Explanation:

- The partners A, Y, and Z share profits in the ratio of 5:4:3.

- Total profit is Rs28,800 for the year.

- Sharing ratio calculation:

- A's share = \( \frac{5}{12} \times 28,800 \) = Rs12,000

- Y's share = \( \frac{4}{12} \times 28,800 \) = Rs9,600

- Z's share = \( \frac{3}{12} \times 28,800 \) = Rs7,200

- Z receives a guarantee of Rs10,000 minimum profit from A.

- Since Z's calculated share is Rs7,200, A covers the shortfall of Rs2,800.

- A's adjusted share: Rs12,000 - Rs2,800 = Rs9,200
