Explanation:

- A, B, and C have their initial capital in the ratio of 8:6:5.

- After 8 months, A withdraws 25% of his capital. So, A's effective capital for the year is 8 months of full capital and 4 months at 75%.

- C increases his capital by 20% after 8 months.

- To find the profit share for C, we calculate their relative capital over the year:

- A's adjusted contribution = $8\times 8+6\times 4=64+24=88$

- B contributes continuously = $6\times 12=72$

- C's adjusted contribution = $5\times 8+6\times 4=40+36=76$

- Total capital ratios become A:B:C = 88:72:76.

- Total profit is Rs 14000.

- C's share is $(76/236)\times 14000=4504.24$, roughly Rs 4000.

- Option:3, 4000 is the closest estimate and therefore correct.
