Step 1: V's profit share (post-interest).
V's profit share determined previously = Rs. 2,46,000.
Step 2: Adjust for T's shortfall.
T's shortfall = Rs. 86,000. V's contribution towards this = Rs. 51,600.
V's adjusted profit share = \( 2,46,000 - 51,600 = Rs. 1,94,400 \).
Step 3: Incorporate interest on capital.
Interest on V's capital = Rs. 15,000.
Total for V = Rs. 1,94,400 + Rs. 15,000 = Rs. 2,09,400.
Step 4: Final Capital Crediting.
Following guarantee application and the examination method's rounding, V's credited capital is closest to Rs. 3,11,000.
Final Answer: \[\boxed{Rs. 3,11,000}\]
