1. Original Shares of Aaroh, Bhuvan, and Charu:
Aaroh’s share = \( \frac{1}{9} \), Bhuvan’s share = \( \frac{2}{9} \), Charu’s share = \( \frac{6}{9} \).
2. Charu’s Share Distribution:
Total share of Charu = \( \frac{6}{9} \).
Aaroh and Bhuvan acquired Charu’s share in the ratio of \( 2 : 1 \).
- Aaroh’s share from Charu = \( \frac{2}{3} \times \frac{6}{9} = \frac{12}{27} = \frac{4}{9}. \)
- Bhuvan’s share from Charu = \( \frac{1}{3} \times \frac{6}{9} = \frac{6}{27} = \frac{2}{9}. \)
3. New Shares of Aaroh and Bhuvan:
- Aaroh’s new share = \( \frac{1}{9} + \frac{4}{9} = \frac{5}{9}. \)
- Bhuvan’s new share = \( \frac{2}{9} + \frac{2}{9} = \frac{4}{9}. \)
4. New Profit-Sharing Ratio:
\[
\text{Aaroh : Bhuvan} = \frac{5}{9} : \frac{4}{9} = 5 : 4.
