Step 1: Establish the relationship between Radhika's profit share and her portion of the ratio:
Profit Sharing Ratio = Radhika : Mehar : Shubha = 9 : 8 : 7.
Radhika's share, representing 9 parts, amounts to Rs 5,40,000.
Step 2: Determine the monetary value of a single 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: Compute Shubha's profit share:
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 allocated profit share is Rs 4,20,000.
