$ each.
To find the sacrificing ratio, calculate the old share, new share, and the difference for both Kishore and Bimal.
Kishore: Old share = $\frac{4}{7}$, New share = $\frac{3}{8}$
Bimal: Old share = $\frac{3}{7}$, New share = $\frac{3}{8}$
Calculate the loss in share:
Kishore's sacrifice = $\frac{4}{7} - \frac{3}{8} = \frac{32}{56} - \frac{21}{56} = \frac{11}{56}$
Bimal's sacrifice = $\frac{3}{7} - \frac{3}{8} = \frac{24}{56} - \frac{21}{56} = \frac{3}{56}$
Therefore, their sacrificing ratio is $\frac{11}{56}:\frac{3}{56}$.
Simplifying this gives us a ratio of 11:3.
Thus, the correct sacrificing ratio between Kishore and Bimal is: 11:3.
To calculate the sacrificing ratio of Kishore and Bimal, follow these steps:
Step 1:} Calculate the old share of Kishore and Bimal. The old profit-sharing ratio of Kishore and Bimal is 4:3. \[ \text{Kishore's old share} = \frac{4}{7}, \quad \text{Bimal's old share} = \frac{3}{7}. \]
Step 2:} Calculate the new share of Kishore and Bimal.} After Nand’s admission, Kishore and Bimal decide to share profits equally, and Nand takes $\frac{1}{4}$ of the profits. The remaining share is: \[ 1 - \frac{1}{4} = \frac{3}{4}. \] Kishore and Bimal will share the remaining $\frac{3}{4}$ equally: \[ \text{Kishore's new share} = \frac{3}{4} \times \frac{1}{2} = \frac{3}{8}, \] \[ \text{Bimal's new share} = \frac{3}{4} \times \frac{1}{2} = \frac{3}{8}. \]
Step 3: Calculate the sacrifice made by Kishore and Bimal. Sacrifice = Old Share $-$ New Share \[ \text{Kishore's sacrifice} = \frac{4}{7} - \frac{3}{8} = \frac{32}{56} - \frac{21}{56} = \frac{11}{56}. \] \[ \text{Bimal's sacrifice} = \frac{3}{7} - \frac{3}{8} = \frac{24}{56} - \frac{21}{56} = \frac{3}{56}. \]
Step 4: Calculate the sacrificing ratio. \[ \text{Sacrificing Ratio of Kishore and Bimal} = 11:3. \]
