To determine Shubha's profit share, we must first calculate the total profit based on Radhika's given profit share and the profit-sharing ratio.
The profit-sharing ratio for Radhika, Mehar, and Shubha is 9:8:7, respectively.
This means Radhika is entitled to 9 parts, Mehar to 8 parts, and Shubha to 7 parts of the profit.
Radhika's profit share for the year is provided as Rs 5,40,000.
The total number of parts in the profit ratio is calculated as:
Total ratio sum = 9 + 8 + 7 = 24 parts.
Radhika's share represents \( \frac{9}{24} \) of the Total Profit.
Given that \( \frac{9}{24} \) of the Total Profit equals Rs 5,40,000, we can determine the Total Profit (P):
The equation is: \( \frac{9}{24}P = 5,40,000 \).
Solving for P:
\[ P = \frac{5,40,000 \times 24}{9} \]
\[ P = \frac{1,29,60,000}{9} \]
\[ P = 14,40,000 \]
The Total Profit is Rs 14,40,000.
Now, we calculate Shubha's share of the profit:
Shubha's share is \( \frac{7}{24} \) of the Total Profit.
\[ \text{Shubha's share} = \frac{7}{24} \times 14,40,000 \]
\[ = \frac{1,00,80,000}{24} \]
\[ = 4,20,000 \]
Therefore, Shubha's share of the profit amounts to Rs 4,20,000.
