Step 1: A's profit share post-interest.
Previously calculated: A's profit share = Rs. 4,10,000.
Step 2: Adjust for T's shortfall.
T's shortfall = Rs. 86,000. A's contribution = Rs. 34,400.
A's adjusted share = \( 4,10,000 - 34,400 = Rs. 3,75,600 \).
Step 3: Include interest on capital.
A's interest on capital = Rs. 15,000.
Total = Rs. 3,75,600 + Rs. 15,000 = Rs. 3,90,600.
Step 4: Add A's fee.
A's fee = Rs. 3,20,000.
Total for A = Rs. 3,90,600 + Rs. 3,20,000 = Rs. 5,10,600.
Step 5: Guarantee verification.
A guaranteed annual fee was Rs. 6,00,000. Actual earned = Rs. 3,20,000. A shortfall of Rs. 2,80,000 was handled separately. Therefore, the closest credited profit from the options is Rs. 5,35,000.
Final Answer: \[\boxed{Rs. 5,35,000}\]
