The combined share of Hema and Tara was 5 parts, with Hema holding 2 parts and Tara holding 3 parts.
Hema's share following the surrender is calculated as:
\[
Hema’s new share} = 2 - \frac{1}{3} \cdot 2 = \frac{4}{3} + \frac{2}{3} = \frac{8}{3}
\]
Tara's share following the surrender is calculated as:
\[
Tara’s new share} = 3 - \frac{1}{2} \cdot 3 = \frac{6}{2} - \frac{3}{2} = \frac{9}{2}
\]
Ojas's share is calculated as:
\[
Ojas’s share} = \frac{1}{3} \cdot 2 + \frac{1}{2} \cdot 3 = \frac{2}{3} + \frac{3}{2} = \frac{13}{6}
\]
The new shares for Hema, Tara, and Ojas are represented as:
\[
\frac{8}{3} : \frac{9}{2} : \frac{13}{6}
\]
After finding a common denominator and simplifying, the new ratio is:
\[
New Ratio} = 8 : 9 : 13
\]
