Step 1: Relate Radhika's Share to Her Ratio Part:
Profit Sharing Ratio = Radhika : Mehar : Shubha = 9 : 8 : 7.
Radhika's share (9 parts) = Rs 5,40,000.
Step 2: Find the Value of One Ratio Part:
Value of 1 part = Radhika's Profit / Radhika's Ratio Part
Value of 1 part = Rs 5,40,000 / 9 = Rs 60,000.
Step 3: Calculate Shubha's Share of Profit:
Shubha's Ratio Part = 7.
Shubha's Share = Value of 1 part \( \times \) Shubha's Ratio Part
Shubha's Share = Rs 60,000 \( \times \) 7 = Rs 4,20,000.
Conclusion:
Shubha's share of profit will be Rs 4,20,000.
