We need to find the gain or sacrifice of Shashi and Maya on Komal's retirement.
Step 1: Identify the old profit sharing ratio.
Old ratio of Shashi : Maya : Komal = 5 : 3 : 2
Total of old ratio = 5 + 3 + 2 = 10
- Shashi's old share = \(\frac{5}{10} = \frac{1}{2}\)
- Maya's old share = \(\frac{3}{10}\)
- Komal's old share = \(\frac{2}{10} = \frac{1}{5}\)
Step 2: Identify the new profit sharing ratio.
After Komal's retirement, Shashi and Maya decided to share profits in the ratio of 3 : 5.
New ratio of Shashi : Maya = 3 : 5
Total of new ratio = 8
- Shashi's new share = \(\frac{3}{8}\)
- Maya's new share = \(\frac{5}{8}\)
Step 3: Calculate gain or sacrifice.
\[
\text{Gain or Sacrifice} = \text{New Share} - \text{Old Share}
\]
For Shashi:
\[
\text{Change} = \frac{3}{8} - \frac{1}{2} = \frac{3}{8} - \frac{4}{8} = -\frac{1}{8}
\]
Negative means sacrifice. So Shashi sacrifices \(\frac{1}{8}\).
For Maya:
\[
\text{Change} = \frac{5}{8} - \frac{3}{10} = \frac{25}{40} - \frac{12}{40} = \frac{13}{40}
\]
Positive means gain. So Maya gains \(\frac{13}{40}\).
Step 4: Match with the options.
Shashi's sacrifice \(\frac{1}{8}\) ; Maya's gain \(\frac{13}{40}\) \(\Rightarrow\) This matches option (B).
Final Answer: (B) Shashi's gain \( \frac{1}{8} \) ; Maya's sacrifice \( \frac{13}{40} \)
