Kishore and Bimal initially shared profits and losses in a 4:3 ratio. Upon Nand's admission for a \( \frac{1}{4} \) share, a new profit-sharing ratio is required.
Nand will receive \( \frac{1}{4} \) of the profits, leaving \( \frac{3}{4} \) for Kishore and Bimal.
Kishore and Bimal have agreed to share this remaining \( \frac{3}{4} \) equally, resulting in \( \frac{3}{8} \) profit share for each.
The sacrificing ratio is determined by calculating the difference between each partner's old and new profit shares.
Kishore: Old share = \( \frac{4}{7} \), New share = \( \frac{3}{8} \)
Bimal: Old share = \( \frac{3}{7} \), New share = \( \frac{3}{8} \)
The loss in share is calculated as follows:
Kishore's sacrifice = \( \frac{4}{7} - \frac{3}{8} = \frac{32}{56} - \frac{21}{56} = \frac{11}{56} \)
Bimal's sacrifice = \( \frac{3}{7} - \frac{3}{8} = \frac{24}{56} - \frac{21}{56} = \frac{3}{56} \)
The sacrificing ratio is therefore \( \frac{11}{56}:\frac{3}{56} \).
This simplifies to a ratio of 11:3.
The final sacrificing ratio between Kishore and Bimal is: 11:3.
